*Sigh!*
I had hoped nobody would ask...
The short answer is "just toy around with scene scale and distance until
you're happy".
The long answer is that there are /two/ minimum distance mechanisms,
/both/ of which may kick in independently:
- One mechanism uses a global constant, MIN_ISECT_DEPTH (defined as 1e-4
in POV-Ray 3.7), which is tested in global scene coordinate space.
- Another mechanism uses a constant depending on the type of primitive,
ranging from 1e-6 to 1e-2, which may be tested in global scene
coordinate space or some local coordinate space, also depending on the
type of primitive.
