As the Subject says, I'm very new at this, and not sure what I'm doing wrong.
The image I am trying to render is one of a sphere of nested multi colored
spheres with a wedge removed to reveal the inner layers. I get what I think I'm
suppose to get, except the inner spheres are speckled with lots of black pixels.
I read the piece about coincident surfaces causing this effect, but if that is
what the problem is, I don't know what surface needs moving.
Can anyone tell me what I've done wrong?
