Anti reflective coated glass

radiance-general
1

Hi group,

I am working on a model of a shopping mall where we have to compare the visibility of the interiors using 'normal and anti reflective glass.
( we have a sample of LUXAR Anti reflective coated glass here, but no equipment to measure ).
Does anybody has experience with simulating reflective and non-reflective glass?
Some values for the glass primitive or BRTDF func would be very helpfull.

Iebele

PS:
from the glaze csh script, which seems very usefull, I can choose from these 5 surface types.
Is any of these "non reflective" ?

   1 - clear glass
   2 - VE1-2M low-E coating
   3 - PVB laminated
   4 - V-175 white frit
   5 - V-933 warm gray frit

You could set the index of refraction of the Radiance material type glass to someting fairly low:

void glass anti_r
0 0 4
.6 .6 .6 1.3 or whatever

Hi Martin,

I've never thought about a relation between reflection and refraction.
Thanks for the hint. It does the trick for now.
