[Radiance-general] evalglare with regular lens

[Rob Guglielmetti]

Hi Ery,

Problem is, evalglare uses the daylight glare probability metric in its calculations, which by definition takes an angular fisheye HDR image as input. I think the images in the Harvard tutorial are for clarity and were not used for the calculation of the DGP. Hopefully Jan, Christoph, and Alstan can weigh in here on some clarification and some alternatives.

The evalglare description says that it only accepts fisheye images. There is a tutorial from Harvard GSD (Doyle and Reihart) that shows a non-fisheye photo in evalglare: http://www.gsd.harvard.edu/research/gsdsquare/Publications/HDR_III_Evalglare.pdf
