I would suggest a separate app that outputted pov among other formats -
share the wealth and all that :)

Hey, looking great!

I like the look of the heightfield this time around...it seems more real.

My one gripe is that in the beginning of the movie, in the upper stream,
when the little "bowl" fills up, it looks like the water has the consistancy
of gel (moving slowly).  Perhaps it's because of this being the slow motion
version?

Oh no! The word looses it's meaning when it's used too often!

AWSOME ROLEX is for 100% photorealistic renderings only. :)

But thank you anyway! ;)

My system can do collision detection with almost any POV-Ray object. How
could that be supported in an external app? Besides, I'm not able to program
separate apps either. I only know POV-Ray script.

Great!

I'm not sure, but it looks like the water has to flow a little bit upwards,
which could cause the slow moving. I could make the water more bouncy, and
to view the clip in real time instead of slow motion would probably also
help.

    Not really - you're already doing collision detection, of a sort, in
your POV script, right ? Well then, you just run the overall physics in your
external app, have it write out particle location and velocity information,
and keep the collision detection in the POV script.
    That's the way my particle system is going to work (seeing all this
discussion about particle systems got me to thinking about them and then I
just had to have a go at writing one - looking reasonable, so far, expect
anims in p.b.i. soon....), until I've got a full modeller written anyhow,
then I plan to be able to do it all from within that...

Have you tried it with a plane for example? If you get misses there, it
can't be a triangle problem...

BTW, you may have noticed there are no spilling anymore. I think that the
spilling particles were in fact partly caused by a bug - which I fixed...

However, it may be possible still to make it happen using certain settings.
But for now I like that I have better control over where the particles go...

According to the tests I've done, the errors always happen at "cracks".

There are small cracks both in height_fields an in CSG objects.
