From 539916c4729bb44e1bba456e95b988aba9896920 Mon Sep 17 00:00:00 2001 From: Nicolas Maman Date: Wed, 4 Nov 2026 10:55:05 -0300 Subject: [PATCH 001/236] physics, ikrig, metrics: a foot under something stands on what is under it (#934) The ground under a foot was the first standable surface down from 0.6 m over it, so whatever hung over a foot within that was its ground. A figure stood with its heels 6 cm under a bench's edge (its underside 10 cm up) stood with its heels on the bench, 45 cm up; as a heel rose into the underside walking off, it took the bench's top for its ground and its right leg turned 74 rad/s (29 walking off the open floor). physics.ground_below reads the ground as a foot does: down from just under the underside of whatever is over the point (or from 0.6 m over it), the first surface a foot can stand on. A point that came into a solid from under it (the solid over a gap a foot fits in, 5 cm or more between its underside and the ground under it, and the point nearer that underside than the solid's top: a heel risen into a bench or a log's rounded flank) stands on what is under the solid. One pressed into a solid from over it (a sole a clip has in a ramp or a tread) or inside one resting on the ground (a step's riser a toe comes to, a block set under a foot) stands on its top, as before; read as come in from under it, test_humanoid's soles in its 20 degree ramp, a slab with room under its high end, were drawn 532 mm into it. An underside counts as over a point only with that room under it: a block's bottom flush on the floor over a sole at the floor's top is the block resting there, read from over it (taken as an overhang, test_anim_pipeline's foot over a block set under it read the floor under the block while its soles stood on the block's top, jumped 10 cm onto it in a frame and bent its toes 80 degrees; eased onto it as before, 4.4 degrees a step at the most). ikrig and the meter read the ground through it, and the meter how far a sole is in a solid as the shorter way out, up or down (static_depth): a heel risen 3 mm into the bench's underside read 347 mm, the depth to the bench's top. A point is in a solid only 1 mm or more under its surface (INSIDE_SKIN): one on it reads either way as a ray's rounding falls, and a heel standing on test_humanoid's floor read 600 mm into it. feet_reset forgets the toes' speed and the swing's clearance: read from where a moved figure's toe stood before, its speed raised a clearance and looked ahead for an edge as if it had swung there in a frame. test_feet_overhang: the mannequin standing with its heels under a bench's edge, then walking off: its heels on the floor (9.5 mm), no sole more than 3.0 mm into the bench, its fastest joint 29.4 rad/s as off the open floor. test_ground_queries: under the bench the ground is the floor (0.45 read from over it), risen into it from under it too; inside a step, and at the floor's top under it, the step's top; 1 cm into a ramp's top over room under it, the ramp. test_humanoid's stairs and ramp read as on 61964ad1 (a planted toe 1.6 and 4.5 mm, no sole into them).

Put on at the first blow alone, an unhurt person had no bodies, and ae3d.items' edge, which meets only moving bodies, passed through it. test_items: a person standing where a sword's edge passes, unhurt, is not hit (no bodies); made physical, it is hit once on its ragdoll. character.hit puts the bodies on through it as before. - character.pause(c), resume(c, at, facing), paused(c) (#942): held by something else (ae3d.motion's fall and get-up, a cutscene), the character leaves its object, mover and capsule alone and asks for no look or aim; resumed, the object is put where the body was left, the mover settled on it at rest and the feet planted afresh. Stepped on through it, a mover walked its object on at the last speed asked, under the body a fall held. test_character_pause: paused a second while asked to walk on, the object moves 0 mm; resumed 3 m aside facing back, it stands there (0 cm, 0 degrees) and walks 3.1 m in 3 s, a toe skating 2.1 mm. - Takes shared (#944): the gaits make a figure file's 14 takes (the stand, the eight gaits and mirrors, the starts and stops and their mirrors) once, keep them, and every character of that figure shares them (animator.share_take), the first one too. Each character read and retargeted every capture again, a camp of 20 settlers 20 times. test_character_share: 20 mannequins on one set of gaits play the same takes; the first is made in 227 ms, the others in 72 ms each; the first and the twentieth asked alike stay within 6e-8 rad of each other for 3 s, and with the first freed the others walk on alike. The gaits are freed after the characters on them, as every caller already did. - A slot that names no takes (#949) is held as it is reached, facing its way, until the figure leaves; it was refused, so a bedroll with no lie-down takes could not even be claimed and walked to. tests/fixtures/usable/spot.usable; test_use: from eight ways 3 m off, 1.1 cm off the approach point and 9.6 degrees off its way at the most, held until it left, a toe skating 0.57 mm while held. Walking there and turning, a toe skates 11.9 mm, as it does for every slot (#952).

A matcher's change inertializes without play, so it eased from a stale weight: walking on from a seat, a foot the frame picked had in the air read as down, its lock pulled the leg to the floor, and a thigh turned 34.7 rad/s (the takes' own 22.1), a toe skating 6.7 mm. The animator keeps the weights it gives the feet each frame, and a state's transition (play) eases out of those. A matcher's change takes its new frame's contacts as they are: its frames are re-picked every few tenths of a second, and eased there a foot stayed locked as the frame lifted it (32.2 rad/s at #906's check). test_humanoid 22: on character.match_add over 100STYLE's neutral takes, turned on the spot by 90 and 180 degrees (18.1 rad/s, the takes' own 22.1), then to a stool, sat on, stood up from and walked on: 15.2 rad/s, no sole into the ground, a toe skating 3.7 mm. test_anim_pipeline's matcher 17.8 rad/s within its 28.7.

A sharp turn read as a side or back step and crossed the feet; the plaza's worst went from 169 mm to 116 to 153 mm. - metrics.meter_trace prints one meter's feet each step: a foot held and thrown reads as a still stance and a fast swing, which no worst shows. - people_plaza: AE3D_WATCH_SIDE, AE3D_TRACE, AE3D_NOLOCK, AE3D_NOFEET.

The release eased the foot from the point it was let go toward where the clip has that point now: a point held still and a point already swinging off at 4 m/s, so the foot lagged and then sprinted to catch up. Now what the foot is off its clip by is taken as the release begins and faded out over RELEASE (inertialization's offset, as UE5 blends a foot lock out): the foot goes with the clip's swing from its first frame. The shuffle's hold where it got to over the release's last STEP_RISE is gone: with the offset faded the foot already goes with the clip, and held so through a swing's last frames a foot stopped dead and jumped on to the clip at 7.6 m/s.

The mover's curve (#969) turns a walker's way only about 20 degrees a second, so a 30 degree turn chosen to clear a meeting had not happened when the two met; and a neighbour in its own slow curve toward a new goal was read as going straight, so two walkers curving into each other were not seen until 2.3 m apart. Their capsules touched and shoved: a way swung 45 degrees in three steps over a locked foot and the feet crossed. Now mover.path runs the mover's own springs and curve rules ahead for each candidate way, mover.path_on predicts each neighbour doing as it does, and the reciprocal (RVO) meeting is read on those paths. The horizon is 4 s (at 2.5 s two plaza walkers still touched for 25 steps), neighbours are those that could meet within it, and a meeting's cost falls to nothing at the horizon. The mover's start and curve rules move into toward() and facing_toward(), shared by step and path, behaviour unchanged. people_plaza reports the closest two capsules come, the steps any touch, and the sharpest turn of a person's way. test_characters_avoid gains two walkers side by side turned across each other's way. Plaza, AE3D_TICK=60, 1200 frames, seeds 0 / 1 / 2, before -> after: capsules touching: 211 / 192 / 156 steps -> 0 / 0 / 0 closest capsules: -5 / -5 / -5 mm -> 4 (step 61, spawn) / 96 / 104 mm sharpest way turn: 61 / 58 / 59 rad/s -> 0.6 / 20.7 / 0.5 rad/s feet crossing: 129 / 113 / 140 mm -> 112 / 70 / 77 mm toe skate: 3.0 / 4.5 / 4.4 mm -> 3.0 / 4.5 / 4.4 mm fastest joint: 57 / 68 / 37 rad/s -> 57 / 70 / 35 rad/s Seed 1's 20.7 rad/s and 70 rad/s are runner 4 off the plaza, in a 7 m wide curve past the floor's edge (68 rad/s in the same runner before).

