I have a model created in software other than PovRay. I can export it to Pov
and render a scene with it. I would like to know if there is an easy way to
render that model(object) as a wireframe object, when I render the scene.
Thanks,
Les

Not as an option withing POV-Ray itself. I do seem to recall that 3DWin
has a wireframe output option but at the expense of creating tens of
thousands of cylinders to connect the vertice points. It creates HUGE files.

I recall doing that once with Warp's mesh compression tool and some of
his associated macros. Try his Page.

It's not possible to create a wireframe with POV-Ray like a renderer does,
because the thickness of the lines will be less (or the lines disappear)
when the object is far away from the camera. A renderer always makes 1 pixel
lines.

Thanks to everyone for the information. I'll check out Warp's page as
suggested.
Thanks again,
Les

Ahem...POV-Ray *is* a "renderer". A renderer is just a piece of software
that creates an image.
The previews you see in modellers are usually scanline renderers which
take a large number of triangles as input and draw them one by one on
the image. Since it already has the triangle data, it can easily just
draw lines for the triangle sides instead of drawing the whole triangle.
POV is a raytracer, and computes the image pixel by pixel, sending rays
into the scene and intersecting them with surfaces, which usually are
intersected directly instead of being reduced to triangles. There is no
way to know that a line pixel should be drawn, and an object just big
enough to cover a pixel at a certain distance is likely to get missed
and will either get fat or disappear as the distance changes, so
simulating a wireframe with textures of a bunch of cylinders still has
problems. It also won't be any faster than ordinary rendering, and the
only reason modellers use it is for speed.
