CG Form Factor computations on Cuda ? are there libs for this

Hi,

Would anyone know a library or code for computing form factors like between a point and a polygon or between two polygons or more complicated than that, including occlusion? I mean I’d like to do some radiosity computations, and
it would be good fun to be able to compute formfactors with such a heavy parallel computer as cuda.

I use the latest 2.3 which compiles fine on a not so big card (GF9500GT, on Pentium-D 3GHz, Fedora 10/64) but I 'd imagine some serious computations with small element, ray-tracing or culling should be possible.
