I generate large drawables using indices (UIntArray) that point to the actual vertices (Vec3Array). When an IntersectVisitor visits this drawable, it takes at least four times the amount of processing time as that used for the same drawable created without indices. What is the huge difference? It seems that the one level of indirection for indices should only have a minor impact. I would appreciate any feedback to help me understand how to get the memory savings gained by using indices yet maintain the efficiency of the IntersectVisitor. Thanks.
