TransformTable

from panda3d.core import TransformTable
class TransformTable

Bases: TypedWritableReferenceCount

Stores the total set of VertexTransforms that the vertices in a particular GeomVertexData object might depend on.

This structure is used for a GeomVertexData set up to compute its dynamic vertices on the graphics card. See TransformBlendTable for one set up to compute its dynamic vertices on the CPU.
