virtual void makVrv::DtIndirectIndicesHelper::copyIndices	(	std::vector< int > &	indices,
		const osg::Geometry &	srcGeometry
	)		const

virtual

copy the indices from geometry into the aggregated geometry

virtual int makVrv::DtIndirectIndicesHelper::calculateNumIndices ( const osg::Geometry & srcGeometry ) const

virtual

number of indices across all primitive sets

virtual void makVrv::DtIndirectIndicesHelper::setModelName ( const std::string & modelname )

virtual

used for error messages

virtual bool makVrv::DtIndirectIndicesHelper::isModeSupported ( int mode ) const

virtual

helper function for checking if a mode is supported by this helper/indirect

virtual std::string makVrv::DtIndirectIndicesHelper::toModeString ( int mode ) const

virtual

helper function for converting from a GLenum to a string that contains the GLenum. for example GL_POINTS returns "GL_POINTS" useful for debug printouts

virtual void makVrv::DtIndirectIndicesHelper::setCopyRange	(	int	primitiveSetIndex,
		int	startIndex,
		int	endIndex,
		int	startVertex
	)

virtual

Specifiec the target primitive set and range to use for subsequent copy operations. This allows for a subset of the index data to be used rather than the full buffer. To reset to copying of the full buffer -1 can be used.

virtual bool makVrv::DtIndirectIndicesHelper::checkSrcIndicesOk ( const osg::Geometry & srcGeometry ) const

protectedvirtual

check if the src indices check out

virtual bool makVrv::DtIndirectIndicesHelper::checkAndCopyIndicesIfTriangleElements	(	std::vector< int > &	indices,
		const osg::PrimitiveSet *	primitiveSet
	)		const

protectedvirtual

Helper function for copying indices from a triangle element.

virtual bool makVrv::DtIndirectIndicesHelper::checkAndCopyIndicesIfDrawArrays	(	std::vector< int > &	indices,
		const osg::PrimitiveSet *	primitiveSet
	)		const

protectedvirtual

Helper function for copying indices from a draw arrays.

virtual void makVrv::DtIndirectIndicesHelper::printDetailsPrimitiveSets ( const osg::Geometry & geometry ) const

protectedvirtual

helper function for printing out the details of a primitive set

virtual int makVrv::DtIndirectIndicesHelper::calculateNumIndices ( const osg::PrimitiveSet * primitiveSet ) const

protectedvirtual

helper function, calculates the number of indices based on primitive type and vert count
