SoGLMultiTextureMatrixElement

NAME

SoGLMultiTextureMatrixElement -

The SoGLMultiTextureMatrixElement class is used to update the OpenGL texture matrix.

Since (for some weird reason) most OpenGL implementations have a very small texture matrix stack, and since the matrix stack also is broken on many OpenGL implementations, the texture matrix is always loaded into OpenGL. We do not push() and pop() matrices.

SYNOPSIS

#include <Inventor/elements/SoGLMultiTextureMatrixElement.h>

Inherits SoMultiTextureMatrixElement.
