Cortex 10.7.0.0

Features

• PointInstancer : Added class to provide first-class encoding of point instancers.
• NanobindConverter : Added new class providing interoperability between Boost Python bindings and Nanobind bindings.

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.
  • Added support for pinned curves.
• 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.
• CurvesAlgo : Added isPinned() and convertPinnedToNonPeriodic() utilities.
• Primitive : Added default type to variableData() template method.
• 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>.
• TBB : Improved compatibility with oneTBB 2021.
• Ramp : Added Rampff, RampfColor3f, RampfColor4f and corresponding Ramp*Data classes, for representing user facing shader ramp parameters.

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).
• CurvesAlgo :
  • Fixed handling of periodic curves in deleteCurves().
  • Fixed resamplePrimitiveVariable() to handle Vertex<->Varying conversion for linear curves correctly.
• VDBObject : Fixed Python bindings for OpenVDB 12.

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.
• VDBObject : Removed support for OpenVDB 10.0 and earlier.
• CurvesPrimitive : Made protected members private.
• HenyeyGreenstein.h : Removed.
• SweepAndPrune.h : Removed.
• RadixSort.h : Removed.
• MessageHandler : Removed support for passing boost::format objects to msg(). Use fmt::format() instead.
• FileSequence : Removed fileNameTemplate() protected method. Use fileNameForFrame() instead.
• Canceller : Changed base class.
• IECore : Removed tbb_task_scheduler_init() Python Context Manager. Use tbb_global_control() instead.
• ShaderNetworkAlgo :
  • Removed deprecated componentConnectionAdapterLabel(), convertOSLComponentConnections(), collapseSplineParameters(), expandSplineParameters() methods.
  • Switched support for Spline parameters to support for Ramp parameters.

Build

• LibFormat : Added new dependency on fmt 9.1.0.
• CI :
  • Updated to GafferHQ/dependencies 11.0.0a8.
  • Build artifacts and releases now include a "-platform##" suffix denoting their target VFX Reference Platform year. This replaces the "gcc" suffix previously used on Linux builds.
• USD : Added compatibility with USD 25.11 and 26.03.
• Boost : Removed unnecessary linking of boost_chrono.

Cortex 10.7.0.0a14

Fixes

• USDScene :
  • Fixed bug writing shader assignments with IECOREUSD_WRITE_CONFORMANT_RENDERMAN_ATTRIBUTES=1 ¹.
  • Fixed bug reading shader assignments with IECOREUSD_WRITE_CONFORMANT_RENDERMAN_ATTRIBUTES=1 ¹.
  • Fixed bug reading legacy attributes with IECOREUSD_WRITE_CONFORMANT_RENDERMAN_ATTRIBUTES=1 ¹.

Cortex 10.6.7.1

Fixes

• USDScene :
  • Fixed bug writing shader assignments with IECOREUSD_WRITE_CONFORMANT_RENDERMAN_ATTRIBUTES=1.
  • Fixed bug reading shader assignments with IECOREUSD_WRITE_CONFORMANT_RENDERMAN_ATTRIBUTES=1.
  • Fixed bug reading legacy attributes with IECOREUSD_WRITE_CONFORMANT_RENDERMAN_ATTRIBUTES=1.

Cortex 10.7.0.0a13

Improvements

• USDScene : Added IECOREUSD_WRITE_CONFORMANT_RENDERMAN_ATTRIBUTES environment variable. If set to a value of 1, this causes "ri:" prefixed attributes to be written as expected by usdRiPxr ¹.

Fixes

• PointInstancer : Fixed signature for setPrototypes() function.

Improvements

Cortex 10.7.0.0a12

Improvements

• USDScene : Added IECOREUSD_WRITE_CONFORMANT_OSL_SHADERS environment variable. If set to a value of 1, this causes OSL shaders to be written in the format expected by RenderMan. Set the RMAN_SHADERPATH environment variable appropriately to ensure RenderMan can find the shaders ¹.
