[Radiance-general] evalglare with regular lens

[Thomas Bleicher]

You can use the pinterp program to convert from one projection to another.
See the man page for an example or dig in the archives where this has been
discussed before. However, note that the glare equations are based on a
full hemispherical image. You will have to fill in the missing perimeter of
your converted fisheye image with values of the right brightness or your
glare evaluation will be off.

Thomas
