Thank you Paolo.

Here is another example, just emission media. I used an old CSG human model that
I made years ago (all of its parts are 'merged' for use as the  object-pattern).
I first made a CSG difference of it with a slightly smaller-scaled version, to
create a very thin 'shell'. When heavy warp{turbulence...} is applied, it looks
like wispy tendrils that are volumetric in 3-D. I had to use a very high
'samples' value for this.  The result looked like a nebula-- so I added a
spaceship! The background is a darkened photo of a real nebula.

I made an animation of this, with the camera moving through the media. I will
post it to my previous newsgroup thread in p.b.animations.
