VertexTransform
from panda3d.core import VertexTransform
- class VertexTransform
Bases:
TypedWritableReferenceCountThis is an abstract base class that holds a pointer to some transform, computed in some arbitrary way, that is to be applied to vertices during rendering. This is used to implement soft-skinned and animated vertices. Derived classes will define how the transform is actually computed.

Geom::get_modified(), but it is in a different space.
