[Radiance-general] obj parser in obj2rad and obj2mesh

[Greg Ward]

Hi Lars,

Both images look like they are suffering from image sampling errors.   
You should try rendering these at higher resolution, setting -ps 1 in  
rpict (or "set ps 1" in rvu).

I assume you're using the latest version of Radiance (3.6)?

P.S.  If the problem persists and isn't just image sampling, please  
send me your .OBJ file (compressed), and I'll have a look.  Don't  
copy it to the mailing list, though.
