Thanks.

See p.bscene-files : "ToVolume: Object-To-Volume Conversion and 
Rendering Process".

Note. With that include he provided an all POV-Ray canned process for 
converting any object into a 3D isosurface using generated, stacked 
blurred-image planes. I've been working mostly outside his include, 
though using his blurred image technique via GIMP with just one plane, 
one image, as the basis for various isosurfaces.

The blurred image technique at the core of his ToVolume include is a 
remarkably flexible and easy way to "create" isosurfaces. It is 
basically 2D image -> blur(1) -> save-image and render.

While I'd used images to deform isosurfaces, I did not get that 2D 
images alone could define isosurfaces until I saw Sam was doing exactly 
this (and more) in his ToVolume include.

(1) - The blur rounds, sets the 1-0 gradient and effectively sets the 
max depth of any further isosurface surface deformation.
