  I have as yet insuffecient data to perform a meaningful task.

  I am not arguing it's potential for the artist I am crying for more
imput on how to use it. I even to some degree understand the 3d image
file concept but don't know where to start in it's implementation.
For example the program tga2df3. If I wanted to create a simple shape
let's pick something simple like a narrow cylinder with a sphere on top.
Your basic tootsi pop shaped object. What kind of tga images would I
feed tga2df3 to realize this shape when applied in a density statement ?

  Give me fundamentals I will worry about concepts later. I need buttons
to push not fancy words to ponder. Give me a damn monkey wrench so I
can start to work with it.
