Detailed DescriptionThe 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​.

Member Function Documentation

---

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​.

---

void SoGLTextureMatrixElement::init (SoState * state) [virtual]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​.

---

void SoGLTextureMatrixElement::pop (SoState * state, const SoElement * prevTopElement) [virtual]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​.

---

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​.
