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.
