Yes, I think he wants to implement the algorithms described in Cook's 1984
paper on distributed raytracing. Also the rays in the cone will most probably
be weighted differently (more if nearer to the center etc.).
On this topic: trip, why do you use random angles? You'll be using a whol lot
of cos() calls, which can cost quite a lot of time. I think there are faster
ways to generate random directions.
