Whoa..
I'm just wondering a bit here...
Is there an interest/objection in me porting some more of the larger #macros for
object to
an external program??? of course, credits will be given..

As for why I am wondering, is from my interest... since I run a p-166 it's pretty slow
in
parsing, and once I have made a final object with settings I like, I'd like to speed
it
up... This is as far as I know one of the better ways. (I know, #debug, #fwrite....) 
Any ideas/demands/objections will be welcome. As for now, I do what I want, and
brutally...(hard coded)

As for programming level, it'd probably be in win32 mode, since it is easier to write
once
I've made the algorithms... And it is easier to develop some more...

well, respond....

You have my permission for what it is worth.

You may port my torspline macro, but you probably shouldn't have to,
as there's a link to a program that does essentially the same thing
already on my page at http://www2.fwi.com/~parkerr/traces.html

I find that parsing really large text files takes MUCH longer than
running the while loops in POVRay (or the math).  TRUE, the external
code may GENERATE the files faster, but unless you move the macros into
POVRay internally (patch them in) I don't think you will increase speed
of parsing.  Perhaps some not too large group of objects may parse
faster than they can calculate and parse, but when files approach 500k
to a meg, then parse MUCH slower than the calculations take.  This is
only from my experience, but I've just finished my Connected Sphere
macro, and comparing it to the same input from a file (granted some
redundant input) it takes FAR less time even though it is calculating at
the time.

This is really very much depending on the scene.. 
Take the macros that made the gnarled tree..
on my pc, 3 trees at recursion level 5(I think) took around 1 min 40 sec to parse,
while
the same files, though rather big, only took 4 sec. 

I can make some exact stats if you'd like.

If you are very motivated, I would be very happy if you port my Particles Generator to
an
external program. Because the Anti_Collision is very very slow. I'm too busy to do it
myself
for the moment.
I think it's an excellent idea to make porting (portation ?). I am always looking for
programs

to speed up my tracing (very very slow machine).

Ah..
I'll take a look at your code...
My first questions are, does your macro take care of the other objects in the scene
(Useless in a prog. then) or is the collision detect only for the objects it create ??
well, the easy way is : TRY IT ! So I will..

Ho, I've updated...
