I'm beginning to think that there shouldn't be much blur at all in the scene
as I've set it up. I believe that it should look like the trailing side of
the spheres are blurred slightly, or indefinite. Additionally, there should
be some elastic effects upon the central spheres (which I have ignored for
now). At any rate, I am getting a blurry sphere with leading/trailing blurs.
Not what I wanted?

I'd love to see the code for the texture...

This is, essentially, T_Gold5E (I think it is) with just minor megapatch
changes. Unless, I made a math error somewhere. ;) I haven't checked it,
'cause it looked good enough.

David, Steve, wrench = work in progress. Thanks for the input, but I
probably won't be using an isosurface in the final render, either. ;)

Looks good - but why so long to render? The brief experiments I done with
radiosity do not suggest such long render times - or was it the use of
radiosity for each of the samples required of the motion blur?

I like the image: it does suggest motion. How to make it more realistic:
I can't help you there.
The collisions are near elastic though, if I'm not mistaken. With
inelastic collisions much energy is dissipated (into heat mostly) and the
movement decreases rapidly! The fun of these things is that they continue
for a long time...

I've been using the same global statement from scene to scene. That way all
I have to do is change one value ('distance_maximum') and vary 'count' for
fast or slow renders (testing). 'Inelastic' used a thousand count. Blur
didn't help much for speed with sixty-four samples taken.

"Should" be elastic. If I continue to have the same problem, you will see
what I mean. I couldn't make out, from still shots, which direction the
elements were moving in. Probably my own stupidity (free shot). We'll see.

Oops, forgot megapov quit using distance_maximum. So, changing it doesn't do
much :D
