Gaffer 1.7.0.0a11

Features

• PointInstancer : Added class to provide first-class encoding of point instancers.

Improvements

• PrimitiveVariable : Added Python bindings for IndexedView class.
• USDScene :
  • Added support for writing IECoreScene::PointInstancer as UsdGeomPointInstancer.
  • Added support for reading and writing mesh lights.

Fixes

• RunTimeTyped : Fixed unnecessary overhead of runTimeCast() and isInstanceOf() for subclasses implemented in Python. The GIL is now never needed when the cast is to a C++ type.
• PrimitiveVariable : Made IndexedView begin() and end() const.
• PointsAlgo :
  • Fixed loss of blind data in deletePoints().
  • Fixed loss of primitive type in deletePoints() (if processing a derived class of PointsPrimitive).
• IECoreGL::Shader : Restored compatibility with OpenGL 2.1 in order to preserve macOS support ¹.

Breaking Changes

• ClassParameter, ClassVectorParameter : Replaced statically allocated TypeIds with ids allocated dynamically by IECore.registerRunTimeTyped(). If the id is needed from C++, it can be queried at runtime with RunTimeTyped::typeIdFromTypeName().
• RunTimeTyped : Removed typId argument from registerRunTimeTyped() Python function. TypeIds are now always allocated dynamically for Python classes.
• USD :
  • Removed support for IECOREUSD_POINTINSTANCER_RELATIVE_PROTOTYPES environment variable. Prototype paths are now always specified as relative where possible.
  • Removed ./ prefix from relative prototype paths.
  • UsdGeomPointInstancer inactiveIds are now merged into the invisibleIds primitive variable on loading, instead of being loaded separately.

Build

• CI : Updated to GafferHQ/dependencies 11.0.0a8.

Cortex 10.5.17.0

Improvements

• IECoreNuke::SceneCacheReader : Added support for writing attributes
• IECoreNuke::LiveScene : Added support for reading attributes

Cortex 10.5.16.1

Fixes

• IECoreNuke.LiveScene : Fixed point clouds from DeepToPoints to be supported. The geometry was incorrectly treated as a mesh instead of points.

Cortex 10.7.0.0a10

Features

• NanobindConverter : Added new class providing interoperability between Boost Python bindings and Nanobind bindings.

Fixes

• VDBObject : Fixed Python bindings for OpenVDB 12.

Breaking Changes

• VDBObject : Removed support for OpenVDB 10.0 and earlier.

Cortex 10.7.0.0a9

Improvements

• USDScene : Added loading of ArnoldProcedural prims as Cortex ExternalProcedural objects ¹.

Fixes

• USDScene : Fixed writing of animated camera parameters ¹.

Cortex 10.6.5.0

Improvements

• USDScene : Added loading of ArnoldProcedural prims as Cortex ExternalProcedural objects.

Fixes

• USDScene : Fixed writing of animated camera parameters.

Cortex 10.7.0.0a8

Improvements

• CurvesPrimitive :
  • Added Wrap enum, with Periodic, NonPeriodic and Pinned. This generalises the previous periodic boolean property.
  • Added argument names to variableSize() and numSegments() Python bindings, so they can be passed as keywords.
• USDScene : Added support for pinned curves.
• CurvesAlgo : Added isPinned() and convertPinnedToNonPeriodic() utilities.

Fixes

• CurvesAlgo : Fixed handling of periodic curves in deleteCurves().
• CurvesAlgo : Fixed resamplePrimitiveVariable() to handle Vertex<->Varying conversion for linear curves correctly.

Breaking Changes

• CurvesPrimitive : Made protected members private.

Cortex 10.7.0.0a7

API

• Primitive : Added default type to templated function variableData.

Breaking Changes

• HenyeyGreenstein.h : Removed.
• SweepAndPrune.h : Removed.
• RadixSort.h : Removed.

Build

• Added compatibility with USD 25.11 and 26.03.
• CI : Updated to GafferHQ/dependencies 11.0.0a3.

Cortex 10.7.0.0a6

Fixes

• CompoundData : Fixed bad formatting of exception messages ¹.

Breaking Changes

• MessageHandler : Removed support for passing boost::format objects to msg(). Use fmt::format() instead.
• FileSequence : Removed fileNameTemplate() protected method. Use fileNameForFrame() instead.

Cortex 10.7.0.0a5

Improvements

• Canceller :
  • Derived from RefCounted, to allow Cancellers to be shared between multiple clients.
  • Enabled chaining of Cancellers, via addChild() and removeChild() methods and a ScopedChild utility class.
• MessageHandler : Added msg() overload that accepts a fmt::format_string and arguments.
• InternedString : Added specialisation for fmt::formatter<InternedString>.

Breaking Changes

• Canceller : Changed base class.

Build

• Requires fmt 9.1.0.
• Removed unnecessary linking of boost_chrono.
