Simple CSG roses with some rand thrown in for variety. They don't stand up
to close scrutiny, but good enough for government work...

BTW jpeg compression has been suprisingly unpleasant to them - is png
acceptable for the majority now?

I think PNG would be fine for everyone. It's the recommended replacement for
GIFs by the W3C and has built-in gamma correction. That's a great feature to
have considering the wildly varying gammas used in this group. :)

They are for me.  :)

Very nice.  Am I mistaken or you have been lured to the Dark Side (and
are now using radiosity)?

Not with this version - but there should be a radiosity version waiting for
me when I get back to work on Monday.

PNG's are not okay with me. Please don't use them.

Jpeg rules!

  Could you be more specific what is the problem with PNGs so that we could
perhaps find a solution for you?
  Being able to easily view PNGs is nowadays handy since PNGs are gaining
popularity.

  It depends.
  With the correct compression settings (which for some odd reason are seldom
available in any image processing program; they only offer a quality setting
and that's it, although there are quite a lot more settings to fine-tune with
jpegs) even that image could look a lot better without the file being much
larger.
  Jpegs are not good for every image, though. Sometimes you just get annoying
artifacts and there's little you can do about it.

PNGs are for most scenes a lot larger than JPGs. So for those of us who
use modems and don't have a flat rate, they are a waste of resources and
money.

Yes, that's handy. PNG is a very nice file format, but the lack of a
lossy compression mode is really a disadvantage compared to JPG.

I have to spawn an external program to view PNGs as opposed to automatic
inline viewing support in Netscape (this is a minor irritation). Secondly
the program I currently have associated with PNGs under windows crashes
whenever someone posts a progressive PNG (which means I can't view it
period when this happens).

Ah - this would seem to explain the problem. PSP has no options with regard
to super-sampling. I'll get hold of cjpeg and see if it fixes those
occasional images that don't respond well to standard jpeg conversion.

I'm a great respecter of file-size in posts which, all in all, is about the
only justification for jpegs. To be frank, given the POV is a fairly
technical, graphics orientated program, it seems hard to have much sympathy
for those who haven't got around to solving any technical problems to
viewing png's in this group.
