Ah, but then it would not be the final output image itself that has the
effect, only an object inside it. You would still have to do more than one
render to get the desired result. Then the question remains - which
advantages would a PP effect have over the method I used?

Would you add different preprogrammed types of dithering, or would you let
the user have complete control over how the dithering should be calculated?
The method I use gives me complete control.

My method is rather fast if it weren't for the AA. It looks *very* bad
without AA. As far as I know PP and AA doesn't work nicely together...

I grant you that.

Also works with my method.

I'm just trying to say that preprogrammed PP effects aren't the answer to
everything. It will never be as flexible as custom generated effects.

Currently, the PP patch writer has access to some input (image, depth-map,
normal-map, and maybe others), and he can then generate the output based on
these exactly as he wants. What I really would like to see is a patch that
enables the *user* to do just that. Sort of an "ultimate PP patch". If that
were made, many of the current PP effects could be made using #macros and
such instead. The user would have *much* greater control, and the whole idea
of PP in POV-Ray would work much better. I don't know if this is possible,
but if it is, then I certainly hope it will be made. Sure, it would be a
little slower, but that's a price I would gladly pay in order to get greater
control as a user.
