privatedelete

not allowed

virtual bool makVrv::DtIndirectAggregateIndicesHelper::checkSrcAndDstIndicesOk ( const osg::Geometry & geometry )

virtual

check if the dst (of aggregated geometry held here) indices check out

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

virtual

copy the indices from geometry into the aggregated geometry

virtual void makVrv::DtIndirectAggregateIndicesHelper::cancel ( )

virtual

called when the DtAggregatedGeometry is being destroyed so we can early out of the copy process

virtual bool makVrv::DtIndirectAggregateIndicesHelper::isModeSupported ( GLenum mode )

virtual

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

Referenced by copyIndicesOnMatch().

virtual std::string makVrv::DtIndirectAggregateIndicesHelper::toModeString ( GLenum mode )

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

Referenced by copyIndicesOnMatch().

static int makVrv::DtIndirectAggregateIndicesHelper::calculateNumIndices ( const osg::PrimitiveSet * primitiveSet )

static

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

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

protectedvirtual

Helper function for copying indices from a triangle element.

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

protectedvirtual

Helper function for copying indices from a draw arrays.

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

protectedvirtual

helper function for printing out the details of a primitive set

template<class T >

bool makVrv::DtIndirectAggregateIndicesHelper::copyIndicesOnMatch	(	std::vector< int > &	indices,
		const osg::PrimitiveSet *	primitiveSet
	)

protected

templated function used to copy indices that are a DrawElements vector.

this avoids three instances of the same exact function with only different function argument types
