Quoting Josh Steiner josh@vitriolix.com:
thanks. i've tinkered with the number of slices, but thats not really
what i'm taling about. if you look at the top center of my screenshot,
there are two balls which have each single white pixels towards their upper left... when this is animated you see these little white pixels flashes on lots of the balls and it makes it look pretty messy.
also, no matter how many slices you have, you still get the jagged pixels where the edges of the ball meet the black background unless you
have antialiasing like in the jitter screen.
chris clepper responded off list to suggest doing [alpha]->[polygon_smooth]->[geos] which produces these results:
http://eds.org/~joschi/r/spheres_trans.png
so this makes the spheres translucent, but he edges of them are still jagged and not antialiased.
What hardware are you using? The ATI 95/96/97/9800 do not support polygon anti-aliasing in hardwarer anymore. They do support FSAA, and I have added this capability to GEM, but it had only been tested on OSX. If you are able to compile GEM for Windows just change the define around the ARB_multisample code in GemMan.cpp.
To make the spheres not transparent then add a [color 1 1 1 1] to the chain. The fourth argument is for alpha and will modify the transparency of the objects in that chain.

ps - my mails don't always seem to make it to the list. you can forward this reply if it fails to reach the list.
btw, i'm using gem-cvs-2003-08-11.zip
thanks all!
