[Radiance-general] Working plane

[sasa.cemesova at tiscali.co.uk]

Dear all, 

I am an undergraduate student trying to model a 10m x 10m room with 
one corner touching the origin and a window on the south facing wall. I 
have been trying to model this room with a film of translucent white 
plastic on the window, and am really really stuck and need help 
urgently, any advice would help a lot! 

Firstly,  I have a translucent white plastic material with a 
reflectivity value of 0.518 and Transmissivity value 0.046, how would 
you do the parameters for this material? 

secondly, I have a model set up, and I really need to get a working 
plane with lux values on it, how do you do this in either Control Panel 
or radiance itself? I have tried to use Ecotect, but it doesnt seem to 
be able to model a translucent material very accurately. 

Thank you for your time in advance, 
Sasa
