TransformBlendTable

from panda3d.core import TransformBlendTable
class TransformBlendTable

Bases: CopyOnWriteObject

This structure collects together the different combinations of transforms and blend amounts used by a GeomVertexData, to facilitate computing dynamic vertices on the CPU at runtime. Each vertex has a pointer to exactly one of the entries in this table, and each entry defines a number of transform/blend combinations.

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