This is a wonderful animation, but a couple of things strike me right away.
    First, the deformation of the cube is great- it shows that "damage" can be
inflicted in the POV environment, which can be used to create very realistic
animations.  Second, when the cube dissolves into its components, they appear to
be "sticky", as they slow down too quickly on the floor.  It might be far more
impressive if they rolled freely and went along like little marbles.
    The lighting is great, the scene is eye catching, and overall I would give
you a 9 on this.

Cheers!

Wow, thanks :-)

Yes that would be good, I agree. However, as far as the simulation is
concerned, each 'marble' component is actually a fluid particle rather than
a sphere.. they just appear that way due to my blob settings. Indeed, the
whole 'component construction' came about through me messing with the blob
settings... it was originally intended to be a solid mass of 'stuff'.
However, I'm sure that by adept manipulation of the various parameters, the
'marbles' would slide much further.

And to you sir.

Neat.

How many particles are involved here? Does it take very long for pov to parse
this data?

This is cool. Someday, I'll write a particle-programm which can
do that... Until then... *sigh*

instead of everybody rolling there own particle systems, how about we club
together and cook up the ultimate be all and end all of pov particle systems
.... just a thought

1200 particles... parse time negligible really.. just a second or two.

And a damn good one at that!

Agree! I'd be willing to cooperate, but I'm not that good in math.. Let me
know if I can help anyway.. Even just the sharing of ideas between more
people would probably be good.. I wonder, maybe SDL is not the final
solution, but a step towards coding in C and expanding POV's native
abilities, starting with Pov4.. It could also be important for us to know
how much is going to change in Pov4; if there are already people considering
this. But anyway, it's not too early to start now.. Rune will soon be
releasing his particle system, and we know it's going to be good..

But is there an easy article on the net, that I should read to understand
more of this stuff?

Regards,
Hugo

Hmm... how do you start? Leap frog? I'm just curious how this can be done.
Best regards,

I don't get that with the "leap frog". Some unknown term to me.

How it could be done? Probably with some sort of
n-body-algorithm, with adaptive time-steps, good
approximation for hundreds of particles, springs...

A lot of stuff, so probably not be coded in pure
POV. *sigh*
