| HDST_API void | SetEnableTinyPrimCulling (bool tinyPrimCulling) |
A buffer of commands (HdStDrawItem or HdComputeItem objects) to be executed.
The HdStCommandBuffer is responsible for accumulating draw items and sorting them for correctness (e.g. alpha transparency) and efficiency (e.g. the fewest number of GPU state changes).

Execute the command buffer.
| HDST_API void FrustumCull | ( | GfMatrix4d const & | cullMatrix | ) |
Cull drawItemInstances based on passed in combined view and projection matrix.
