Cortex 10.7.0.0a11

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.
