Sorry for the simple scene decoration, but I'm too impatient to model
anything great while I'm still experimenting with the particle system
itself.

Anyway, I've made some improvements. The bouncing is better now and I've
improved the emitting method so that it is independent on the calculation
steps.

And then I tried to make the emitting point into a line.

Like my other recently posted animations, this one is cyclic.

Hope you like it!

Yeah, i would really like to see that flowing over a nice isosurface
cliff...

BTW, would it be possible to add some more smaller particles to the
waterfall, that would look more realistic IMO.

That's great..the bounce is better. Can any object be used to obstruct the
particles, not just spheres?

I'm interested in what you are trying to accomplish...so far, the 
particle_system patch can do all of this, and probably faster. Do you 
just want a particle system that can be used in ordinary MegaPOV? Or do 
you have a specific goal in mind that the particle_system patch isn't 
suited for?

I've never used the particle_system patch so I don't know much about it's
features. For example I didn't know that the particles could be glows and
that it supported cyclic animation.

Since I haven't tried the particle_system patch I don't know if my system
would have any advantages over it. Anyway, my patch will be *mine*, it will
be made my *me*, it will work exactly as *I* want! :)

I didn't know that; it sounds interesting. I think the general awareness of
your particle_system patch and its possibilities could be improved if you
posted some animations showing it's various uses. Or maybe such animations
are already available somewhere?

Thanks!

Yes, any object can be used. The object cannot be animated though, as it
will likely cause particles to "fall through" the surface.

It doesn't support flowing (not currently at least), it only supports
bouncing.

Yes, that would be possible.

It does not need to flow, even if it's not a very steep cliff, bouncing
would perfectly suffice.  As i understand it you could simulate some kind
of flowing by making the particle lifetime high enough and using a high
energy loss when bouncing.

The particle_system object itself will render as a blob, but you can 
easily just use it as a controller for your own particles, and make them 
whatever you want. And it doesn't do cyclic animation...that's one 
advantage of your include. I'm not sure how I could enable cyclic 
animation...

That's a good reason... :-)

I posted some images and animations on these groups a while ago, and 
somebody used it in an image of some odd robots spraying stuff at a 
mutated rug/chicken thing.

I thought so too at first, but it doesn't appear to work that way. The
particles come very quickly to a complete stop. :(
