Constructor & Destructor Documentation

◆ HdStExtComputation()

HDST_API HdStExtComputation ( SdfPath const &  id)

Construct a new ExtComputation identified by id.

Member Function Documentation

◆ Finalize()

HDST_API void Finalize ( HdRenderParam renderParam)
overridevirtual

Finalizes object resources.

This function might not delete resources, but it should deal with resource ownership so that the sprim is deletable.

Reimplemented from HdSprim.

◆ Sync()

HDST_API void Sync ( HdSceneDelegate sceneDelegate,
HdRenderParam renderParam,
HdDirtyBits *  dirtyBits 
)
overridevirtual

Synchronizes state from the delegate to this object.

Parameters
[in,out]dirtyBitsOn input specifies which state is is dirty and can be pulled from the scene delegate. On output specifies which bits are still dirty and were not cleaned by the sync.

Reimplemented from HdExtComputation.