A blend sampled its second and later takes into work2 as well, so its pose a frame on was its last take's alone, and the easing took the gap for a joint's speed. A start's switch into a run eased a forearm from a "speed" of 56 rad/s; the quintic's guard cut the 0.3 s easing to 0.09 s, and the forearm turned 58 rad/s against the takes' own 14.7 (#937). A blend now has its own scratch pose. And a blend's time is its phase: a frame on is the frame's share of its cycle at its pace, as advance carries it, not a frame's seconds added to the phase. people_plaza: AE3D_EACH names each person's worst pop's joint. Measured at 60 Hz. People plaza, seeds 0 to 2: - fastest joint: 57, 68, 37 rad/s before; 52, 68, 35 after - crossing: 129, 113, 140 mm, unchanged - toe skate: 3.0, 4.5, 4.4 mm, unchanged A start probe (the plaza's mannequin stood 1 s and set off at 1.2 and 2.6 m/s, ahead, 26 degrees either side, 90 either side and behind, metered 3 s from the go), the fastest joint over the takes' own plus the easing's: - before: 2.36 at worst; the runs' forearms 55 to 60 rad/s at the switch - after: 1.54 at worst; the runs 0.91 to 1.34, their fastest a ball or foot joint at 23 to 34 rad/s, in the start's race before the switch The feet still cross up to 88 mm in the probe's starts: the start's race (below) is not fixed here. What is left: the plaza's start take (startstop_start.bvh) begins on the move, a shuffle to a stand at 0.56 m/s, so clips.moving_at marks its first frame and the start is cut from a stop's tail and a stand that travel 0.3 m in 1.6 s; the mover outruns it and its distance clock races up to 28 times real time. Cutting it from its move off a stand, with the clock held to 1.25 times real time and the gaits taking over once it falls 0.25 s behind, removed the crossing from every probe start and brought the probe to 1.08, but raised test_use's seat skate from 1.0 to 4.9 to 10.3 mm, so it is held back.

Three changes: - clips.moving_at reads a take that begins on the move from where it first stands, each stand and move held 0.1 s (a two-frame sway to 0.11 m/s at 0.92 s had read as the move): the StartStop start is cut about its move-off at 1.55 s. - animator.clock_most holds a distance clock to a share of real time (the character's starts 1.25), and once behind, the clock goes on by the distance gone each step, not by catching up at 1.25x: caught up so, a start 0.13 s behind played its stance at 1.25x its pace while the figure went 0.65 m/s, and a landing toe slid 10.7 mm. - animator.BEHIND, a condition on the clock's lag: the character's starts hand over to the gaits in step once 0.25 s behind. Why the race fix moved test_use's seats (log, approach 5, 1.0 to 10.3 mm): not the start itself. Changed timing put a turn step in the air at the frame the seat's enter began; the step landed during the enter's blend and slid 10 mm. A use now enters with both feet down. Before -> after: - set off from a stand at 1.2 and 2.6 m/s, ahead, left, right, behind (new test_humanoid check): fastest joint 196% -> 95% of the takes' own plus the easing's; a foot 116 mm -> -1.2 mm past the hips' middle. - test_use seats: worst toe skate 1.0 -> 0.19 mm; spot approach 3.7 -> 3.1 mm; walk-off along the log 2.8 -> 0.6 mm. - plaza at 60 Hz, seeds 0, 1, 2: crossing 112, 70, 77 -> 18, 0, 3 mm; skate 3.0, 4.5, 4.4 -> 3.3, 3.0, 3.0 mm; fastest joint 52, 68, 35 -> 23, 70, 22 rad/s (seed 1's is a gait loop seam at 2.6 m/s, not a start); toe thrown 4.7, 16.8, 3.9 m/s (seed 1's in a steady gait). - test_anim_pipeline's "walked and run off" line printed again (it had slipped into a comment): 57% and 78%.

It went on falling there, its arms reaching at REACH_STRENGTH and the balance at FALL_ASSIST pushing the heap up off the ground and along it at 0.2 to 0.5 m/s for two seconds and more before it tipped flat. Its pelvis within HEAPED (0.45 m) of the ground under it for HEAP_STEPS (a third of a second), it has landed now, and lets go as one lying does. Swept over the box man, struck at the chest forward and back at 3 to 15 m/s, on the servo and on muscles (100 falls), the two bisected commits (233c69ce, 2a6eaf91) reverted one at a time and together moved the mean from the blow to lying by under 0.15 s (2.94 s; 3.09, 2.99, 2.90): the single falls bisected in the issue are chaotic. The heap is what grew them. tests/test_fall_heap.ae, new: 48 such knock-downs (4 to 15 m/s). - heaped (falling, pelvis under 0.45 m): 0.50 s on average and 2.47 at the most before, 0.24 and 0.67 now; the chest carried along meanwhile 1.26 m on average, 0.79 now; - from the blow to lying 3.09 s on average, 2.79 now; over 3 s in 26, 18 now; every one lies and stands again within 15 s. Before, it fails three of its four checks. The issue's like (7 m/s forward, on the servo): lying 4.00 s after the blow before, 2.18 now; standing again 9.78 s, 7.73 now. At 5.5 m/s on muscles: lying 5.28 s, 2.12 now. At HEAP_STEPS of a sixth of a second, a fall sideways in test_falls was read as a heap as its knees gave, and its head met the ground faster (0.33 m/s against 0.28); at a third, test_falls's 90 falls come down exactly as before. Plaza (20 s, seeds 1 to 3), before and after: seeds 1 and 3 the same (heads spinning 0.12 s and 0.02 on seed 1). Seed 2: struck 15 and 12, walking again 9 and 10, 4.87 and 4.75 s from struck to walking, heads spinning 0.18 and 0.02 s, bodies walked through 0.5 and 2.0 s.

Its start broke three tests that its gate did not run, red on CI at 3b48a0b1 (linux-3, linux-4, macos, macos-2): test_feet_overhang (walking away from under a bench, a sole 350 mm into it), test_character_act (got up by a second act, a toe skating 28.9 mm) and test_physanim (easing back, a joint 14.6 rad/s against 13.8). Each sets off from a stand. Checked commit by commit: all three pass at 532ec670 and fail at a7bed32e. The fix comes back with every motion test in its gate.

The transition carried a foot of the stop's step to the act's stance 15 mm up (the clearance its swing keeps at speed). It slowed from 1.7 to 0.36 m/s and was drawn 12 mm up, but the landing rule read last frame's 15 mm clearance and did not land it. Under the take's glide it then went 0.40 and 0.82 m/s and slid 28 mm before it slowed again and landed. A foot going with its clip whose toe has slowed to SWING_SLOW or under is now read at the clearance it is let down to this frame (swing_clear, the clearance spring now shared with the solve). Read so at any speed, a run's start landed a foot a frame early, 0.5 mm past the hips' middle against -1.2 (test_humanoid), so only a foot no longer swinging is read so. test_items: the swing begun mid-stop 0.31 mm (27.8), from a stand 2.94 mm (11.1), the new check passes. test_humanoid as before (-1.19 mm). test_character_act 28.9 mm, test_feet_overhang 350 mm and test_physanim 14.6 rad/s fail as on the base, unchanged.

The second grip fell out of that arm's reach, the cause of #933's 163 mm. Now read from the pose as the hands' solve begins (animator.pose_unheld: layers, aims, lift, feet, look and body reach on, the hands not yet). - animator.pose_unheld: the pose kept just before hands_solve. - items: a two-handed kind's `hold` pose on both arms, each from its clavicle; a `mirrored` second grip (a bowl's, a tray's: the second hand mirrors the main, not stacked on the handle as on an axe); the hold pose eased off when the item is freed. - ikrig: fingers taken onto a handle come from the clip's over WRAP_IN (0.3 s, eased) instead of closing in one frame. - tests/fixtures/items/bowl.item: 26 cm across, 0.8 kg, cradled from under its sides, held in Walk_Carry_Loop's first frame. - test_humanoid: #933's cycle on the database figure: to a stool, sat on, given the bowl, stood up from with it and walked on. On that cycle (UE5 mannequin, stool_ual1, bowl in the right hand): - second palm off its grip once on: 145 mm before (carry on the main arm, graph-pose fit), 106 mm with the carry on both arms and the old fit, 0.098 mm after; - main palm off its grip: under 0.001 mm before and after; - fastest joint: 185.7 rad/s (hand_l) before; 122.5 (lowerarm_l, walking) with the fit fixed and the carry on one arm; 96 (ring_02_l, the rim wrapped in one frame) with both arms; after, 26.1 (calf_l), the same joint and number as the same cycle with no bowl, under the takes' own 22.1 plus the easing's 13.0; - a sole 0 mm into the ground, a toe skating 0.28 mm. The axe in test_items is unchanged: second hand 0.017 mm through a chop, fingers 10.5 rad/s through a walk, run and stop (takes' own 9.1).

then it walks on. Each measure is printed as worst and mean with the seed of the worst. 100 knockdowns in about 30 s. Checked, at the issue's bounds (all met): - every knockdown got up: 100 of 100; - up within 0.5 s of coming to rest: worst 0.217 s (seed 2), mean 0.185; - snapshot to clip, the pelvis no faster than the clip's own 1.22 m/s: worst 0.017 m/s under it (seed 76); - back to locomotion, the pelvis no faster than its walk's: worst 0.027 m/s under it (seed 71); - never falling again: 0 of 100. Measured and not met yet, checked with AE3D_KNOCK_ALL=1: - snapshot to clip, no joint past the clip's own fastest (27.9 rad/s): worst 158 rad/s past (seed 85), mean 74.0; - the capsule within 5 cm of the pelvis: 0.239 m every time, the offset of LayToIdle's first-frame pelvis from its root; - back to locomotion, no joint past the gaits' own fastest (14.7 rad/s): worst 10.3 rad/s past (seed 89), mean 1.4 under.

