[Radiance-general] lighting per pixel or per face? - obj2mesh(new)

[Despina Michael]

ok, thanks for the information! I think I'll try a more professional 
modelling tool.

I was thinking that maybe there was a way to interpolate normals and find 
each normal per pixel.. so I supposed that lighting would be smoother.

Thanks again,
Despina
