  No easy parallel rending with actual mechsim's :-)

I must really say that I like those mechsim's. Also the way it was
implemented by Christoph
is very logical (so far i can understand as a non mathematician).

I see no other or better way to implement it directly in POV-Ray.

The other thing is a diffrent thing:
A separate program. These are clearly two diffrent ideas with diffrent
potential.

However we should not compare apples with oranges. A bultin system has other
advantages (shorter
description-code etc.) and other disadvantages (see below) then an complete
external system.

I've tested all ways supported by POV 3.5/MegaPOV 1.0  (without patching)
and I did not find any way
to render mech sims on "multiple CPU's" at the same time.

So, while writing this posting, I 've distributed  "bar.pov"  to another PC
(using SMPOV)  so I can work here while the 700 frames get rendered on one
CPU. :-)

If we had an Animation-"pre-compiler" (Willem's idea) which would (sounds
phantastic?) output in the same way 700 "static" POV-Scenes, for the
"Mech-Sim" - THEN I could render a lot of them "parallel" on many CPU's or
even render then "in tiles" (each does not work with the current system).

For people with only 1 CPU no Argument, but for those who 'd like to speed
things up, this is a point.

The builtin mechsim-system is fine and is perfect as it is. To make mech
sims that can be rendered parallel, it may be necessary to make other steps
on a higher level and distribute static scenens to the renderer, like Willem
said.

At least so far from what I found out till now. If someone has an idea how
to render these mechsims parallel,
I'd like to hear it.
