SoTextureMatrixElement

NAME

SoTextureMatrixElement -

The SoTextureMatrixElement class is used to manage the texture matrix stack.

The texture matrix is used to transform texture coordinates before being used to map textures onto polygons.

SYNOPSIS

#include <Inventor/elements/SoTextureMatrixElement.h>

Inherits SoAccumulatedElement.

Inherited by SoGLTextureMatrixElement.
