Al Hastbacka asked:

>>Besides mediical applications, are there some other good uses of color in
the RP business?

Al, in years past I was involved in a project dealing with a power-plant design.
Through the course of this project, I became familiar with specialized CAD tools
for plant design. In some phases of the design, there was such a tangled mess of
pipes, that a color coded model would have been great. The current state of the
art is to employ model builders to create a life-like model of the plant from
foam and balsa wood. This would apply to all petro-chemical plants as well.

But coming back to the old STL format, how are we going to shoe-horn color
information into it? As for textures, perhaps Mr. Brock Rooney might wish to
enlighten us on how many triangles would be needed to represent realistic
surfaces, such as grass and hair?