Solved on a figure lying in a get-up clip (UAL2's LayToIdle laid on a fallen mannequin), the look turned the head from its face toward a point at eye height ahead and threw it up to 186 rad/s for a frame, and the feet's locks threw a foot up to 127, against the clip's own fastest 27.9. A figure handed back lying also kept the look's weight it had walking, as the look is not solved while the animator is paused. ikrig.trunk_upright reads how upright the trunk stands from the line from its pelvis to its chest: wholly from a 60 degree lean (a deep bow), not at all from 78 (lying), smoothstepped between. The look's weight is held to it at once, and eased back in at its own rate as the trunk rises; the feet's contact and plant weights are given that share of themselves. A standing figure reads exactly 1, so nothing upright changes. tests/test_knockdowns.ae, 100 seeded knockdowns, snapshot to clip, a joint past the clip's own fastest: - before: worst 158 rad/s (seed 85), mean 74.0; - after: worst 96 rad/s (seed 64, a foot), mean 12.8. Back to locomotion, a joint past the gaits' own: worst 10.3 rad/s (seed 89) before and after. The other measures are unchanged.

The mannequin's 100STYLE move blend at 1.2 m/s: 32 frames over a 0.987 s cycle, going 1.199 m/s as the graph does, its seam 0.136 rad against 0.248 inside, and 0.036 rad off the graph's own pose at the figure's phase (half a frame's step bounds it). Baked in 0.45 ms. - Update-rate LOD (animator.set_every, update_every, graph_cost): the graph evaluated one frame in N, ahead to the last frame it serves, each frame drawn between, so the frame is drawn at its own time, not an interval late. Its feet and eyes are solved where the figure will stand (a knee was 0.16 rad off at 1 in 4 when solved where it stood), and its feet unlocked as UE turns foot IK off on low LODs (a lock sampled at 1 in 8 put a knee 1.0 rad off). Against a figure drawn every frame with its feet unlocked: 0.13 rad at 1 in 4, 0.18 at 1 in 8, but the toes' peel flick (0.15, 0.36 with them); no joint faster than every frame (6.5 and 4.3 rad/s against 10.3); back to every frame with no jump, and identical to the every-frame figure a second on (3e-8 rad). - A budget allocator by significance (animlod.Budget, UE's Animation Budget Allocator): distance, four times off the view, ranked by an insertion sort kept frame to frame, each figure the fastest of 1, 2, 4 and 8 that keeps the graphs' measured costs within the budget, nearest first and no faster than a nearer one, staggered by rank. Sixteen walkers at 35% of their 2.9 ms: 1.0 ms planned, the nearest every frame, the farthest one in 8. - Hand-over between a crowd instance and the full graph by pose snapshot (animlod.enter, enter_character, leave; animator.take_over; mover. settle_moving): in, the graph takes over from the bank's two poses about the instance's phase and inertializes the difference, its parameters bound first; a standing mannequin handed a walk turns 8.2 rad/s on its first frame and 10.45 at most over its first second (the walk's own 10.56), 0.015 rad off the bank after. Out, the drawn pose matched to the bank's frames: phase 0.018 against the graph's 0.030, 0.125 rad off what it drew (its feet and eyes). The animator's evaluation is split (evaluate_graph, read_paused, draw_between) with every-frame behaviour unchanged: test_anim_pipeline, test_humanoid, test_character_share, test_locomotion, test_metrics and test_gltf pass.

Each is now ikrig's: limb_points (the reach by limb_span, the middle joint by ik.triangle), limb_folded and limb_bend_for, which ikrig.limb_solve stands on too. Motion keeps only what is its own, turning its ragdoll bodies onto the two points. No change in results: test_ik_constraints prints the same as before for every check it had; test_motion_parts, test_get_up_feet, test_falls, test_fall_heap, test_muscles, test_knockdowns and test_character_act are the same byte for byte; test_get_up differs in the sixth digit of one hand-over number (0.0802999 to 0.0802993 deg, round-off of the triangle's other form); test_physanim only in its timing. test_ik_constraints gains two sections: - two bones as points, over 1600 targets from 5 mm off the root to 18 cm past full reach: bones 3e-13 mm off their lengths, bent 150 degrees at most against their most of 150, no middle joint to the wrong side, an end in reach on its target and one out of reach on the nearest point it can come to (0 mm), limb_bend_for and limb_folded agreeing within 3e-14 degrees; - the cost of each solve from the mannequin's idle, the program at -O0 as CI builds it: two bones on points 0.04 microseconds, a limb 0.8, a FABRIK spine of five 55, the look 37, the aim 31, the whole body reaching past its arm 80 (at -O2: 0.005, 0.3, 20, 2.8, 3.5, 12).

The one left swung -// back through upright from a lean held over its feet and fell on its -// back (#749); -// - shoved from behind at 0.7 m/s, which its balance holds over its -// feet, at the same 13 angles, fresh and up again, it comes back -// upright and stops there: it never goes down, and its centre of mass -// goes no more than 5 cm behind where it stood (#749). Its assist had -// righted the lean as hard as its torque let it all the way back, -// braking only within a degree of upright: the body swung back through -// upright at up to 0.9 m/s, its centre of mass 20 cm behind where it -// stood on average and 99 cm at most, and it stepped back 21 times. +// Part 1, the way down and up, as the engine offers it: // -// Each push is a shove (motion.shove, over 0.15 s), as a hand pushes. +// - the knockdown: character.knock, the character and its animator +// paused, its physanim bodies let go wholly and powered as they go down +// (physanim.knock), its legs giving, landed then a ragdoll, the blow on +// a body; +// - rest: character.down (landed, its pelvis and chest still); +// - the pose snapshot: what the paused animator read back of the drawn +// ragdoll (the get-up blends out of it); +// - the get-up clip: UAL2's LayToIdle, the one get-up the mannequin has +// (UAL1's file has none), or its mirror, chosen by how the body lies; +// - up in one call (character.get_up): the capsule under the body and the +// clip onto where the body lies, its object put where the clip's first +// frame has the pelvis on the body's pelvis, facing so the clip's spine +// lies along the body's; inertialized back, the clip played as an act +// from the pose drawn, and at its end the stand taken up, then the walk. +// +// Held to, over the knockdowns (worst and mean printed, the seed of the +// worst): +// +// - up within 0.5 s of coming to rest: from the moment its pelvis and +// chest came to rest (under REST_SPEED) to the get-up clip's start; +// - no pop at the change from snapshot to clip: from the switch until a +// second on, no joint drawn turning faster than the clip's own fastest +// (metrics.POP against metrics.take_fastest), and the drawn pelvis no +// faster than the clip's own pelvis; +// - the capsule within 5 cm of the pelvis (level) as the get-up starts, +// at every step of it, and once it stands; +// - back to locomotion without a pop: from the act's end, asked to walk, +// no joint faster than the gaits' own fastest and the pelvis no faster +// than its own walk's, measured on it two seconds on;

