Cortex 10.5.6.0

Improvements

• IECoreGL::Selector: Added constructor overload that accepts a boolean indicating a more precise, camera-space depth sample will be used to sample depth instead of OpenGL's depth buffer.
• IECoreGL::ColorTexture: Added new constructor that accepts an argument specifying the internal storage format to use.

Cortex 10.5.5.0

Features

• PyBindConverter : Added new class providing interoperability between Boost Python bindings and PyBind11 bindings.

Improvements

• USDScene : Added basic loading of UsdGeomNurbsCurves, converting them to CurvesPrimitives.
• OStreamMessageHandler : Added level prefix to every line.

Fixes

• CompoundObject : Fixed crashes in Python bindings caused by passing None as a key.
• VDBObject : Fixed Python bindings for OpenVDB 10.1.

Cortex 10.5.4.2

Fixes

• ExceptionAlgo : Fixed memory leak in translatePythonException(), which was failing to manage the reference count for exceptions bound by IECorePython::ExceptionClass.

Cortex 10.5.4.1

Fixes

• OpenImageIOAlgo : Properly handle empty metadata values.

Cortex 10.5.4.0

Improvements

• ShaderNetwork : Added support for InternedStringData attributes in string parameter substitutions.
• MurmurHash : Added specialisation for std::hash, among other things allowing the use of MurmurHash as a key in unordered_map.
• CompoundObject : Defaulted template argument to Object in member() methods.

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
