I was expecting to hear back about compile problems from a number of people by this point, but so far the airwaves have been silent. Either 3.7 is compiling flawlessly in a lot of unexpected places, or everyone's too busy enjoying their summers to have given it a try.
Nevertheless, I found one rather serious bug in the new Russian roulette sampling code, urging me to post a patch release, which is now available from:
I have also recompiled everything under Linux, FreeBSD, and Mac OS X. These files have not been posted as yet on radiance-online, as Peter A-B is off on vacation for the week. I expect he'll get around to it before too long, and meanwhile the HEAD dump will be very close to 3.7.1 (if not identical).
I hope to see some of you at the Radiance workshop next week.
