So, I've done extensive tests and lots of trial runs. Every time I spotted a
mistake, I needed to correct it, check the implementation and redo all
trials to see if everything is still working as expected. I've finally
tracked done one of the major mistakes I made: the aging of a particle
wasn't calculated correctly, which lead to quiet unexpected and strange
results...
Anyways, now that it seems like really all issues with the simulation are
taken care of, I post yet another animation, showing the infamous
funnel-scene, though it was enhanced and modified for a more extensive
testing ground with curved surfaces which "trap" particles.
You can't really see how the particles fall through the second funnel,
because the other particles obscure the view, there's way to much action and
thus it gets quiet irritating when trying to follow a certain particle
through there. I've changed that for the final release, but as I want to go
to bed now, I want to send this post on its way. The revisioned version will
be uploaded to my homepage later tomorrow or the day after (along with some
other trial animations).
Now, all I need to do, is finish a few loose ends, write a proper HTML-Doc
for the System, and then its good to go. :-)
Until then, enjoy this animation. Feedback appreciated!
@Rune: I know, not a typical User-Scene to have some balls bounce around in
some funnels, but "proper" scenes are due next week, I promise. ;-)
Regards,
Tim

Hm, well, not many replies to this one. Guess I've posted too much particle
stuff lately, eh? :-)
Anyways, for those interested, I uploaded three animations to my website
showing several revisioned scenes: this funnel, with the second funnel
replaced by a slide, the scene with the particles using vturbulence as wind
and the Rain-Scene. These three were testing scenes and were quiet useful to
test various issues, but for the Release of the System I plan on making some
more typical scenes, e.g. fire, smoke, rain...
Regards,
Tim

wind demo - gravity seems reduced - hangs too much
rain demo - even on a plastic surface, rain drops merge, maybe if both
raindrops in contact and both in contact with surface could get merged ????

There's no gravity at all in that scene, the particles are more or less only
moved by the turbulenced field. More like dust-particles in a water-basin.

????
Problem with that was rendering times. Using blob to "connect"/merge the
different particles to each other would increase rendering times
drastically, and merging particles to the surface of objects would be quiet
complicated to achieve more realism than just sinking the spheres half-way
into the surface...
That aside, I also wanted to show that particles can have a radius and will
properly interact with the environment.
Regards,
Tim
