I have converted wrl building data and would like to map the four sides and the
top image maps of the building to the mesh. The shape of the buildings is manly
cubical. How do I prevent the image to show up on the opposite site? I read
about Chris Colefax's and Ron Parker's "Coin" Solution, but I need a little help
to understand the "radial" pigment_map keyword and maybe someone can give me a
simplified example of how to use this method to map a image to ONE side of a
cube.

Thanks

I think that wrl data is mesh based. If that's the case, you can uv map 
your images onto it easily.

Yes, my buildings are meshes, but they are not just plain cubes (sorry if my
earlier description was a little misleading). They are full fletched buildings
with window frames and architectual 3d detail. I don't think uv-mapping will
work for me in that case. Don't you think?

You may need to have an inside mesh and an outside mesh if your meshes 
have no thickness. If they do you could try using UVMapper

Have you tried Poseray? It can read wrl data and export to POV-Ray. Are the 
images already attached to the wrl models? then chances are that they will 
be placed right already in Poseray. Just my 2 cts as I am not familiar with 
wrl.

Poseray is exactly what I needed! THANKS!! You Guy's are awesome! I also have
3ds data of the stuff I need to use. Came through beautifully! With textures and
everything! I'm just blown away! Thanks again!

UV maping will work for any mesh, whatever it's exact shape. If the 
facade have columns, it can map around them.
