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. More...

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

This function initializes the element type in the given SoState. It is called for the first element of each enabled element type in SoState objects.
Reimplemented from SoTextureMatrixElement.
This method is callled when the state is popped, and the depth of the element is bigger than the current state depth. pop() is called on the new top of stack, and a pointer to the previous top of stack is passed in prevTopElement.
Override this method if you need to copy some state information from the previous top of stack.
Reimplemented from SoElement.

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.
|
virtual |
virtual method which is called from makeIdentity(). Sets element matrix to identity.
Reimplemented from SoTextureMatrixElement.
|
virtual |
virtual method which is called from mult(). Multiplies matrix into element matrix.
Reimplemented from SoTextureMatrixElement.
|
virtual |
virtual method which is called from translateBy(). Appends translation to the element matrix.
Reimplemented from SoTextureMatrixElement.
|
virtual |
virtual method which is called from rotateBy(). Appends rotation to the element matrix.
Reimplemented from SoTextureMatrixElement.
|
virtual |
virtual method which is called from scaleBy(). Append scaleFactor to the element matrix.
Reimplemented from SoTextureMatrixElement.
