NAME
SoGLTextureMatrixElement - The SoGLTextureMatrixElement 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/SoGLTextureMatrixElement.h>
Inherits SoTextureMatrixElement.

The destructor.
Member Function Documentation
SoType SoGLTextureMatrixElement::getClassTypeId (void) [static]
This static method returns the class type.
Reimplemented from SoTextureMatrixElement.
int SoGLTextureMatrixElement::getClassStackIndex (void) [static]
This static method returns the state stack index for the class.
Reimplemented from SoTextureMatrixElement.
void * SoGLTextureMatrixElement::createInstance (void) [static]
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
Reimplemented from SoTextureMatrixElement.
void SoGLTextureMatrixElement::initClass (void) [static]
Initialize relevant common data for all instances, like the type system.
Reimplemented from SoTextureMatrixElement.
void SoGLTextureMatrixElement::setElt (const SbMatrix & matrix) [virtual]
virtual method which is called from set(). Sets the texture matrix to matrix.
This method is an extension versus the Open Inventor API.
Reimplemented from SoTextureMatrixElement.
void SoGLTextureMatrixElement::makeEltIdentity (void) [virtual]
virtual method which is called from makeIdentity(). Sets element matrix to identity.
Reimplemented from SoTextureMatrixElement.
void SoGLTextureMatrixElement::multElt (const SbMatrix & matrix) [virtual]
virtual method which is called from mult(). Multiplies matrix into element matrix.
Reimplemented from SoTextureMatrixElement.
void SoGLTextureMatrixElement::translateEltBy (const SbVec3f & translation) [virtual]
virtual method which is called from translateBy(). Appends translation to the element matrix.
Reimplemented from SoTextureMatrixElement.
void SoGLTextureMatrixElement::rotateEltBy (const SbRotation & rotation) [virtual]
virtual method which is called from rotateBy(). Appends rotation to the element matrix.
Reimplemented from SoTextureMatrixElement.
void SoGLTextureMatrixElement::scaleEltBy (const SbVec3f & scaleFactor) [virtual]
virtual method which is called from scaleBy(). Append scaleFactor to the element matrix.
Reimplemented from SoTextureMatrixElement.