A mirror and a matcher's features read a compressed take without unpacking it. --- src/ae3d/animator/module.ae | 48 +++++++- src/ae3d/animgraph/module.ae | 220 ++++++++++++++++++++++++++++++++++- src/ae3d/clips/module.ae | 12 +- tests/test_animgraph.ae | 37 +++--- 4 files changed, 290 insertions(+), 27 deletions(-) diff --git a/src/ae3d/animator/module.ae b/src/ae3d/animator/module.ae index 5a5b1d39..37d21cf2 100644 --- a/src/ae3d/animator/module.ae +++ b/src/ae3d/animator/module.ae @@ -58,7 +58,7 @@ exports ( current, current_take, state_name, find_state, state_time, set_rate, rate, transitioning, transition_offset, transition_seconds, transition_need, set_root_motion, root_moved, ground_speed, add_layer, layer_weight, layer_restart, layer_time, layer_rate, layer_done, face_on, face_off, blink, blinker, saccades, look, speak, speak_off, - set_feet, feet, set_hands, hands, look_at, look_off, aim_at, aim_off, trunk_aim, set_body, body, evaluate, pose_now, pose_graph, pose_unheld, pose_shown, add_post, remove_post, show, set_fixed, fixed, + set_feet, feet, set_hands, hands, look_at, look_off, aim_at, aim_off, trunk_aim, set_body, body, evaluate, pose_now, pose_graph, pose_unheld, pose_shown, add_post, remove_post, hold, show, set_fixed, fixed, contact_weight, plant_weight, figure_object, update_now, event_count, event_name, fired, take_over, set_every, update_every, graph_cost, state_sample, @@ -286,6 +286,7 @@ struct Animator { // Secondary motion (#989, springs_of): spring chains and jiggle solved // after the IK; null with none. springs: ptr // *Springs (ae3d.springs) + helds: ptr // list of *Held: uses of shared takes, let go of with it (hold) } // A step after the graph, and what it steps with (add_post). @@ -294,6 +295,12 @@ struct Post { state: ptr } +// A use of what another owner shares with the animator (hold). +struct Held { + release: fn(ptr) + state: ptr +} + // A change into a state drawn by its owner (play_shaped): `run(state, a, // out, t)` given the state's pose at `t` seconds into it, `time` long. struct Shaper { @@ -433,6 +440,7 @@ attach(e: *Engine, o: *GameObject) -> *Animator { a.work3 = pose.new(rig) a.blend_work = pose.new(rig) a.posts = list.new() + a.helds = list.new() a.shown = pose.new(rig) a.every = 1 a.step_now = pose.new(rig) @@ -532,6 +540,15 @@ animator_free(a: *Animator) { free(a.down_drawn) free(a.plant_drawn) free_graph(a) + // Its uses of shared takes, once nothing of it plays them. + i = 0 + while i < list.size(a.helds) { + h = list.get_raw(a.helds, i) as *Held + h.release(h.state) + heap.free(h) + i = i + 1 + } + list.free(a.helds) pose.rig_free(a.rig as *pose.Rig) heap.free(a) } @@ -3098,6 +3115,19 @@ add_post(a: *Animator, run: fn(ptr, *Animator), state: @keep ptr) { list.add_raw(a.posts, step as ptr) } +// A use of what its owner shares with this animator (takes share_take +// gave it: a graph file's, ae3d.animgraph), let go of by `release(state)` +// as the animator is freed, after everything that plays them.

On the captures and the glTF takes at 0.1 mm nothing goes (one frame of the walk dropped moves the skin 6 to 25 mm, of a stand 0.2 to 0.4 mm); a stretch held goes whole. test_anim_memory: a file parsed once and its meshes shared (a morphed one each scene's own), a held stretch's frames dropped within the bound, and 12 runners on one graph file sharing its compressed takes, the file parsed once, each past the first under 2 MB of its own. gltf.parses counts. --- src/ae3d/clips/module.ae | 196 +++++++++++++++++++++++++++++-- src/ae3d/gltf/module.ae | 8 +- tests/test_anim_memory.ae | 236 +++++++++++++++++++++++++++++++++++++- 3 files changed, 428 insertions(+), 12 deletions(-) diff --git a/src/ae3d/clips/module.ae b/src/ae3d/clips/module.ae index fd029d98..28836304 100644 --- a/src/ae3d/clips/module.ae +++ b/src/ae3d/clips/module.ae @@ -36,7 +36,7 @@ exports ( frame, sample, sample_frame, extract_root, root_under_pelvis, root_joint, travel, root_delta, has_root_motion, contact, planted, find_contacts, contacts_like, speed, even_root, foot_down, phase_of, time_at_phase, time_of, ground_point, up_of, heading, ground_carry, - compress, compressed, compress_error, take_bytes, track_kinds, COMPRESS_ERROR + compress, compressed, compress_error, take_bytes, track_kinds, keys_kept, COMPRESS_ERROR ) extern calloc(count: int, size: int) -> ptr @@ -1681,6 +1681,11 @@ braking_from(t: *Take) -> (float, float) { // shared out along the longest chain.

Traced step by step, both the same: a struck person got up beside or under the car where it stood. Its capsule, stood up into the car's box, was pushed out by the mover 0.85 m (seed 5) and 1.3 m (seed 2) in one step; physanim's kinematic hips and legs, driven onto the rig at the speed that takes, went after it at 48 and 75 m/s with no mass to give, and hit the car's wheels and box.

A character paused with its ragdoll let go to another writer (physanim.released: a fall) is now its bodies on the ground: each body's capsule, its two ends and its middle (physics.ragdoll_bone_segment), a neighbour standing still as wide as the capsule, the body met when any of them is, and the meeting counted once per body. A body lying turns no way, so its meeting is read against the walker's own way (not RVO's 2v - v_mine - v_theirs) and weighs twice a person's share: at a person's share the turn to clear a body lying along the way cost more than the meeting until the walker was already in it, and it walked through the body unturned. test_walk_round_body (new): the mannequin knocked down LIMP 3 m ahead of another asked to walk straight on at 1.2 m/s, 16 seeds; before / after: the walker's capsule kept -0.265 / +0.063 m off the lying bodies' capsules at least (32 seeds after: +0.063); got past it, 1.5 m beyond: 3.28 / 3.59 m at least.

A struck person asked to get up while the car stands over it (character.GET_UP_WAIT) lies on and is asked again the next step; handed over regardless, it was put in RISING with no get-up played. - Measured every step and reported (#982): the car's chassis risen over its ride height and its fastest up, any person's body fastest up and highest, and the seconds get-ups waited. AE3D_LAUNCH=1 prints what goes up faster than the car comes (7 m/s): the car, the people within 3 m of it and the fastest's bodies; AE3D_LAUNCH_AT=n prints steps n to n+30 body by body, with the car's wheels. Seeds 0 to 9, 4,800 steps at AE3D_TICK=60, the car's fastest up and its most over its ride height, before (da0b8a11) / after: seed 2: 15.7 m/s, 11.7 m / 2.65 m/s, 0.46 m; seed 5: 15.8 m/s, 12.2 m / 0.76 m/s, 0.02 m; the other eight: under 1.2 m/s and 0.18 m / under 1.5 m/s and 0.21 m, but seed 0, 2.5 m/s and 1.35 m: a struck body squeezed under the braked car off the plaza's edge lifts it (not a get-up; left open).

Moved out of the plaza ramp's side, a foot walking along its edge was put off it and in it by turns, 29 mm in and a calf at 68 rad/s. - It goes out the way it went out last frame while that comes out within WALL_KEEP of the shortest (physics.static_way_along): out of its shortest way alone, a toe in a deck's corner went out of one face, then the other. - physics.ground_below no longer takes a point nearer a hanging solid's side than its underside as come in through the side: off_walls no longer needs it, and it put a walker's sole 6 mm into the ramp's edge. - test_feet_edges measures a toe thrown past its clip too. --- src/ae3d/ikrig/module.ae | 56 ++++++++++++++++++++++++++----- src/ae3d/physics/module.ae | 69 +++++++++++++++++--------------------- tests/test_feet_edges.ae | 34 +++++++++++-------- 3 files changed, 99 insertions(+), 60 deletions(-) diff --git a/src/ae3d/ikrig/module.ae b/src/ae3d/ikrig/module.ae index c2f87a97..e542d1c9 100644 --- a/src/ae3d/ikrig/module.ae +++ b/src/ae3d/ikrig/module.ae @@ -333,6 +333,7 @@ struct Feet { toe_speed: ptr // float[2]: how fast each toe goes over the ground, metres a second clears: ptr // float[2]: the least each sole is kept over the ground (SWING_CLEAR), on its spring clear_speeds: ptr // float[2]: and how fast that changes + wall_ways: ptr // float[4]: the level way each foot went out of a wall last frame (off_walls), x and z; 0 0 for none ground_known: bool stand_now: bool // the next solve stands the feet on the ground at once (feet_stand) stride: float // of the clip's stride, how long the feet step (feet_set_stride) @@ -934,6 +935,7 @@ feet_new(rig: *pose.Rig, o: *GameObject) -> *Feet { f.pivot_ask = calloc(2, 8) f.memo = calloc(GROUND_MEMO * MEMO_FLOATS, 8) f.near = physics.static_near_new() as ptr + f.wall_ways = calloc(4, 8) f.stride = 1.0 find_soles(f, rig) flesh_feet(f, rig) @@ -1078,6 +1080,7 @@ feet_free(f: *Feet) { free(f.pivot_ask) free(f.memo) physics.static_near_free(f.near as *physics.StaticNear) + free(f.wall_ways) limb_free(f.limb_l as *Limb) limb_free(f.limb_r as *Limb) heap.free(f) @@ -1567,19 +1570,25 @@ foot_ground(f: *Feet, rig: *pose.Rig, worlds: ptr, side: int, clip_ankle: Vec3, // the ground under it (ground_at) or over itself, the higher; one in a solid // there whose shortest way out is level (physics.static_way_out) is in a // wall's face (a top over what a foot steps up, ground_at; a slab's side -// over a gap), and the foot goes out of it that way by the deepest, WALL_SKIN -// off the face, WALL_PASSES times for a corner.

