PipeOcclusionCullTraverser

from panda3d.core import PipeOcclusionCullTraverser
class PipeOcclusionCullTraverser

Bases: CullTraverser

This specialization of CullTraverser uses the graphics pipe itself to perform occlusion culling. As such, it’s likely to be inefficient (since it interferes with the pipe’s normal mode of rendering), and is mainly useful to test other, CPU-based occlusion algorithms.

This cannot be used in a multithreaded pipeline environment where cull and draw are operating simultaneously.

It can’t be defined in the cull subdirectory, because it needs access to GraphicsPipe and DisplayRegion and other classes in display. So we put it in grutil instead, for lack of any better ideas.
