Additional Inherited Members

Detailed DescriptionThe 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​.

Member Function Documentation

---

void * SoGLMultiTextureMatrixElement::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 SoGLMultiTextureMatrixElement::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 SoMultiTextureMatrixElement​.

---

void SoGLMultiTextureMatrixElement::push (SoState * state) [virtual]This method is called every time a new element is required in one of the stacks​. This happens when a writable element is requested, using SoState::getElement() or indirectly SoElement::getElement(), and the depth of the current element is less than the state depth​. Override this method if your element needs to copy data from the previous top of stack​. The push() method is called on the new element, and the previous element can be found using SoElement::getNextInStack()​. Reimplemented from SoMultiTextureMatrixElement​.

---

void SoGLMultiTextureMatrixElement::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 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​.
