[Radiance-dev] Errors in ambient calculation in 3R7P1?

[Mark Stock]

Greg,

I am sorry if I am responsible for ruining your weekend. Does the 
benchmark scene look OK to you (exercise the proper calculations, 
include enough interesting stuff to be general, etc.)?

Would it help your work if I ran more cases with older 
Radiance versions?

It's a bummer I missed you all at the conference. Hopefully when 
I get my degree (and a job), I'll be more able to attend.

Thank you.

Mark
