My point was that if I use real meaningful units I can verify that the
integration works properly. For example: if I have a theoretical light
source emitting certain power and a perfect lambertian surface, I can
check if the surface reflects the correct radiance. I didn't mean that I
would necessarily get more photorealistic images with those units. Well,
actually, I will, if using real units helps to solve errors.

Now I don't specify light sources that way and I can't verify the
results (and I do have some very possible errors now in the code...). I
only get pretty images and that is only half the fun :)