The clip's own left foot drifted 29 cm off the lock (the blend's weights swinging and the facing turning 0.9 rad/s), just under LOCK_SLIP, so the lock never let go: the foot drawn 179 mm past the hips' middle, the clip's own 100 to 214 mm short of it. Now a locked foot is let go as a slip (lock_crossed) when it is drawn past the hips' middle toward the other foot's side while the body itself goes over it sideways (0.1 m/s or faster, by the figure's place over the ground, Feet.going) and the clip keeps that foot on its own side, 2 cm or more further out than the lock. Judged against the clip's own foot: a catwalk's or a run's own crossing is left to the clip, and a side gait's stance foot, which never comes past the middle drawn, is held as the clip has it. Let go, the foot is drawn no further past the middle than the middle itself, as it is let go and through its step (not_past_middle), its step carries it from its first frame, and once down it is held again at once (left to a blend 93 to 97% down it went along the floor with the clip's drift: a toe skated 77 mm beside a neighbour). Tried and not kept: read 0.1 s ahead at the body's rate, the 2D blend's side steps (drawn and clip stance feet 50 to 60 mm apart by the blend's drift alone) were let go 50 mm out and a toe slid 21 to 55 mm; ahead at the rate the drawn foot nears the middle, a walk's hip sway let straight-walk stance feet go 45 to 117 mm out; a foot set down mid-release caught where drawn (088be2b3) broke the start/stop's 5 mm slide (33 mm), and is left out.

for `seconds` its owner's run(st, a, out, t) is given the state's pose `t` seconds in, before the layers, the aims and the IK, and writes the pose drawn in place of the inertialization. Any other change ends it; shaping(a) says whether one is under way. What it is for (the next commits): a get-up planned from a pose snapshot (character.get_up). Eased out of the pose a body lay in joint by joint, each joint's offset decayed along its own shortest way and the pelvis dropped while the trunk turned over, and the drawn limbs swept through the floor: a forearm 34.8 cm under it at the worst over 100 knockdowns (test_knockdowns, seed 70), mean 19.9 cm.

Lifted frame by frame by the depth itself, the pelvis went 1.9 m/s against LayToIdle's own 1.22; - each arm and leg's elbow or knee, end, and fingers or toes turned up off the ground about the joint before it (ikrig.lift_turn) on lifts planned ahead the same way, each about an axis averaged as its turn is (steady_axes). Lifted frame by frame, or with each limb's side read off a triangle, joints turned up to 188 rad/s against the take's own; - the end carried by its bone as it is lifted (held to its turn in the world, a hand turned against its forearm at the lift's own speed); - the get-up's first moment drawn as planned before the animator reads it (the ragdoll draws a thumb up to 8 cm through the floor). Its take's own frames are kept out of the floor as it is added (ground_take, get_up_add): LayToIdle has a forearm 5.4 cm under it, the fingers 3.4 and the balls of the feet 3.4. Its head is the take's own while it acts (looked ahead while still crouched, the chest pressed a fingertip 2.3 cm into the floor). get_up_cost(c) gives what the planning and each frame of it cost. test_knockdowns holds no joint more than 2 cm under the floor at any step of the get-up, and prints the costs. 100 knockdowns, before -> after: a joint under the floor: 0.348 m (seed 70), mean 0.199 -> 0.0142 m (seed 73), mean 0.0063 snapshot to clip, joint: 1.98 rad/s under (seed 14) -> 0.37 under (seed 2), mean 6.04 under (against the take's own 26.55, its grounded frames; 27.86 before) snapshot to clip, pelvis: 0.018 m/s under (seed 4) -> 0.110 under (seed 69) capsule off the pelvis: 0.08 mm -> the same up after rest: 0.183 s (seed 5) -> the same fell again: 0 of 100 -> the same back to locomotion, pelvis: 0.034 m/s under (seed 69) -> the same back to locomotion, joint (gated): 5.62 rad/s past (seed 89) -> the same Costs on this machine, -O2 (-O0): planning a get-up 0.77 ms mean, 1.36 worst (7.7 ms mean); each frame of it 0.033 ms (0.30); adding the get-up, its take rooted and grounded, 2.0 ms (13.9). test_get_up_pair: 0.67 s inside each other over its 9 layouts, 5.0 cm at the deepest -> 0.55 s, 7.3 cm (#835, printed, not held).

Its trail of hashes joins the determinism trail CI compares across platforms. --- .github/workflows/ci.yml | 10 +- changes/2026-11-09-net-anim.md | 25 + ci.sh | 2 +- docs/architecture.md | 2 +- docs/networking.md | 31 + src/ae3d/netanim/module.ae | 1281 ++++++++++++++++++++++++++++++++ tests/test_net_anim.ae | 656 ++++++++++++++++ 7 files changed, 2004 insertions(+), 3 deletions(-) create mode 100644 changes/2026-11-09-net-anim.md create mode 100644 src/ae3d/netanim/module.ae create mode 100644 tests/test_net_anim.ae diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index 2048074d..8a7aa089 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -737,7 +737,10 @@ jobs: # the suites.

A peer compares it with what it had at that tick; parted, its place and facing are eased onto the owner's (a half-life of 0.1 s, at most 0.5 m/s: never snapped), its springs' velocity taken (`mover.correct`), and its graph played at the owner's state and time, inertialized over 0.2 s. +- **A ragdoll as physics state.** While a figure is down, ten times a second its bodies' places (a tenth of a millimetre about the first) and turns (47 bits), compared with the peer's own. + +Measured (`tests/test_net_anim.ae`: the mannequin on 100STYLE's gaits standing, walking, running, turning, stopping with its eyes on a point, knocked down and up again, walking on): from the same input stream every joint of the client's figure is the host's to the bit at every tick, and its trail of hashes goes into the determinism trail; under 150 ms of latency, 30 ms of jitter and 5% loss, over three seeds of the hub, the client's feet and hands are the host's at every tick (the inputs came in time; 2 ticks of 1,212 played before theirs came on one seed, a walk held). A figure streams 538 bytes a second walking, 2 KB a second down (its ragdoll), 876 over the script; a remote figure costs netanim under a microsecond a frame, its whole frame (graph, mover, feet, physics) about 0.2 ms. A sixth of a second of a figure's inputs lost whole as it sets off leaves it 3 cm behind; the states find it and ease it back, its object within 0.6 mm of the host's. Its feet's locks are not in the state yet, so a foot planted a tick apart from the host's still shows for a step (up to 5 cm), and a peer's ragdoll is compared with the owner's but not yet put on it where they part. + ### The same on every platform **What makes a tick the same everywhere.** A tick is `ae3d.horde`'s and `ae3d.nav`'s passes in a fixed order: the headings turned toward the field (`flow_steer`), the velocities along them (`wander`), the separation, and the step, by 1 / the tick rate, never a frame's delta, then the shoves, each moving only its own zombie. Each pass works a figure at a time over the pool and writes only that figure, so the pool's size and its timing change nothing. With one exception, found on the way: the separation with no pool visits each pair once and pushes both, which adds the same pushes in another order than the pool's gather, and 1,773 of the 4,500 velocity components of a knot of 1,500 differ in their last bits. `horde.separate_exact` gathers at any thread count, and is what the horde steps by. The flow field's headings were libm's `atan2`, which isn't the same function on every platform; a cell points one of eight ways, so they are eight constants now. What is left of libm is `sqrt`, `floor` and `fabs`, exact everywhere, beside the horde's own polynomial sine and arctangent. A figure's pose bank (`set_figure`, when the walk drives the step) has to be the same bytes on every side too: its travel table is in the step. diff --git a/src/ae3d/netanim/module.ae b/src/ae3d/netanim/module.ae new file mode 100644 index 00000000..86db93e6 --- /dev/null +++ b/src/ae3d/netanim/module.ae @@ -0,0 +1,1281 @@ +// ae3d.netanim -- a character over the network (#911). +// +// A figure is not sent a pose at a time.

