I don't necessarily need anything like that -- I just need to get my thinking out of the rut it's been in, so something specific to the geometry I posted earlier would be fine. > On the other hand, it might be feasible to > consider particular cases specifically, which > will also make it possible to apply to more complex > tasks.

I suppose I should start by trying for that, then converting to a set of triangles from there. Or maybe I should not convert... hmm... -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
