CullResult

from panda3d.core import CullResult
class CullResult

Bases: ReferenceCount

This stores the result of a BinCullHandler traversal: an ordered collection of CullBins, each of which holds a number of Geoms and RenderStates to be rendered in some defined order.

This is also used to keep the results of last frame’s cull traversal around to make next frame’s traversal of the same scene a little easier.
