Hallo!
My problem is not quite related to pov, more to 3ds, but I'm a pov user
and I hope you can help my.

I have written some pov-macros which calculate the edge points of
triangle and writes these to an pov include file. Each triangle has a
different color. Now I want pov to write this triangle data into such a
format that it can easily imported by 3DS. What's the easiest way to do
that? I have a program that converts POB, RAW and some other formats to
3DS. But for POB I had to find a parser first. I don't know anything
about the RAW format. Is it possilbe to write the triangles with pov
directly into a 'raw' file?

Thanks for your adivces

-Micha

A 'RAW' file just lists triangle vertices.
A single triangle with vertices :
V1x,V1y,V1z
V2x,V2y,V2z
V3x,V3y,V3z
would look , in the RAW file, like:
V1x V1y V1z V2x V2y V2z V3x V3y V3z
(no commas, just  space separating the 9 coordinate
numbers)
Each triangle goes on a separate line.
I think you can add a triangle's normals too, just by putting them
on that same line.
I don't know anything about colors in RAW files, though.

You could use #fopen, #fwrite(), and #fclose directives
to get POV to write the RAW file. I've got examples
I've done lying about someplace and I could find them
if you want to see.

If you have a union of triangles (not a mesh, and no smoothing information)
in pov syntax you can use Crossroads to convert it to other formats. This
is one of the few official occurences of POV-to-other-formats conversion.
I'm not sure about the colors though.
