Also take into account what reflectance the surface (-s) have, the size of the space.

I'm measuring directly off the light source. Its diffuse color is (0,0,0) so that it doesn't pick up any extra light.

Keep in mind that the calculations use the centre of the light source as origin, thus using a surface of 1x1m may not be accurate.

I'm not sure what you mean by that? Surely it's just a scaling factor and the illumination is even across the plane?

Point light calculation employs the inverse square law, it gets progressively weaker the further it is measured form the origin.

The light origin is taken as the center of of the light source.

There are no point lights in Indigo.. ?

The term "point light calculation" refers to the mathematical method which electrical / lighting / illumination engineers use.

Hi Juju,
THis would be cool to add, we just have a lot of stuff to do right now.
Maybe after 4.0 is done.

** cough cough ** BUMP

Now that we have render channels, maybe this could be a thing!
