Regarding Anthony D Baye's request for volumetric textures, I've thrown together
3 examples. The code is in p.b.sf. Am I on the right track with any of these
examples Anthony?

This one only uses media.

Bubbles were also mentioned. This one uses only 2 objects.

The first and last are what I had in mind for effect, but I was wanting to
achieve it solely through the use of a texture, not a composite object.

The second image is not really what I was talking about, but it's a very cool
use of media.  What's with the hard shadow on the lower left?

I might concede the point here, I suppose.  I had forgotten that Material
encapsulated Interior.

Regards,
A.D.B.

A texture is by definition the surface of an object though. Material would be
more appropriate.

It's the unlit part of the scattering media. I've also had this problem when
making planets with media clouds and atmosphere.
