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

Member Function Documentation

   void SoGLMultiTextureMatrixElement::initClass (void) [static] Initialize
       relevant common data for all instances, like the type system.
       Reimplemented from SoMultiTextureMatrixElement.

   void SoGLMultiTextureMatrixElement::multElt (const int unit, const SbMatrix
       & matrix) [virtual] virtual method which is called from mult().
       Multiplies matrix into element matrix.
       Reimplemented from SoMultiTextureMatrixElement.

   void SoGLMultiTextureMatrixElement::setElt (const int unit, const SbMatrix
       & matrix) [virtual] virtual method which is called from set(). Sets
       matrix intp element matrix.
       Reimplemented from SoMultiTextureMatrixElement.
