Bad Egg  
After some trials and tribulations (including upgrading to LW10), I finally got a new version of Bad Egg finished. This one (unlike Game) I think is a clear improvement over the old one -- I actually tried to do something even more ambitious, that is, replace the yellow egg with a yellow-ish crystal egg, but the result wasn't really that good. Anyway, old one on the left, new one on the right:


[Click through for larger versions.]

The difference in speed here is obvious and astonishing -- half an hour versus forty-two, and that tells only part of the story because I also turned the quality way up, rendered at 16 times the resolution, and threw in depth of field to boot which is probably would have added another 20 times to the render time to the old version, minimum. Part of this is the 100+ times speedup in CPU, part of it is far better algorithms (add another 20 times speedup, maybe), but... My guess is that (if it didn't run out of memory and explode) the old machine would have taken north of a month to render what the new machine rendered in half an hour.

Stats for the original (render time 42:01:13 at 1280x960):

6 objects
77020 points
74322 polygons
0 lights
7 surfaces
0 image maps

Stats for the new version (render time 0:30:04 at 5120x3840):

48 objects
263589 points
266951 polygons
7 surfaces
0 lights
0 image maps

Yes, zero lights -- both images were done entirely with radiosity using a luminous surface instead as an indirect light source. Also, I guess the old version of LW only counted distinct objects -- both scenese have the same number of those (although the new one definitely has more instances of the objects).

I can see you being happier with the new version, but think that both of them have things to recomend them. Different personalites.

Actually, I'm kind of glad you say it that way; while I'm kind of repeating myself doing this little project of "updating" some of my older pictures (not least of all because they old versions are essentially lost to time and incompatibilities), I'm also don't want them to be too much of a repeat, I wanted there to be something new about them.
