UV mapping in Radiance

1

Folks - I have been reading up on the basics of using UV mapping in 3D modeling apps, in general to apply textures, etc. to complex 3D surfaces with greater control.

Does anyone use UV mapping here with Radiance? Is there some workflow that has been developed to take a model from an external modeling app (I use Lightwave) and export a model (with a UV map and an applied image map) into a format that supports such mapping (say .OBJ) and then bring the model and its UV map and corresponding image map into Radiance?

Maybe this technique is fairly straightforward or maybe it involves more thought with respect to writing .cal files and such.

Thanks,

kirk

Export as and obj and take a look at this post

I've never been successful, as my 3D app doesn't export the map with the
.obj, but it should work if you can export a good .obj

Hi Kirk,

The mesh primitive is the best and easiest way to get UV texture coordinates into Radiance. See "Fitting texture to mesh" thread from Oct. 2003:

Nice! Thanks Rob, I'll give that a shot.
