The emit parametr, used for the radiosity computation,
have a scientific sense?
It’s relative to candela, lumen or Lux or other photometric
unit ??
thx,
ManuelI may be all wet on this (or maybe I’ve failed to see the light 
) but I’ve had the impression that the values in Blender were largely relative units. If any of them have real world absolute value counterparts, I haven’t found them.
It might be interesting to run a test, in which one sets up the conditions to measure lux, but do it in Blender, and see what the results are. Or is that possible?
I admit to being a physicist by training, but it’s been a lot of years since those courses!
Mhhh I’ve found this (not exatly related to radiosity) but it don’t work…
This a great documentation about Radiosity and human perception:
and if you look the page 10 of this
http://tralvex.com/rover/tralvex-thesis.pdf
you see the fundamental quantities concerned with the measurement of the light and the relation with radiosity…in the chapter 2 “Radiometry and Photometry”
I try to read this, but my english is not exactly good, and this
is a very hard documentation…can you take a little look too?
cheers,
ManuelThanks Manuel, This looks very interesting. Now to get the time to read it.
Paradox
Ok…I’m waiting 
If I make a little progress, I post here…
