from panda3d.core import NodeVertexTransform
VertexTransformgets its matrix from the Transform stored on a node. It can also compose its node’s transform with another
VertexTransform, allowing you to build up a chain of NodeVertexTransforms that represent a list of composed matrices.
getPrev() → VertexTransform¶
VertexTransformobject whose matrix will be composed with the result of this node’s transform.
