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.

Member Function Documentation

copyMatchInfo()

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 scene graph traversal caching operations.

Implements SoElement.

createInstance()

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.

Creates a new instance of the class type corresponding to the SoType object.

getClassStackIndex()

int SoGLVBOElement::getClassStackIndex ( void )

static

This static method returns the state stack index for the class.

getClassTypeId()

SoType SoGLVBOElement::getClassTypeId ( void )

static

This static method returns the SoType object associated with objects of this class.

getElement()

SoGLVBOElement * SoGLVBOElement::getElement ( SoState * state )

staticprotected

Returns a writable element instance.

getInstance()

const SoGLVBOElement * SoGLVBOElement::getInstance ( SoState * state )

static

Returns a read-only element instance.

init()

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.

initClass()

void SoGLVBOElement::initClass ( void )

static

Initialize relevant common data for all instances, like the type system.

matches()

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.

pop()

void SoGLVBOElement::pop ( SoState * state, const SoElement * prevTopElement )

virtual

This method is called 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.

push()

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.

setColorVBO()

void SoGLVBOElement::setColorVBO ( SoState * state, SoVBO * vbo )

static

Sets the color VBO.

setNormalVBO()

void SoGLVBOElement::setNormalVBO ( SoState * state, SoVBO * vbo )

static

Sets the normal VBO.

setTexCoordVBO()

void SoGLVBOElement::setTexCoordVBO ( SoState * state, const int unit, SoVBO * vbo )

static

Sets the texture coordinate VBO.

setVertexVBO()

void SoGLVBOElement::setVertexVBO ( SoState * state, SoVBO * vbo )

static

Sets the vertex VBO.

shouldCreateVBO()

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.
