functional language

Thanks Ignacio! That did the trick. Now then: where is the best place to
look for info on this functional language?

Rob,

Good idea, the functional language is still something of a mistery, also
coverage of it in 'rendering with radiance' isn't over elaborate. Even
though you would have some notion on how it operates, some examples would
give quite some insight in the matter. How about a .cal repository, linked
from the Radiance Wiki, explaining would they actually do? That could give
some insight into the bowels of Radiance?

Cheers,

Jelle.

//Cool to see xshowtrace & related issues coming by this list again, its
really a insightful!

Definitely check out that filefmts.pdf, and the .cal files that come with
Radiance. And Jack's right, some of the esamples on the pcomb manpage are
somewhat enlightening as to hoe this all works. But yeah, zen is
required. I'm not there yet.

Also, the function that started this conversation, WE, is not listed in
filefmts.pdf, nor do I see it in rayinit.cal. Where the heck is it?

Hi Rob,

WE - White Efficacy, it is in the man page for pcomb. There are a lot of variables floating around in the man page so it is a bit hard to find on the first read or 10.

Ah! Thanks. Learning a lot today...

Hi Rob et al.,

The pcomb(1) man page really needs to be reformatted. Originally, there were just a couple of special-purpose variables for this tool, but I kept adding more and more and sticking them in the man page until I couldn't find anything there when I looked for it there, myself. I'll see if I can get around to reformatting it tomorrow.

Regarding "fileformats.pdf," this was a hopeful chapter in RwR along with the most essential reference manual ("refman.pdf") and a source tree guide, but the book was getting to long for Morgan Kaufmann so they were all relegated to the CD-ROM, along with all the man pages. (I don't think anyone really wants a full book of Radiance man pages as part of the text, so that's OK.) The materials description file ("materials.pdf") is also important reading for anyone who is doing critical work on Radiance materials.

Another basic introduction to Radiance and its uses is given in the lecture notes files "backgrnd.pdf", "analysis.pdf" and "rad.pdf". These files as well as the above are of course linked on radsite:

Some of these materials are a bit dated, but that comes with the territory....