Figures told together are ordered whichever is told first: one whose best way goes into a body near looks again at the next step and yields to one waiting near whose way goes in less, so the clearer rises first and the other waits while its way would cross it. get_up_cost's planning now counts the scoring too. --- src/ae3d/character/module.ae | 610 +++++++++++++++++++++++++++++++++-- 1 file changed, 582 insertions(+), 28 deletions(-) diff --git a/src/ae3d/character/module.ae b/src/ae3d/character/module.ae index 96884316..b9c8d8f2 100644 --- a/src/ae3d/character/module.ae +++ b/src/ae3d/character/module.ae @@ -60,7 +60,7 @@ exports ( Character, Gaits, gaits, gaits_set, gaits_free, GAIT_FW, GAIT_BW, GAIT_SW, GAIT_FR, GAIT_BR, GAIT_SR, GAIT_START, GAIT_STOP, GAIT_STAND, humanoid, graphed, graph_of, character_free, capsule_off, match_add, matching, use_takes, use, leave, using, pause, resume, paused, seated, use_phase, use_contact, use_enter_state, USE_NONE, USE_GO, USE_TURN, USE_ENTER, USE_LOOP, USE_EXIT, move, look, look_ahead, look_free, aim, aim_off, aims, - act, act_stop, acting, ACT_OUT, swing, get_up_add, get_up, get_up_count, get_up_state, get_up_cost, set_avoidance, avoiding, hit, physical, physanim_of, animator_of, mover_of, feet_of, object_of, idle_state, move_state, standing, error + act, act_stop, acting, ACT_OUT, swing, get_up_add, get_up, get_up_waiting, get_up_count, get_up_state, get_up_cost, set_avoidance, avoiding, hit, physical, physanim_of, animator_of, mover_of, feet_of, object_of, idle_state, move_state, standing, error ) // Seconds a character's look and aim ease on and off. @@ -150,6 +150,17 @@ struct Character { get_up_count: int planned: ptr // *Planned: its get-up's hand-over (get_up), made at its first getting_up: bool // its act is a get-up (get_up): its head the take's own + up_paths: ptr // ptr[GET_UPS]: each get-up's way, sampled about its object (way_of) + up_path_n: ptr // int[GET_UPS]: how many samples each + up_index: int // the get-up it plays, its place in get_ups; -1 none + up_at: Vec3 // where its first frame was laid (lay_onto) and the way it faced + up_facing: Vec3 + up_waiting: bool // told to get up, waiting for room (get_up) + up_motion: ptr // *Motion it lies in while it waits + up_blend: float // the blend it was told + up_waited: float // seconds it has waited + up_look: float // seconds to its next look for room + up_into: float // metre-seconds its best way went into what is near, at its last look (way_overlap) graph: ptr // *Graph read from a file (graphed), or null stepper: ptr // *Behaviour: its step in the engine's loop } @@ -439,6 +450,9 @@ humanoid(e: *Engine, name: string, path: string, g: *Gaits, scale: float = 1.0) c.use_names = calloc(USE_TAKES, 8) c.use_states = calloc(USE_TAKES, 4) c.get_ups = calloc(GET_UPS, 4) + c.up_paths = calloc(GET_UPS, 8) + c.up_path_n = calloc(GET_UPS, 4) + c.up_index = 0 - 1 c.ready = 0 - 1 c.matcher = 0 - 1 c.idle = 0 - 1 @@ -808,6 +822,13 @@ character_free(c: *Character) { free(c.use_names) free(c.use_states) free(c.get_ups) + k = 0 + while k < c.get_up_count { + free((c.up_paths as ptr[])[k]) + k = k + 1 + } + free(c.up_paths) + free(c.up_path_n) planned_free(c.planned as *Planned) if c.use_source != null { string.release_kept(c.use_source) } if c.mover != null { mover.mover_free(c.mover as *Mover) } @@ -917,6 +938,8 @@ act(c: *Character, state: int, blend: float) -> bool { if state >= animator.state_count(a) { return false } c.acting = true c.getting_up = false + c.up_waiting = false + c.up_index = 0 - 1 c.act_state = state animator.set_root_motion(a, true) animator.play(a, state, blend) @@ -932,6 +955,8 @@ act_stop(c: *Character, blend: float) { mover.settle(c.mover as *Mover) c.acting = false c.getting_up = false + c.up_waiting = false + c.up_index = 0 - 1 c.act_state = 0 - 1 } @@ -996,6 +1021,9 @@ get_up_add(c: *Character, title: string) -> int { get_up_state_of(c: *Character, title: string, t: *Take) -> int { state = animator.add_state(c.animator as *Animator, title, t, false) (c.get_ups as int[])[c.get_up_count] = state + way, n = way_of(c, t) + (c.up_paths as ptr[])[c.get_up_count] = way + (c.up_path_n as int[])[c.get_up_count] = n c.get_up_count = c.get_up_count + 1 return state } @@ -1026,30 +1054,116 @@ get_up_state(c: *Character, i: int) -> int { // from the pose drawn (longer where the pelvis drawn would go faster // than the get-up's own, get_up_blend), its root motion moving the capsule, and at its end // the stand taken up. -// Done by hand in another order, the drawn pelvis jumped 1.3 m.

People turn top down (Hollands and Patla, Paquette): the eyes and head lead, then the chest, the pelvis, the feet last; 30 degrees takes no step, 90 about 2 and 180 3 to 4 (more is a clinical sign). - ikrig.feet_turn_to: the turn asked of feet that step. The feet plan it as a whole: no step while both stand within TURN_HOLD (40 degrees) of it, the hips taking it; past that, open and closing steps: the foot on the turn's side opens TURN_OPEN past the body once the body has turned TURN_ONSET past it, the other closes beside it, each landing in the clip's stance turned to its heading; one foot down before the other lifts, and the standing foot pivots on its toe's tip (TURN_PIVOT) while the other steps. - turn_lead: the spine, neck and head turned toward the way to face (the head up to 69 degrees, the chest a third of it), never past it. - ikrig.feet_turn_reach: the body turns no further than TURN_REACH past a planted foot's stance, so its yaw follows the steps. - mover: a standing figure's facing turns as a planned turn (stand_turn): held TURN_LEAD (0.15 s) while the head leads, then on at most a 0.2 s half-life within what the feet let it. Turning while walking is unchanged. - character: the eyes look along the way it turns to while it turns on the spot. test_anim_pipeline turn_on_the_spot now turns 30, 90 and 180 degrees each way: 0, 2 and 4 steps (180 was 11), the head at 0.03 s, the chest at 0.05, the pelvis at 0.22 and the first foot at 0.32; the old "45 degrees a step or less" check, which rewarded the shuffle, is gone. --- src/ae3d/character/module.ae | 6 + src/ae3d/ikrig/module.ae | 288 ++++++++++++++++++++++++++++++++++- src/ae3d/mover/module.ae | 63 +++++++- tests/test_anim_pipeline.ae | 107 ++++++++++--- 4 files changed, 435 insertions(+), 29 deletions(-) diff --git a/src/ae3d/character/module.ae b/src/ae3d/character/module.ae index b9c8d8f2..f8428133 100644 --- a/src/ae3d/character/module.ae +++ b/src/ae3d/character/module.ae @@ -2906,6 +2906,12 @@ character_fixed(state: ptr, e: *Engine, dt: float) { mover.step(m, dt) } ahead = core.quat_apply(behaviour.object_rotation(o), core.vec3(0.0, 0.0, 1.0)) + // Turning on the spot, the eyes lead: along the way it is to face, the + // head, the chest and then the body following (#976). + if mover.turning_on_spot(m) { + g = mover.turn_goal(m) + ahead = core.vec3(core.sin_of(g), 0.0, core.cos_of(g)) + } eyes = core.vec3(at.x + ahead.x * LOOK_AHEAD, at.y + EYE_HIGH, at.z + ahead.z * LOOK_AHEAD) if c.looking { eyes = c.look_at } if c.aiming { eyes = c.target } diff --git a/src/ae3d/ikrig/module.ae b/src/ae3d/ikrig/module.ae index a0e4d8f6..aa79dfe4 100644 --- a/src/ae3d/ikrig/module.ae +++ b/src/ae3d/ikrig/module.ae @@ -35,7 +35,7 @@ import ae3d.ik exports ( Feet, Look, RELEASE, LOCK_SLIP, STAND_UP, feet_new, feet_free, feet_ground_physics, feet_set_lock, feet_set_weight, feet_set_upright, feet_solve, toe_local, - feet_set_steps, feet_steps, feet_stepping, feet_still, feet_miss, feet_set_stride, feet_set_raise, feet_reset, feet_stand, + feet_set_steps, feet_steps, feet_stepping, feet_turn_to, feet_turns, feet_turn_reach, feet_still, feet_miss, feet_set_stride, feet_set_raise, feet_reset, feet_stand, feet_locked, feet_drop, feet_target, feet_soles, toe_tip, soft_reach, Limb, limb_new, limb_free, leg_limb, arm_limb, limb_solve, limb_points, lift_turn, limb_span, limb_folded, limb_bend_for, limb_bend, limb_side, limb_end_twist, KNEE_MOST, ELBOW_MOST, ARM_TWIST, look_new, look_free, look_set, look_solve, look_weight, look_spine, aim_chain, @@ -126,7 +126,8 @@ const TOE_MOST = 1.4 // Turning on the spot (#827): a planted foot steps when the clip has it // turned this far (radians) or moved this far (metres) from where it is held, // over STEP_TIME seconds, lifted STEP_LIFT at the step's middle; one foot at -// a time. +// a time.

