[Radiance-general] rpict: "zero ray direction in localhit"?

[Gregory J. Ward]

Hi Lars,

This is one of those errors that's never supposed to happen, no  
matter what input you give to Radiance or how you set the parameters,  
and indicates either a bug in the code or corruption on its input  
(e.g., a messed up octree).  I don't know what is causing the problem  
in your case, but you could try sending me your scene (to me not to  
the group) and I can have a look.
