[Radiance-general] Calculate DGI with Radiance through Ecotect

[Jan Wienold]

Hi Maria,

you can also use evalglare to evaluate glare within (fish-eye) images.
Besides DGI, it calculates also the Daylight Glare Probability DGP, 
which might be a more reliable glare evaluation method than the DGI.

If you have non-fish-eye images only, it is from my point of view very 
difficult to get a reliable glare evaluation since you miss parts of the 
field of view.

You can download evalglare here - a short description is within the zip 
file:
