CullTraverserData
from panda3d.core import CullTraverserData
- class CullTraverserData
Bases:
DTOOL_SUPER_BASEThis collects together the pieces of data that are accumulated for each node while walking the scene graph during the cull traversal.
Having this as a separate object simplifies the parameter list to CullTraverser::r_traverse(), as well as to other functions like PandaNode::cull_callback(). It also makes it easier to add cull parameters, and provides a place to abstract out some of the cull behavior (like view-frustum culling).
