.SH NAME
SoGLTextureMatrixElement \- 
.PP
The \fBSoGLTextureMatrixElement\fP class is used to update the OpenGL texture matrix\&.
.PP
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 \fBpush()\fP and \fBpop()\fP matrices\&.

.PP 
The \fBSoGLTextureMatrixElement\fP class is used to update the OpenGL texture matrix\&.
.PP
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 \fBpush()\fP and \fBpop()\fP matrices\&.

.SH "Member Function Documentation"
.PP 
.SS "\fBSoType\fP SoGLTextureMatrixElement::getClassTypeId (void)\fC [static]\fP"
This static method returns the class type\&. 
.PP
Reimplemented from \fBSoTextureMatrixElement\fP\&.
.SS "int SoGLTextureMatrixElement::getClassStackIndex (void)\fC [static]\fP"
This static method returns the state stack index for the class\&. 
.PP
Reimplemented from \fBSoTextureMatrixElement\fP\&.
.SS "void * SoGLTextureMatrixElement::createInstance (void)\fC [static]\fP"
\fIThis API member is considered internal to the library, as it is not likely to be of interest to the application programmer\&.\fP 
.PP
Reimplemented from \fBSoTextureMatrixElement\fP\&.
.SS "void SoGLTextureMatrixElement::initClass (void)\fC [static]\fP"
Initialize relevant common data for all instances, like the type system\&. 
.PP
Reimplemented from \fBSoTextureMatrixElement\fP\&.
.SS "void SoGLTextureMatrixElement::init (\fBSoState\fP *state)\fC [virtual]\fP"
This function initializes the element type in the given \fBSoState\fP\&. It is called for the first element of each enabled element type in \fBSoState\fP objects\&. 
.PP
Reimplemented from \fBSoTextureMatrixElement\fP\&.
.SS "void SoGLTextureMatrixElement::pop (\fBSoState\fP *state, const \fBSoElement\fP *prevTopElement)\fC [virtual]\fP"
This method is callled when the state is popped, and the depth of the element is bigger than the current state depth\&. \fBpop()\fP is called on the new top of stack, and a pointer to the previous top of stack is passed in \fIprevTopElement\fP\&.
.PP
Override this method if you need to copy some state information from the previous top of stack\&. 
.PP
Reimplemented from \fBSoElement\fP\&.
.SS "void SoGLTextureMatrixElement::setElt (const \fBSbMatrix\fP &matrix)\fC [virtual]\fP"
virtual method which is called from \fBset()\fP\&. Sets the texture matrix to \fImatrix\fP\&.
.PP
This method is an extension versus the Open Inventor API\&. 
.PP
Reimplemented from \fBSoTextureMatrixElement\fP\&.
.SS "void SoGLTextureMatrixElement::makeEltIdentity (void)\fC [virtual]\fP"
virtual method which is called from \fBmakeIdentity()\fP\&. Sets element matrix to identity\&. 
.PP
Reimplemented from \fBSoTextureMatrixElement\fP\&.
.SS "void SoGLTextureMatrixElement::multElt (const \fBSbMatrix\fP &matrix)\fC [virtual]\fP"
virtual method which is called from \fBmult()\fP\&. Multiplies \fImatrix\fP into element matrix\&. 
.PP
Reimplemented from \fBSoTextureMatrixElement\fP\&.
.SS "void SoGLTextureMatrixElement::translateEltBy (const \fBSbVec3f\fP &translation)\fC [virtual]\fP"
virtual method which is called from \fBtranslateBy()\fP\&. Appends \fItranslation\fP to the element matrix\&. 
.PP
Reimplemented from \fBSoTextureMatrixElement\fP\&.
.SS "void SoGLTextureMatrixElement::rotateEltBy (const \fBSbRotation\fP &rotation)\fC [virtual]\fP"
virtual method which is called from \fBrotateBy()\fP\&. Appends \fIrotation\fP to the element matrix\&. 
.PP
Reimplemented from \fBSoTextureMatrixElement\fP\&.
