If you have the formula for the object, the normal at a given point <x,y,z>
is

(<func(x+small_val,y,z),func(x,y+small_val,z),func(x,y,z+small_val)> -
<func(x,y,z),func(x,y,z),func(x,y,z)>) / small_val

Taken from memory, I might have screwed that up. It's basically just the
gradient of the function.
