| | | | | | | | At each level of recursion, we have to go down the right branch if it exists. But if we do this before we test the current node and the left branch, we can eliminate those tests in the likely case that we find a closer object in the geometrically larger right subtree. This gives about a 2X speed improvement according to `make bench'.
* Fix some memory leaks.Tavian Barnes2009-10-191-10/+16
| | | | | dmnsn_delete_pigment() was not using the free_fn, and kD splay trees were not being deleted after raytracing finished.
