Radiance Software

Is anyone a member of the GoodLighting forum, who could field this?

Hello. I run an online lighting Forum GoodLighting.com, and one of our members who uses the Radiance software has posted a question pertaining to its compatibility with Mac OS. It would be nice if someone could answer their question as I am sure many other people have similar questions. You can see the particular thread at http://www.goodlighting.com/showthread.php?t=13.

Thank you for your prompt attention.

Best regards,

Hi André,

I forwarded your question to the radiance-general discussion list, asking if anyone there is on the Good Lighting forum. Since no one responded as yet, I assume they're either busy or the overlap is the empty set. It might behoove you to subscribe to radiance-general at www.radiance-online.org so you can get future questions answered there.

Radiance is well-supported on Mac OS X, and the precompiled 3.8 "universal" binaries with instructions on installation may be found at the main website:


You should download both the complete distribution with source code and the rad3R8_macosx.tar.gz link. Once you unpack the main distribution, you'll want to run "makealll library" from a Terminal window in the main "ray" directory. Then, move the unpacked binaries to a /usr/local/bin or similar directory and add this to your shell's path. Radiance is a suite of command-line tools, so if you are unfamiliar with Terminal and X11, they will undoubtedly give you trouble.

The best reference for the system is still "Rendering with Radiance," edited by Larson and Shakespeare. Charles Ehrlich, the author of the lighting chapter, worked diligently to make this book available through a print-on-demand service, which seems to have dropped us at the moment, so getting a copy is problematic. I suggest you write to Amazon (see <http://tinyurl.com/ycajwm>) or BookSurge.com telling them you would like one if you don't have the book already.

Best of luck.


Mac Intel OS X lighting calc software - 01-22-2007, 12:50 AM

So, I've switched to a Mac Intel, running AutoCAD with no problems, all is well in the world.

Seeing how OS X is Unix based, has anyone installed Radiance on their machine (with success, of course)? Can you talk me through it? Having switched (happily, I might add) to Mac recently, I have no Unix experience and am looking for some guidance.

Thanks in advance!
