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.
SoGLVBOElement::SoGLVBOElement | ( | void | ) | [protected] |
The constructor.
SoGLVBOElement::~SoGLVBOElement | ( | ) | [protected, virtual] |
The destructor.
SoType SoGLVBOElement::getClassTypeId | ( | void | ) | [static] |
This static method returns the class type.
Reimplemented from SoElement.
int SoGLVBOElement::getClassStackIndex | ( | void | ) | [static] |
This static method returns the state stack index for the class.
Reimplemented from SoElement.
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.
Reimplemented from SoElement.
SbBool SoGLVBOElement::shouldCreateVBO | ( | SoState * | state, |
const int | numdata | ||
) | [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 int | unit, | ||
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] |
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] |
SoGLVBOElement * SoGLVBOElement::getElement | ( | SoState * | state | ) | [static, protected] |
Returns a writable element instance.
