Since the thread seems to have largely run its course, I should like to conclude
by reiterating thanks all contributors and repeating some very useful references
that were posted in another thread by "dlm"

====== Begin quote from "dlm" ====================
.... short code competition, round 5 is posted at
http://local.wasp.uwa.edu.au/~pbourke/modelling_rendering/scc5/
This year it is a 100 frame animation with a 512 byte max.
Entrants will vote on the 'craft' of the animation.

A Chris Colefax animation primer is available at
http://www.geocities.com/SoHo/Gallery/2006/xani.htm

Reading past entries is quite instructive - TEK has been particularly
generous in sharing his techniques. e.g.
http://local.wasp.uwa.edu.au/~pbourke/modelling_rendering/scc3/final/swokwz_l.pov
http://local.wasp.uwa.edu.au/~pbourke/modelling_rendering/scc4/final/l_nfzrtu.pov
and on this NG.

Also "Tips for Short Code Contest" was posted by Mike Kost in p.g 12 Oct
2006

I don't remember being asked but I certainly have no objection.

Indeed, if you or anyone else would like to contribute to a list of tips then I
will create a document on the scc5 page. I've already had some contributions,
one used some neat scripts to automatically reduce the byte count.

Macro are useful too in order to apply translations or other modifiers to
different objects
e.g.

sphere{0 1 pigment{color rgb 0.2} translate<1,2,3>}
sphere {1 1 pigment{color rgb 0.4} translate<1,2,3>}
sphere {2 1 pigment{color rgb 0.6} translate<1,2,3>}

becomes

#macro M(c)pigment{color rgb c}translate<1,2,3>#end
sphere{0 1 M(.2)}
sphere{1 1 M(.4)}
sphere{2 1 M(.6)}

  That's at least 6 characters too long.

For anyone interested, I'll take the liberty of assuming that Warp meant that
"color " could be omitted.

yet better

#macro  M(l,r,c)sphere{l r pigment{color rgb c}translate<1,2,3>}#end

this saves you two spheres :-)

Now, you can have different translations for each instances.

You may want to put some of this on the wiki.

While we're at it - if you want high-ambient objects like suns or radiosity
emitters, don't use ambient 1 in a finish statement; use a high color value
instead.

e.g. pigment{rgb 1}finish{ambient 1} -> pigment{rgb 9}

This produces very similar results, easily tweakable to one's purposes...
