[Radiance-general] glaze script limitation

[Jack de Valpine]

Hi Greg and Francois,

Greg, would it work to just make sure that one surface of any layer is 
"uncoated" (eg where Rf ==  Rb perhaps withing some small error range) 
rather than "clear"? Thus allowing for different clear/uncoated glass to 
be used as surfaces on different layers?

You would have to "lie" and tell the script that one of your two surfaces was glass, then pick your new entry as the other surface, but the result should be accurate.  The glaze script actually ends up using the specified non-glass surface parameters in its calculations -- the glass surface is just there as a reference.

We probably should offer an option to enter custom transmittances and front&  back reflectance values for advanced users, and this wouldn't be too difficult to add.  I wonder if we could take pasted output from Optics, directly?  I don't know if they have a format that gives us the naked data, but I suppose we could extract it from the Optics output for Radiance.
