I told each bean that it loved the origin (linear force) but hated all
the other beans (1/distance inverse force). I gave them all random
starting positions and random velocity vectors and started iterating.
The result was a 1.3MB animated GIF, too big to post so I put it on
my web page (http://members.home.net/spock19) instead. This is the
last frame. Looks like the beans decided to tessellate a sphere...

Very aptly named. The continued rotations on their axes after settling down is
interesting, made me think of magnetic alignment still occuring.
Would bet this could get pretty neat if there were slightly different forces for
each, clumps and scatter perhaps?

How is that done? Where you base new values in a frame based on values in
the previous frame? I can think of a few ways to do it, but what is the most
efficient or most widely used? Nice anim, BTW.

There are just about as many ways of doing this as there are
people who try, but my choice is to generate all the points at
once using a standalone Java program and then writing them
to a big 3-dimensional array in a file. I load the file in POV
and use array indices (x=frame, y=location, z=orientation)
to control the placement of points. I can alter the object at
the point in POV, or do something radical like connecting the
points with cylinders, etc. all in POV. I also get to do things
with the camera angle and background, but normally I spend
all my time on the algorithm and end up with something lame
like "beans" to illustrate the results :-)

Cool ... I figure pre-processing is the way most people do it.

Quite a download but worth it.
I really admire the skill and knowdege it
takes to make an image like this (no
matter how simple, or complex it may actually be to
achive this.)
There is something about Particle Amimation which
unleashed the greatest force and power of both
computers and pov.
Now I will go watch my weekly StarGate. Not the
greatest TV program, IMHO, but what can one expect
at 2AM on a sunday night.

Are you in the pacific time zone ?

It's good enough that I record it faithfully. Some are better and some
are much worse.
