A simple dot product will do the trick. Let v be the vector that goes from p to c (the center of the sphere). Then if. d. v > 0 // the distance to the ray can be computed (Sphere 1) d. v <= 0 // the sphere is behind the ray ...

WebIn the first screenshot, you can see the light is illustrated by a small sphere, notice how the side it is on is not light?
