Hmmm... What kind of luck does one have importing .pov scene files into 3DWin?
If that works, I could get the wireframes out of 3DWin. I have a mess of
declares and loops in my scene file, so I don't know how well 3DWin would
parse it?

3DWin will not import .pov files sorry. Basicaly you can't make solid
objects in POV-Ray and get a wire frame output. POV-Ray has no wireframe
pre-view mode.

Just so you are not totaly confused by my answer you need to understand
the way that 3DWin makes wire frames. 3DWin reads 3D file formats that
are represented as triangles. When you ask it to output to POV-Ray wire
frame mode it connects each vertice of the triangles as a sphere/cylinder
combination and leaves the triangle out. You end up with a wire frame
representation this way. Very complex models with many triangles make
extremely large .pov files. You can also choose blobs instead of
spheres/cyls but those files are even larger.

I know this isn't wire frame, but I was thinking some variation and
improvement upon this... and as usual, I don't get what I would expect.
#declare SphereTexture1 = texture
pigment
gradient
camera_location
color_map {
[ 0.0 rgb
0 ]
[ 0.2 rgb
0 ]
[ 0.2
rgbt 1 ]
[ 1.0
rgbt 1 ]
}
} }

Many (Probably most) 3d modelling software create the surfaces of their
models entirely from triangles, which have points connected by lines
which can easily be displayed as wireframe. POV on the other hand uses
Constructive Solid Geometry which represents the model as a finite
mathematical shape. Not a surface, but an interior and an exterior.
These models dont have points connected by lines and therefore arent
easily displayed as wireframe. Although the triangle and mesh objects do
use points and lines. The only way I can think of to do it would be to
use another program to convert POV source into sets of points and lines.
POV's modeling approch is in my opinion much more elegant though it
doesn't lend itself to this type of representation. Kind of a trade off
I guess.

Polyray does a nice job of this.
Moray and Pov as well.

Hey ken did you not make a wire frame looking R2D2 w/ HF...? Some time
ago..........................................
in a galaxy far far away...................
there long lived a pover............................

I did but I don't think it is the kind of technique that Andy is looking
for and it has serious limitations.

As a connoisseur of these wire frame looking images
I would humbly request a repost.
