[Radiance-general] materials in radiance software

Carsten has just reminded me that his fancy materials collection is 
still available on radiance-online.org. He gave a presentation titled 
"Designer's Radiance" at the first Radiance workshop. You can find his 
material here:

Thanks, Carsten!

What you want is the file desradaux.tar which is linked at the very 
bottom of that page.

I also forgot to mention that there are some very simple examples of 
material cal files in my Radiance tutorial, available from this page:
http://www.jaloxa.eu/resources/radiance/documentation/index.shtml

The examples are:
- a blue horizontal stripe across the wall
- random carpet tiles
- dust on the carpet tiles

Those examples are probably a much more accessible starting point than 
Carsten's super complicated granite tiles (which I have never managed to 
fully decipher)

Good luck to you.

Axel
