Cortex 10.4.7.0

Improvements

• IECoreGL::PointsPrimitive : Added renderUsesGLPoints() method (#1347).
• IECoreGL::CurvesPrimitive : Added renderUsesGLLines() method (#1347).
• StringAlgo : Added concat() and toInt() methods (#1343).
• IECoreScene::ShaderNetworkAlgo (#1343) :
  • Added convertToOSLConventions(), expandSplines() and collapseSplines().
  • Deprecated convertOSLComponentConnections(), expandSplineParameters() and collapseSplineParameters().
• USDScene : Added support for roundtripping connections to SplineData parameters.

Fixes

• IECoreUSD::PrimitiveAlgo (#1346) :
  • Fixed reading of primitives containing primvars:normals. These are now correctly loaded as a primitive variable called N, taking precedence over the UsdGeomPointBased normals attribute.
  • Fixed writing of indexed normals so that the indexing is retained on load. Note that this means that normals are now always written as primvars:normals and never via the UsdGeomPointBased normals attribute.

Cortex 10.4.6.0

Features

• MeshAlgo : Added new MeshSplitter class, for efficient splitting meshes based on uniform primitive variables.
• ImathHash : Added new header that defines std::hash for Imath types.

Improvements

• PointsPrimitive, Primitive : Accelerated bounds computation using tbb::parallel_reduce.
• MeshAlgo : Improved performance of segment().

Fixes

• ImageReader : Fixed compilation with versions of OIIO < 2.4.
• USDScene : Invalid primitive variables are now skipped during loading, with a warning being emitted instead.
• MeshAlgo : Fixed crease handling in deleteFaces().

Build

• Updated CI builds to use GafferHQ/dependencies version 6.0.0, making them suitable for use in Gaffer 1.2.x.x.

Cortex 10.4.5.0

Improvements

• CurvesAlgo, MeshAlgo, PointsAlgo : resamplePrimitiveVariable() now supports all data types when resampling a Constant primitive variable.

Build

• Update Windows release build dependencies to 6.2.1.
• Added compatibility with OpenImageIO 2.4.

Cortex 10.4.4.0

Improvements

• USD :
  • Added loading of float4 USD shader parameters as Color4 parameters.
  • Added support for Arnold-USD's convention for representing connections to individual indices of an array.

Build

• Added compatibility with USD 23.02.
• Updated Windows dependencies to 6.2.1.

Cortex 10.4.3.1

Fixes

• IECoreMaya.SceneShapeSubSceneOverride : Visibility override fixes (#1320).
  • Removed SceneInterface visibility check, as it is now obsolete and causing issues.
  • Check visibility for root locations, so bounds aren't incorrectly drawn.
• VDBObject : Fixed infinite recursion in isEqualTo() (#1314).

Cortex 10.3.8.1

Fixes

• IECoreMaya.SceneShapeSubSceneOverride : Visibility override fixes (#1320).
  • Removed SceneInterface visibility check, as it is now obsolete and causing issues.
  • Check visibility for root locations, so bounds aren't incorrectly drawn.

Cortex 10.4.3.0

Features

• IECoreNuke : Add LiveScene support for Nuke (#1310).
  • LiveSceneKnob : Knob to interface with LiveScene from Python.
  • LiveSceneHolder : Node to hold LiveSceneKnob to provide a Python interface with LiveScene.
• IECoreMaya : Add non-drawable ieSceneShapeProxy subclassed from ieSceneShape (#1311).

Improvements

• Added string constructor and static fromString function to IECore.MurmurHash.

Fixes

• IECoreUSD : Fixed error in pluginfo.json preventing USD on Windows from loading IECoreUSD.dll.
• IECoreScene : Fixed MeshPrimitiveEvaluator assert typo.

Build

• Updated Windows dependencies to 6.2.0.
• Added WITH_OIIO_UTIL option.

Cortex 10.3.8.0

Features

• IECoreNuke : Add LiveScene support for Nuke (#1310).
  • LiveSceneKnob : Knob to interface with LiveScene from Python.
  • LiveSceneHolder : Node to hold LiveSceneKnob to provide a Python interface with LiveScene.
• IECoreMaya : Add non-drawable ieSceneShapeProxy subclassed from ieSceneShape (#1311).

Fixes

• IECoreUSD : Fixed error in pluginfo.json preventing USD on Windows from loading IECoreUSD.dll.

Cortex 10.4.2.1

Build

• Added Windows package to build artifacts and release binaries.

Cortex 10.4.2.0

Improvements

• AlembicScene : Added support for unsigned char, uint16, int16 and uint32 GeomParams, mapping them to and from
  UCharVectorData, UShortVectorData, ShortVectorData and UIntVectorData PrimitiveVariables respectively (#1297).
• CubicBasis (#1298) :
  • Added Constant standard basis, for performing stepped interpolation.
  • Bound numCoefficients() method to Python.
• ShaderNetworkAlgo : Added support for spline parameters with Constant basis. These are mapped to the constant interpolation type in OSL (#1298).

Fixes
