I started to work on a couple of macros for mesh-primitive-output.
They got almost the same syntax as normal POV-primitives, but the
output - meshes. Together with the inbuild PCM-Output-support it is
now finally possible to use all those nice macros from Chris Colefax
and Doug Eichenberg on primitives. The only drawback is that you can't
use them in CSG (well, aside from union of course). But I think it's
still nice and comes in handy for my next project. Here's an early
image using Chris Colefax' hair macro, it took 6 hours on my Athlon
600/256 MB (time to upgrade that thing). I would have used Doug's
macros but they took even longer... Radiosity setting is as poor as
possible (Radiosity_Debug from rad_def.inc), but I hate to wait :)
Sorry for the big file size, but JPEG wasn't really nice to the hairs.
Comment & Critic welcome as always

Thanks, but I think most of the credits go to Chris Colefax for doing
those wonderful hair!

Cool stuff, the hair seems to have strange artifacts when the angle is
sharp (see attachment) though.

Thanks! I noted the artifacts, too. Don't know if they are due to
anti-aliasing (parts of the hair dissapearing) or a problem in the
algorithm. As this will hopefully end up in an animation, I don't care
about it too much - I hope it won't be noticeable after all :)
