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

[Gregory J. Ward]

Hi Despina,

If your geometry actually contains these creases, which it does, how 
can you expect Radiance NOT to render them?  The .OBJ file you sent me 
has numerous problems.  The creases are caused by incorrect surface 
normals at the patch boundaries.  If you take these out by running 
obj2rad -f, then you see the polygonal faces and get a lot of warnings 
about non-planar polygons.  I didn't check to determine if your 
polygons really are non-planar or if it's simply an issue with too few 
significant digits in your vertex coordinates.

I would recommend a different modeling system.
