[Radiance-general] under water light fixtures

[John Mardaljevic]

Hi Christoph,

> how to model light traveling through water

If you mean seeing the beam that results from scattered light, then  
you'll need to use the mist material.  Check out Section 8.4.2 (p  
457) in RwR.  I recall seeing somewhere that the mist material is  
also implemented in pmap.

Cheers,

-John
