Description

Returns the traversable handle at a specific index in the transform path.

Signature

uint64_t GetTransformListHandle(uint index);

Parameters

index : uint

Index in the transform list (0 = root, GetTransformListSize()-1 = closest to primitive)

Return value

Traversable handle at the specified index

Remarks

Currently only supported on CUDA/OptiX. Can only be called from intersection, any-hit, or closest-hit programs.
