What is Radiance ?
If you happen to find yourself back accidentially on this site, you know now what Radzilla is about: Alternative versions of Radiance rendering programs with a GUI frontend. But what is Radiance?Well, I won't explain this here, as it has already been done elsewhere, so in typical www-manner some links follow to get you started. Especially those who have heard about Radiance already so many times and always wanted to check it out ... isn't it a good time to do so right now?
Probably the best point to start is the Radiance knowledge base site run by Peter Apian Bennewitz:
www.radiance-online.org
which provides download options for the main distribution (via CVS or as tarball), furthermore it contains mailing lists, archives, links, almost everything about Radiance and Radiance development.
Of course there's also the original
Radiance homepage
and a link to 'The Book' by G.Ward/R.Shakespeare and others, dealing with, well, the title says it :)
