Detailed Description

This is a utility class used to allow sharing of index buffers while allowing for unique start and count, and mode parameters for rendering.

Constructor & Destructor Documentation

makVrv::DtSharedDrawElementsUInt::DtSharedDrawElementsUInt	(	GLenum	mode,
		osg::DrawElementsUInt *	indices
	)

Member Function Documentation

void makVrv::DtSharedDrawElementsUInt::setIndexBounds	(	unsigned int	start,
		unsigned int	count
	)

Set the index bounds.

This allows for independent start and sizes of elements while still sharing the same buffer.

void makVrv::DtSharedDrawElementsUInt::getIndexBounds	(	unsigned int &	start,
		unsigned int &	count
