Cortex 10.5.3.0

Improvements

• OpenImageIOAlgo : Added support for InternedStringVectorData to DataView.

Build

• Windows : Fixed include order.

Cortex 10.5.2.1

Build

• SConstruct : Make sure VDB includes can be found
• USDScene : Fix build for older USD versions

Cortex 10.5.2.0

Improvements

• USD PrimitiveAlgo : Added readPrimitiveVariable() utility method for reading from regular UsdAttributes.
• USDScene : Added support for reading from in-memory stages by passing a filename of the form stageCache:{id}.usd where {id} specifies a stage which has been inserted in the UsdUtilsStageCache.

Fixes

• USDScene :
  • Fixed handling of invalid values on the following attributes :
    • PointBased : positions, normals, velocities, accelerations.
    • Curves : widths.
    • PointInstancer : ids, protoIndices, orientations, scales, velocities, accelerations, angularVelocities.
    • Points : ids, widths.
      Invalid values are now ignored with a warning, instead of loading as invalid primitive variables.
  • Fixed treatment of unconnected material outputs during reading. If they were "authored" but not connected to a source, they were incorrectly being treated as valid attributes, and loading as empty ShaderNetworks which caused problems elsewhere.
• ToMayaMeshConverter : No longer locks normals set on the Mesh from the scc.

Breaking Changes

• IECoreMaya : Maya meshes converted from Cortex data no longer have normals set explicitly and instead relies on Maya to calculate them.

Cortex 10.4.10.3

Fixes

• USDScene : Fixed treatment of unconnected material outputs during reading. If they were "authored" but not connected to a source, they were incorrectly being treated as valid attributes, and loading as empty ShaderNetworks which caused problems elsewhere.

Cortex 10.5.1.0

Improvements

• USDScene : Added limited support for reading and writing Volume prims via IECoreVDB::VDBObject.

Fixes

• USDScene : Fixed writing of lights so they are represented as appropriate UsdLux*Light prims in USD.
• FrameRange : Prevented creation of FrameRanges with negative steps
• IECore.dataTypeFromElement : Fixed support for list to Vector conversions
• LinkedScene : Fixed bug where linkLocations attribute was baked incorrectly if the link target location wasn't the ROOT
  • This in turn caused LinkedScene::setNames() and LinkedScene::readSet() to error
• IECoreNuke::FromNukePointsConverter : Use Color3f instead of Color4f to be compatible with Gaffer
• IECoreNuke::SceneCacheReader : Fixed crash with SceneCacheReader when widget updates while Caribou updates

Cortex 10.4.10.2

Fixes

• LinkedScene : Fixed bug where linkLocations attribute was baked incorrectly if the link target location wasn't the ROOT
  • This in turn caused LinkedScene::setNames() and LinkedScene::readSet() to error
• IECoreNuke::FromNukePointsConverter : Use Color3f instead of Color4f to be compatible with Gaffer
• IECoreNuke::SceneCacheReader : Fixed crash with SceneCacheReader when widget updates while Caribou updates

Cortex 10.4.10.1

Fixes

• FrameRange : Prevented creation of FrameRanges with negative steps
• IECore.dataTypeFromElement : Fixed support for list to Vector conversions

Cortex 10.5.0.0

Features

• MeshAlgo :
  • Added new algorithms for computing mesh normals : calculateUniformNormals(), calculateVertexNormals() and calculateFaceVaryingNormals().
  • Added correspondingFaceVertices() method.

Improvements

• MeshAlgo distributePoints() :
  • Added support for density primitive variable values above 1.
  • Added sampling of arbitrary primitive variables via the new primitiveVariables parameter.
  • Improved accuracy.
  • Improved performance.
• MeshAlgo triangulate() : Improved performance.
• MeshAlgo connectedVertices() : Improved performance.

Fixes

• MeshAlgo distributePoints() :
  • Fixed duplicate points at triangle edges.
  • Fixed handling of points exactly at the density threshold.
• TriangleAlgo :
  • triangleClosestBarycentric() : Fixed numerical precision bug.
  • triangleContainsPoint() : Fixed handling of zero-area triangles.
• PolygonVertexIterator : Fixed to use std::iterator_traits so that raw pointers are supported.

Breaking Changes

• IECoreAppleseed : Removed. With Appleseed's removal from Gaffer 1.3.0.0 Cortex no longer provides IECoreAppleseed.
• Python : Removed support for Python 2.
• Primitive : Changed variableIndexedView() return type from boost::optional to std::optional.
• MeshAlgo distributePoints() :
  • Changed function signature.
  • Bug fixes mean subtle changes to the resulting points.

Cortex 10.4.10.0

Improvements

• IECoreNuke::LiveScene :
  • Adding caching to speed up querying Nuke's GeometryList for large hierarchy
  • Support for ParticleSprite
  • setOp method to avoid re creating LiveScene from scratch

Fixes

• IECoreMaya.SceneShape : Fixed reading of time samples for expanded link locations
  • Traverse the time plug connections to check for a maya global time connection
• CheckedGILRelease : Safe to call if thread doesn't hold the GIL
• IECoreNuke::SceneCacheReader : release GIL during _validate to avoid crash with Caribou
• IECoreNuke::LiveScene :
  • Fix crash when there is not input GeoOp.
  • Fix uninitialized bounds
  • Fix bug with duplicated parents
  • Fix bug when querying children combined between multiple parents

Cortex 10.4.9.1

Fixes

• USDScene : Fixed hash clashes when the same USD file containing instanceable prims was opened a second time. Because USD doesn't assign prototypes deterministically, hashes would be shuffled between prototypes, yielding inconsistencies between the hashes for the two scenes. Hashes are now completely unique from scene-to-scene, so no locations can have clashing hashes.