The feet keep the way round (turn_sign) while the goal is more than a right angle off, none while there is nothing to turn. - The body's yaw is its object's (the mover's facing, the goal's frame), not the rig's heel-to-toe forward, which stood off it: a 179.5 degree turn to the left read as one to the right. - Feet planted a few degrees apart are even (TURN_EVEN): read to the degree, the foot a few degrees behind went first and the other closed a few degrees to it, 8 steps for half a turn. No stance-drift step while the turn still steps (a pivoting foot is off its stance by design). - A standing figure turning to set off walks only once its feet have taken the turn's last step (ikrig.feet_turn_busy, mover.toward): let go at 10 degrees, it threw a foot 73 rad/s and crossed it 37 mm. - A character turning to a seat's slot enters it once its feet are done: a turn's step still under way skated a toe 9.8 mm as it sat. - test_humanoid's turn round asks for 4 steps or fewer, not 45 degrees or less a step (which rewarded the shuffle). --- src/ae3d/character/module.ae | 4 +- src/ae3d/ikrig/module.ae | 101 ++++++++++++++++++++++++++++------- src/ae3d/mover/module.ae | 10 +++- tests/test_humanoid.ae | 13 ++--- 4 files changed, 101 insertions(+), 27 deletions(-) diff --git a/src/ae3d/character/module.ae b/src/ae3d/character/module.ae index f8428133..f3b4e265 100644 --- a/src/ae3d/character/module.ae +++ b/src/ae3d/character/module.ae @@ -2765,7 +2765,9 @@ use_step(c: *Character, dt: float) -> bool { mover.step(m, dt) ahead = core.quat_apply(behaviour.object_rotation(o), core.vec3(0.0, 0.0, 1.0)) off = core.abs_of(wrap_angle(yaw - core.atan2_of(ahead.x, ahead.z))) - if off < FACED && c.use_t > 0.3 { + // And its feet done turning it (#976): entered with a turn's step + // still under way, its toe skated 9.8 mm as it sat. + if off < FACED && c.use_t > 0.3 && !ikrig.feet_turn_busy(c.feet as *Feet) { // Entered: the take's own root motion moves it, warped onto the slot. c.use_enter = take_state(c, usable.slot_enter(u, c.use_slot), false, usable.slot_enter_from(u, c.use_slot)) c.use_loop = take_state(c, usable.slot_loop(u, c.use_slot), true, usable.slot_loop_from(u, c.use_slot)) diff --git a/src/ae3d/ikrig/module.ae b/src/ae3d/ikrig/module.ae index aa79dfe4..3373910f 100644 --- a/src/ae3d/ikrig/module.ae +++ b/src/ae3d/ikrig/module.ae @@ -35,7 +35,7 @@ import ae3d.ik exports ( Feet, Look, RELEASE, LOCK_SLIP, STAND_UP, feet_new, feet_free, feet_ground_physics, feet_set_lock, feet_set_weight, feet_set_upright, feet_solve, toe_local, - feet_set_steps, feet_steps, feet_stepping, feet_turn_to, feet_turns, feet_turn_reach, feet_still, feet_miss, feet_set_stride, feet_set_raise, feet_reset, feet_stand, + feet_set_steps, feet_steps, feet_stepping, feet_turn_to, feet_turns, feet_turn_busy, feet_turn_reach, feet_still, feet_miss, feet_set_stride, feet_set_raise, feet_reset, feet_stand, feet_locked, feet_drop, feet_target, feet_soles, toe_tip, soft_reach, Limb, limb_new, limb_free, leg_limb, arm_limb, limb_solve, limb_points, lift_turn, limb_span, limb_folded, limb_bend_for, limb_bend, limb_side, limb_end_twist, KNEE_MOST, ELBOW_MOST, ARM_TWIST, look_new, look_free, look_set, look_solve, look_weight, look_spine, aim_chain, @@ -158,6 +158,9 @@ const TURN_ONSET = 0.2 const TURN_OPEN = 1.3 const TURN_SNAP = 0.35 const TURN_DONE = 0.05 +// Feet whose stances are this close (radians) are even: the one on the +// turn's side steps first, and neither closes to the other. +const TURN_EVEN = 0.25 const TURN_STEP_TIME = 0.34 // Radians a planted foot pivots on its toe's tip at the most while the other // steps (turn_pivot), the body turning as much further. @@ -317,10 +320,13 @@ struct Feet { upright: float // how much the trunk stands, 0 to 1: the most a foot is landed on (feet_set_upright) turn_on: bool // a turn on the spot is asked (feet_turn_to) turn_goal: float // the way the body is to face, yaw over the ground + turn_sign: float // the way round it turns: 1 to its left, -1 to its right, 0 not turning step_planned: ptr // float[2]: 1 while a step under way is a planned turn's step_land: ptr // float[2]: the way the body faces in the stance that step lands in, yaw stance_off: ptr // float[2]: each clip foot's heading off the way the body faces this frame - body_yaw: float // the way the body faced this frame, yaw over the ground + body_yaw: float // the way the body faced this frame, yaw over the ground (its object's) + yaw_off: float // how far the rig's forward stands off its object's, yaw + yaw_known: bool body_at: Vec3 // and the point it turns about (its object's), the ground's space lead: float // the trunk's lead into the turn, radians, on its spring (LEAD_SETTLE) lead_speed: float @@ -1576,7 +1582,18 @@ feet_solve(f: *Feet, rig: *pose.Rig, p: ptr, worlds: ptr, left: float, right: fl if core.v3_len(facing) > 0.000001 { facing = core.v3_normalize(facing) } // The way the body faces and the point it turns about, for a planned // turn's steps (feet_turn_to). - f.body_yaw = core.atan2_of(facing.x, facing.z) + // Its object's yaw (the mover's facing, which a turn's goal is given + // in), as drawn: the rig's forward from its heels to its toes, less how + // far that stands off the object's forward (taken once).

Its steps after the graph still run at its own turn, in order, on the main thread. Animators evaluated at the fixed step, paused ones and ones moved by root motion (their capsule moves as the graph is evaluated) keep their own turns. Each evaluation reads only its own state and the static world, so the poses are the same to the bit at any pool size and with none: test_animlod's twin streets (six walkers on a physics floor, two at slower rates) step one street on one thread and one on the pool, and every number of every pose drawn matches over 150 frames. animator.on_pool(false) evaluates them together on the calling thread: what a profile is taken on. bench_animlod measures 100 full figures (was 64) and prints the pooled frame. bench_animlod, best of five blocks on a shared machine: 100 full figures plus 2,000 in the crowd, 4.66 ms on one thread (42.6 us a figure); 1.35 ms on the pool's 24 threads, 1.77 ms on 12. --- benchmarks/bench_animlod.ae | 28 ++++++- src/ae3d/animator/module.ae | 144 +++++++++++++++++++++++++++++++++--- tests/test_animlod.ae | 106 +++++++++++++++++++++++++- 3 files changed, 263 insertions(+), 15 deletions(-) diff --git a/benchmarks/bench_animlod.ae b/benchmarks/bench_animlod.ae index 870eadc4..8f9b20f7 100644 --- a/benchmarks/bench_animlod.ae +++ b/benchmarks/bench_animlod.ae @@ -16,7 +16,14 @@ // and not counted here; // - so what 2,000 figures cost a frame: as crowd instances; with the 100 // nearest full figures (Siltreach's plan: 2 ms for 100 near and 2,000 in -// the crowd); and every one a full figure at one frame in 8. +// the crowd); and every one a full figure at one frame in 8; +// - a full figure's frame by system (animator.profile), on one thread; +// - and the 100 full figures with their animators evaluated on the +// engine's job pool (AE3D_JOBS threads, or one a hardware thread). +// +// The figures stand on a floor in a physics world: their capsules move +// them and their feet read the ground by its rays.

