ModelRoot

from panda3d.core import ModelRoot
class ModelRoot

Bases: ModelNode

A node of this type is created automatically at the root of each model file that is loaded. It may eventually contain some information about the contents of the model; at the moment, it contains no special information, but can be used as a flag to indicate the presence of a loaded model file.

class ModelReference

Bases: ReferenceCount

This class is used to unify references to the same model.
