With the talk of water bubbles, I thought I'd take a shot at making some.

wow, that's *awesome!* the texturing is great, excellent job! the line where
the floor and wall meet looks a little unnatural and the floor seems a little
dull compared with the rest of the scene, but this is a very cool scene
nontheless

<smile> Glad you like it. It's just a simple scene really.. Just slapped
together stuff.. The wall is a cylinder with a quilted normal. The floor is
also quilted, a plane. The water is just a box with marbled scattering
media. The bubbles are spheres and a large blob. It was more an experiment
than a finished product.

I really like the shape of the largest bubble, on top, but the smaller
bubbles right under it don't look right somehow, they sort of make it look
like a UFO or something.

You could be right.. I'm just working from intuition and guesswork. I
suppose I should have done a web search for some good still shots of air
bubbles first.

Nice positioning but it looks a little too symmetric, and shouldn't it be
somewhat transparent?

Actually, the bubbles are all "rgbt 1" with no normal or finish properties.
What gives them their look is the ior of the box with the scattering media,
and making the bubbles non-hollow so the media is not inside them. I figured
they'd be symetrical, simply from the relatively uniform pressures of the
water. Figuring that the only things to make them non-uniform would be
collisions with other objects and bubbles.

The shape is a little too regular, making it look more like a jellyfish. I
think air bubbles are more concave on the bottom with smaller bubbles
clinging to the bottom edge. Perhaps making them all blobs and putting some
negative blob components inside would help. I don't know, just thinking out
loud.

You're probably right...but when is water pressure uniform? Even in
swimming pools there are slight currents jostling bubbles into odd shapes.
Still, the general shape does look pretty good and lives up to DeWitt's
jellyfish theory.
I know the scene is meant just for test purposes but what really strikes me
is the media. It looks quite natural and works well. Do you think you
could e-mail me the source?
