Member Function Documentation

◆ copyMatchInfo()

SoElement * SoGLVBOElement::copyMatchInfo ( ) const
virtual

Implements SoElement.

References SoElement::SoState.

◆ 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

References MAX_VBO_TYPES.

◆ matches()

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

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

Implements SoElement.

References SoElement::SoElement().

◆ pop()

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

Reimplemented from SoElement.

References SoElement::SoElement(), and SoElement::SoState.

◆ push()

virtual void SoGLVBOElement::push ( SoState * state)
virtual

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

Reimplemented from SoElement.

References SoElement::SoState.

◆ unsetVBO()

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

References SoElement::SoState.

◆ unsetVBOIfEnabled()

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

VBOType type,
SoVBO ** vbo,
int numBytes = 0,
const void * data = NULL,
