OccluderNode

from panda3d.core import OccluderNode
class OccluderNode

Bases: PandaNode

A node in the scene graph that can hold an occluder polygon, which must be a rectangle. When the occluder is activated with something like render.set_occluder(), then objects whose bouding volume lies entirely behind the occluder will not be rendered.
