This freedom is what made it possible to make my light meter.
In the light meter, I use a Diffuse node and the tuple it produces represents the diffuse reflection at that point on the object, based on available incoming light color and direction, the angle of the surface normal, and the angle to the observer (camera). This value is a color that normally gets used to color a pixel or at least adds to the color of a pixel.
But in the light meter, I convert that to a number, and I use that number to decide HOW BIG A DOT TO DRAW!!!!
I also use that to decide to replace the dots with yellow (almost too bright) or red (definitely too bright) - the diffuse node in this shader has little to do with diffusely reflecting light. So just because that's its official job, doesn't mean I have to use it that way.
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
