I'm sure that it looks great, as your other items. However, I couldn't view
this animation.
What kind of codec did you use?

Looks very real until the second half of the animation. The space below the
water surface seems empty. Even with clean water, I imagine there is some
refraction (?) and a subtle colour change. If you used an isosurface, this
could be done with media (ohh, it's gonna be slow) but if you used a
heightfield, I don't know how.
The animation is compressed with Divx.

The water refracts in a different way than the empty glass box. Look at
how the refracted floor changes without and with water.

I don't understand why clear water would change the color of the light.

There's no difference between isosurfaces and heightfiels in this matter.
But why use media when you can use a fading interior?

Maybe not. But I'd expect some stronger visible changes inside the water.

I mean, a heightfield doesn't have an interior, so how could media work?

Guess I'd have to do more home-work reading the POV documentation!

Thanks Hugo
I don't trust the codecs from www.divx.com as the ones I've tried makes my
computers crash.
I'll ask around in the Mac forum to see if anyone has an alternative.

Yes, it has.

Hmm, that's a bit like asking an alternative to POV-Ray for rendering
POV-Ray files.

Well, it couldn't hurt to check if there was a Mega-DivX version around. ;-)
No matter - didn't exist any. Will take comfort in knowing that I'll save money
on the phonebill instead.
