Well, my own connection is rather poor, so I rarely download the largest
animations in this group. Sometimes I see animations posted with
unnecessarily high quality settings, and I don't want to do that myself. But
maybe just a bit bigger... :)

I agree that it's a bit small but great in other ways. Plays only on my 
Xing player, not on the MP. Same question: what anim codec did you use 
here? When will there be a nice and useful MP for w2k??

This is wonderful work Rune.

Q: How much more difficult would it be to make the particles interact with
the ground plane? Maybe just keep bouncing until they expend all their
energy. My suggestion would be to not worry about making the particles
interact with one another, as I don't think it would be especially
noticeable to the eye at this speed.

I am *really* looking forward to the release of this code.

That looks really nice, i wonder how much physics there are involved, what
parameters you can influence.

I used mpeg1 I think, but not with the standard bitrate or resolution.

That I don't know...

Somewhere between "piece of cake" and "headache". :)

Don't know. If I implement it, which settings would you like to be able to
control?

I certainly won't make the particles interact with each other!

I'm glad to hear that! :)

Not many physics. Practically only gravity (which can also simulate wind).

There'll be more though if I implement collision detection.

Which parameters would you like to be able to control?

It would be good to influence viscosity and surface tension of the liquid
which is the main factor for the size of the particles and of course for
their behaviour when colliding.  

I still have not tried Chris Huff's particle system patch, but i think it
offers some things of that kind.

I can't speak for anyone else, but, as far as I'm concerned, you could post
three or four of those every day. :-) I like them a lot!

Sorry, but that's way beyond the scopes of what I'm doing.
I'll maybe do some very crude collision detection with objects, but no
interaction at all between the individual particles.

Well, there's a big difference between an include file and a patch. And I
don't intent to duplicate his work anyway.

Features such as surface tension are pretty much only relevant when
simulating water. But I don't intent to specialise my particle system in a
specific direction. I intent to make it simple and general and to make it
able to simulate many different things.
