Member Function Documentation

virtual void osg::DrawElements::addElement ( unsigned  int) [pure virtual]
virtual void osg::DrawElements::dirty ( ) [inline, virtual]

Dirty the primitive, which increments the modified count, to force buffer objects to update.

Reimplemented from osg::PrimitiveSet.

References _ebo, osg::PrimitiveSet::_modifiedCount, and osg::ref_ptr< T >::valid().

virtual const DrawElements* osg::DrawElements::getDrawElements ( ) const [inline, virtual]

Reimplemented from osg::PrimitiveSet.

virtual DrawElements* osg::DrawElements::getDrawElements ( ) [inline, virtual]

Reimplemented from osg::PrimitiveSet.

virtual unsigned int osg::DrawElements::getElement ( unsigned  int) [pure virtual]
const osg::ElementBufferObject* osg::DrawElements::getElementBufferObject ( ) const [inline]

Get the const ElementBufferObject.

If no EBO is assigned returns NULL

References _ebo, and osg::ref_ptr< T >::get().

osg::ElementBufferObject* osg::DrawElements::getElementBufferObject ( ) [inline]

Get the ElementBufferObject.

If no EBO is assigned returns NULL

References _ebo, and osg::ref_ptr< T >::get().

const GLvoid* osg::DrawElements::getElementBufferObjectOffset ( ) const [inline]

Get the offset into the ElementBufferOffset, if used.

References _eboOffset.

virtual void osg::DrawElements::releaseGLObjects ( State state = 0) const [inline, virtual]

If State is non-zero, this function releases OpenGL objects for the specified graphics context.

Otherwise, releases OpenGL objects for all graphics contexts.

Reimplemented from osg::PrimitiveSet.

References _ebo, and osg::ref_ptr< T >::valid().

virtual void osg::DrawElements::reserveElements ( unsigned int  numIndices) [pure virtual]
virtual void osg::DrawElements::resizeGLObjectBuffers ( unsigned int  maxSize) [inline, virtual]

Resize any per context GLObject buffers to specified size.

Reimplemented from osg::PrimitiveSet.

References _ebo, and osg::ref_ptr< T >::valid().

virtual void osg::DrawElements::setElement ( unsigned  int,
unsigned  int 
) [pure virtual]
void osg::DrawElements::setElementBufferObject ( osg::ElementBufferObject ebo) [inline]
void osg::DrawElements::setElementBufferObjectOffset ( const GLvoid *  offset) const [inline]

Set the offset into the ElementBufferObject, if used.

References _eboOffset.
