Yes, that's where I got stuck. If anyone knows a nice occlusion
algorithm that solves this problem in vector space (without converting
to raster) I could probably also use it to speed up the rest of
ldglite as well. I'm hoping for an inspiration on this problem someday
(perhaps something using an octree?) but I'm not expecting one
real soon...

| Don: (...) There is a quite useful algorithm in my big computer graphics book. It is from 1991 (or before) and I think the title simply is "Computer Graphics". The algorithm is called "space-partitioning tree" or something like that. Jacob (23 years ago, 10-Aug-01, to lugnet.cad.dev)
