Hi Joachim, isn't at all a stupid question, of course i have to care about this, but i still thought about this issue, may there a two possiblity, first i store the data still in a array and just refere to them from kd-nodes, or a link the kd-nodes, i we assume that only triangles are stored in the leaves, then may we link juste the leaves.
(a stupid idea: may we can "link them to a ring", then may we can order them in depth, may not. i have to think about this, but i we have a strategy to walk through depth sorted you will see a next application of kd-tree (heuristically depth sorted) ) /adegli 2007/10/11, Joachim E.
