Dear RADIANCE users
I have recently been experimenting with the new MESH primitive =
introduced in RADIANCE 3.5. Furthermore, after the latest =
diff_HEAD_rad3R5.patch patch file has modified R3.5, the OBJ2MESH =
utility appears to compile a RTM (RADIANCE triangle mesh) without any =
bugs apparent.
The smooth phong shading possible with the MESH primitive renders =
correctly, but I am unclear how to apply a bitmap as a texture map using =
the compiled UV mapping co-ordinates.
The OBJ2MESH help file explains how the utility reads a Wavefront .OBJ =
file, but it does not suggest that the utility reads and compiles the =
corresponding Wavefront material file .MTL. The help file implies that =
the .MTL file should contain a RADIANCE material description.
My question is how is it possible to interpret the Wavefront .MTL file =
(i.e., in Wavefront format) into a RADIANCE material definition, =
specifically regarding referencing the bitmap(s) that will be applied to =
the RADIANCE triangle mesh file?
