Hi Jean,
Glad you started this one. It's been makin me think.
Faster is better? Well, that's a no brainer! :)
I went looking for info on the difference between scanline and
raytracing and found...

Interesting thought. Daniel said the same, "...it seems to me that
"normal" raytracers are slower, because they try to approximate real
physical behavior of light & materials in order to allow you to create
virtually every look, while game-engines often "fake" real life looks
through clever use of texture maps.." Ya, "all 3D is fake." But that,
and the issue of video game "reality" leads me to another consideration
regarding what I'll call the 'Physics of Composition'...
I'm not sure if I have my facts straight, but... Does HDRI work because
it better simulates reality by simulating better reflections and subtly
shifting tonal values, or because it raises the key value of the
hi-lights on the object, therefore creating a "brighter" attractor for
the eye, thereby re-enforcing the way we see, which is not staring by at
one spot for a long time, but by scanning, moving over an object
capturing snap shots, that the brain then processes into a single
experience.
Watching the battle scenes in the newest three Stars Wars movies drove
me crazy (Mia Culpa. Mia Culpa :) cause they were way too busy, not
leading the eye to re-enforce the drama. And were way too crystal clear
in render quality, not like when we focus on a particular object how
other fields in our vision blur. (And not just because my eyes have
been getting fuzzyier the last couple of years. :)
Whats my point? Ya, more speed is always better in this game. And more
research into presenting real physics in images is just better and
better and better, cause the better you know reality the better yer art.
But has enough been done in studying the human experience of sight? How
much do we over-work the images we build? Could we be doing more with
less and saving rendering time because of it?
...Or are ya just fed up with the Lambourgini sitting on your desktop
always running in what seems like 1st gear? :)
