Hello everyone! Here's a scene showing a little code I've been working
on in POV. It's based on some simple 2d particle simulations I've also
been developing in Euphoria.
In this render no gravity is taken into account and only a mild wind
from the right exists. Each sphere is moved away from any surfaces which
might be inside it, and uses only six points of reference for its
collision detection.
It makes a nice-looking model for sphere packing.
Questions, comments?

Beautiful... very photorealistic. Are you planning doing an animation of it?

Hi Fernando,
An animation of this would take very long if I have to use variables
that are destroyed at each frame. The process I used is iterative, and
the varibles need to build on themselves after each frame, not be
destroyed. I have no idea if POV-Ray handles what used to be called
'persistant variables' or not.

MegaPOV 0.7 supported them IMHO. But you can simulate them without
problems, using File I/O. That's the way most particle systems do it
(e.g. Rune's). If you do not want to reinvent the wheel, you can take a
look at Tim Nikias' I/O Macros which can be found at
http://www.nolights.de/download.html#IO-Macros
HTH,
Florian
P.S.: You hopefully know that the only reason I'm telling you this is
that I really want to see this great image animated ;)

IMP could help with the rendering.

The problem with IMP is that I'm pretty sure that in this sort of animation
one frame depends on the previous frame, because it's a physics simulation.
However, one could compute the position of the balls before the rendering
and then the rendering would be parallelizable.
Sniff! I would love to have some free time to do some experiments like this.
But it's Saturday 6pm, and I still have to do some work.
Fernando

Looks really realistic! How the spheres lay in realistic places really lends
to that as well.

Oh well, if you have time later then :P
