Hi, Marija, some recent discussions on "*solid angle as represented by each
pixel* in an image produced by Radiance" from Lars and Giulio in the
following thread may also be helpful:

Maybe this can help you:
you can use the pcomb program to obtain the solid angle of each pixel of a
picture!
for instance this will translate a radiance picture (origin.pic) into a
"solid angle" picture (solid_angle.pic) where each pixel has a brightness
value that matches the solid angle of the same pixel in the original
picture:
pcomb -e 'lo=S(1)' origin.pic >solid_angle.pic

Hi,
Thanks Raphael and Ji.
S(n) function is definitely what I needed.
Now I 'just' need to analyze C code to see how calculation is exactly done.
Thanks again,
Marija.
