Member Function Documentation

void GU_OBBTree::createDebugTree	(	GU_Detail &	gdp,
		int	depth = `-1`,
		int	prim = `-1`
	)		const

Create a GU_Detail showing the OBBs at each level of the hierarchy.

If the depth parameter is non-negative, then only leaves at the given depth level are included. If the onlyLeaf parameter is non-negative, then only boxes containing that primitive are included.

GU_OBBTree& GU_OBBTree::operator= ( const GU_OBBTree & )