Each animator now evaluates in a new fixed group after the physics (engine.FIXED_POSE), posed where the step left its capsule and the ground, as the pose phase posed it on a fixed tick; set_fixed still puts it before the physics for physanim. Each group's animators go to the job pool together at the first one's turn in the step (evaluate_step_all, the pose phase's pool moved there), each pose written at its own turn on this thread. Their posts run in the pose phase. Their joints, written in the step, are drawn between their last two steps by the frame's share of the next (core.interp, #563), and pose_shown gives that same pose in the pose phase (the last two steps' poses blended). The update-rate LOD's 1 in N rates are steps.

A mirrored pose gives each side's curve to the other. test_morph now also draws the morphed, skinned column on both renderers against the CPU's morph baked in (0 channels apart), and bench_morph times the OpenGL pass with a GL_TIME_ELAPSED query. --- benchmarks/bench_morph.ae | 71 ++++++ changes/2026-11-09-morph-targets.md | 16 +- docs/pipeline.md | 14 +- src/ae3d/face/module.ae | 338 ++++++++++++++++++++++++++++ src/ae3d/gl/module.ae | 26 ++- src/ae3d/pose/module.ae | 24 +- tests/test_morph.ae | 176 ++++++++++++++- 7 files changed, 653 insertions(+), 12 deletions(-) create mode 100644 src/ae3d/face/module.ae diff --git a/benchmarks/bench_morph.ae b/benchmarks/bench_morph.ae index 0ca07c91..1416c66d 100644 --- a/benchmarks/bench_morph.ae +++ b/benchmarks/bench_morph.ae @@ -20,6 +20,8 @@ import ae3d.gltf import ae3d.morph import ae3d.platform import ae3d.vulkan +import ae3d.gl +import ae3d.offscreen const SIDE = 512 const TARGETS = 16 @@ -133,6 +135,73 @@ device(n: int) { vulkan.renderer_free(renderer) } +// The same on OpenGL: the transform-feedback pass timed by a GL_TIME_ELAPSED +// query around back-to-back morphs (gl.renderer_time_morph), each sending +// its active list as a frame does. +on_gl(n: int) { + context = offscreen.context_create(64, 64) + if context == null { + println(" skip no OpenGL context") + return + } + renderer = gl.renderer_new() + pass = gl.backend(renderer) + if !core.backend_init(&pass, context, 64, 64) { + println(" skip the OpenGL backend would not initialise") + gl.renderer_free(renderer) + offscreen.context_destroy(context) + return + } + target = offscreen.target_create(64, 64) + gl.renderer_set_target(renderer, target) + cam = core.camera_new(64, 64) + light = core.light_directional(core.vec3(0.2, 1.0, 0.3), core.vec3(1.0, 1.0, 1.0), 1.0) + m = grid() + core.backend_add_model(&pass, m) + vertices = SIDE * SIDE + ms1 = 0.0 + ms16 = 0.0 + c = 0 + while c < 3 { + k = 1 + if c == 1 { k = 4 } + if c == 2 { k = 16 } + t = 0 + while t < TARGETS { + w = 0.0 + if t < k { w = 0.5 } + core.model_set_morph_weight(m, t, w) + t = t + 1 + } + core.backend_render(&pass, cam, light) + ms = 0.0 - 1.0 + run = 0 + while run < 5 { + got = gl.renderer_time_morph(m, n) + if got >= 0.0 && (ms < 0.0 || got < ms) { ms = got } + run = run + 1 + } + each = ms / (n as float) + println(" ${k} of ${TARGETS} targets active: ${each} ms a morph of ${vertices} vertices, ${each * 1000000.0 / (vertices as float)} ns a vertex") + if k == 1 { ms1 = each } + if k == 16 { ms16 = each } + c = c + 1 + } + if ms16 > 0.0 { + slope = (ms16 - ms1) * 1000000.0 / ((vertices as float) * 15.0) + fixed = ms1 * 1000000.0 / (vertices as float) - slope + println(" a vertex costs ${slope} ns an active target, and ${fixed} ns for the pass itself") + } + core.backend_remove_model(&pass, m) + core.backend_cleanup(&pass) + core.model_free(m) + core.light_free(light) + core.camera_free(cam) + offscreen.target_destroy(target) + gl.renderer_free(renderer) + offscreen.context_destroy(context) +} + import_cost(n: int) { path = "tests/fixtures/gltf/MorphStressTest.glb" loads = n / 10 @@ -167,6 +236,8 @@ main() { println("bench_morph (#910): ${n} repeats") println("on the device (Vulkan):") device(n) + println("on the device (OpenGL):") + on_gl(n) println("import:") import_cost(n) } diff --git a/changes/2026-11-09-morph-targets.md b/changes/2026-11-09-morph-targets.md index 26af4b1c..6e141154 100644 --- a/changes/2026-11-09-morph-targets.md +++ b/changes/2026-11-09-morph-targets.md @@ -24,8 +24,18 @@ rig's poses carry them after the joints; takes sample them from a weights channel (`clips.from_scene`), blends lerp them, additives add them, and the animator inertializes them as it does the joints. -- **Measured** (`bench_morph`, RTX 4070 Ti): 0.075 to 0.096 ns a vertex an - active target on the device (262,144 vertices, 16 targets), 0.07 to 0.15 - ns a vertex for the pass itself; MorphStressTest imports in 0.76 ms. + Drawn morphed and skinned, the column's frame is the frame of the CPU's + morph baked in and skinned, 0 channels apart on both renderers.

The retargeter is held to them (`tests/test_anim_pipeline.ae`), and the blend spaces, starts, stops and turns are made from them. diff --git a/tests/fixtures/people/vroid_base_female.vrm b/tests/fixtures/people/vroid_base_female.vrm new file mode 100644 index 0000000000000000000000000000000000000000..cf4f0ccca2bfc61f8c68d8c3265f9f00f304bfe3 GIT binary patch literal 1142864 zcmeEv2Ygh;_CI1rpNfjug&D=wi|T>Cbu8MzLx)8lgF6l4_U<+!|Y znz*j1DRI3uagKrlr#CKPcw9ecp3~#-x;=3Tab5CUk0z(LZl;UZThVlo)58YD5Bhj* z+(=DauCpN9S%9&J$K^S4o%o@(Bhwk*$1wmiYU1)eu3VSbHArfb>&`+GqbAOkm*vW2 zUz#wl*XwchDfF_B!{a)2OlzCowqu951g$2nL&wyVq~y2+ohB~5RreMhJEpeG(8eX` zHF51aw(XFf#y()QZmrrr+D80jU@%E56o&9RJpG(r5yI-Rb(ptmaPvrwd|sVJ_M27l zo2~jcz1H_PJ)o={Q?FP2W{~}6RQx7`MX!KGFM~y|fJHBZ#h`%2AcMuAfW;t##h`%2 zAcMuAfW;t##h`%2AcMuIfW;_-#i)SAD1*hQfW;_-#i)SAD1*hQfW;_-#iW46B!k7I zfW;((#iW46B!k7IfW;((#iW46B!k7QfW<6>#jJqEEQ7_YfW<6>#jJqEEQ7_YfW<6> z#iD@4B7?=EfW;z%#iD@4B7?=EfW;z%#iD@4B7?=MfW<0<#j1eCDuczUfW<0<#j1eC zDuczUfW<0<#ioG8CWFPMfW;<*#ioG8CWFPMfW;<*#ioG8CWA$%RRE*Y%AnC{72xQ! zGI(@a1wcBj3?iLY0g_HDgGr}V0HxE)q0%X#(#fIHDWTHIq0%X#@{z+jB~(6=Sf_+a zCx=QYjCFEptW%0(on8)=UI~?6zE=>*P>#^09*3ZyM1|4;%8n@&QQf6vwAN}fw8FoP z)|ojONy*6>9h`;elLIX%sKkJ6lJfd_hN`w`U6`l(dpoy!|1`J9;~uO!L|UN-dYYLC z!9Z=E+ATvJRMtWbRQ9_XsOVJ%wZxC@*?x1_2?
