copyMatchInfo()

SoElement * SoGLVBOElement::copyMatchInfo ( ) const

virtual

Implements SoElement.

getInstance()

static

getVBO()

SoVBO * SoGLVBOElement::getVBO

(

VBOType

type

)

const

init()

virtual void SoGLVBOElement::init ( SoState *  state )

virtual

Called for first element of its kind in stack. Default method does nothing.

Reimplemented from SoElement.

initClass()

static void SoGLVBOElement::initClass ( )

static

matches()

bool SoGLVBOElement::matches ( const SoElement *  elt ) const

virtual

If you write a matches() method, you must also write a copy() method.

Implements SoElement.

pop()

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

virtual

Reimplemented from SoElement.

push()

virtual void SoGLVBOElement::push ( SoState *  state )

virtual

Allows for side effects to occur. Default methods do nothing.

Reimplemented from SoElement.

unsetVBO()

static void SoGLVBOElement::unsetVBO ( SoState *  state, VBOType  type  )

static

unsetVBOIfEnabled()

static void SoGLVBOElement::unsetVBOIfEnabled ( SoState *  state, VBOType  type  )

static

updateVBO()

static void SoGLVBOElement::updateVBO ( SoState *  state, VBOType  type, SoVBO **  vbo, int  numBytes = 0, const void *  data = NULL, SbNodeIdType  nodeId = 0  )

static

Passing the data in is optional and may be done later on the allocated vbo. The ownership of the VBO is passed to the called.
