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.
