BTW, I know you know what I am talking about, 90% of what we have as "argument" here is semantics. But, to be honest, I don't care if I change a thought or word in what you have written. I do care that those who read this have a basic understanding of the render processes - algorithms be damned. So, if I have oversimplified some things for the sake of clarity, as I have said, we will clean those up as we go along...we have the opportunity to make this an extraordinary discussion about rendering and raytracing. But let's try to make it so someone can follow it from square one forward...

And, second request, can we be civil?
