Detailed Description

       The SoGLVBOElement class is used to store VBO state.

       FIXME: write doc.

       Be aware that this class is an extension for Coin, and it is not available in the original
       SGI Open Inventor v2.1 API.

       Since:
           Coin 2.5

Member Function Documentation

   void * SoGLVBOElement::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 SoGLVBOElement::initClass (void) [static]
       This static method initializes static data for the SoMultiTextureCoordinateElement class.

   SbBool SoGLVBOElement::shouldCreateVBO (SoState *state, const intnumdata) [static]
       Returns TRUE if VBO is supported for the current context, and if numdata is between the
       limits set for VBO rendering.

   void SoGLVBOElement::setVertexVBO (SoState *state, SoVBO *vbo) [static]
       Sets the vertex VBO.

   void SoGLVBOElement::setNormalVBO (SoState *state, SoVBO *vbo) [static]
       Sets the normal VBO.

   void SoGLVBOElement::setColorVBO (SoState *state, SoVBO *vbo) [static]
       Sets the color VBO.

   void SoGLVBOElement::setTexCoordVBO (SoState *state, const intunit, SoVBO *vbo) [static]
       Sets the texture coordinate VBO.

   const SoGLVBOElement * SoGLVBOElement::getInstance (SoState *state) [static]
       Returns a read-only element instance.

   void SoGLVBOElement::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 SoElement.

   void SoGLVBOElement::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 SoElement.

   void SoGLVBOElement::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.

   SbBool SoGLVBOElement::matches (const SoElement *element) const [virtual]
       This function returns TRUE is the element matches another element (of the same class),
       with respect to cache validity.

       If the application programmer's extension element has a matches() function, it should also
       have a copyMatchInfo() function.

       Implements SoElement.

   SoElement * SoGLVBOElement::copyMatchInfo (void) const [virtual]
       This function creates a copy of the element that contains enough information to enable the
       matches() function to work.

       Used to help with scenegraph traversal caching operations.

       Implements SoElement.

   SoGLVBOElement * SoGLVBOElement::getElement (SoState *state) [static],  [protected]
       Returns a writable element instance.
