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.
