We recently got a (Demo model) Personal Iris 4D that has a 32 bit frame
buffer and a Z-buffer.  I would like to create a 3-D surface mesh that
has a different color at each vertex and is shaded by some lighting model
I've defined using lmdef.

I've been able to get my colored surface using the bgntmesh, v, cpack and
endtmesh commands but it is not shaded by my defined lighting model.  If
I bind a material when rendering the surface it renders as that material
(Not multi-colored) but it is shaded by my bound lighting model.

So is it the case that interpolation of color and shading are mutually
exclusive?

Thanks
