Thanx!
(POV is using backward raytracing, right?)
But, how come you have to shoot rays from the lightsource to know the
shadows? Can't you just continue until you reach a light, and if so, you
know if the points before are lighted or not??
BTW, what does "L: a*x + b*y + c*z + offset = 0" mean?? i don't
understand the offset thing 8(
