I just had a small brainstorm about the pigments and normals in pov.
How hard would it be to make the code to do this:
add{
pigment{wood}
pigment{gradient y}
}
It would be like the paint-types in Photoshop. You would get to choose
from multiply, add, subtract, difference, etc. It seems perfectly
feasable to me. Is it?
