Okay, I know this thread might be... well, weird. And pointless, but... I was "enlightened" a few days ago... And thought that I'd share this "enlightenment" with someone... So. Here it goes:
Every game engine so far uses objects, segments, lights, etc, or something similar as far as I know. So... I thought, what if all those would be "wiped out" and... everything would be made of small bits, that would be attached to each other with "strings", so everything could move without them being animated, and there would be perfect physics on everything, etc!
And the same would be with lights, but a little differently:
Every light ray would be made of small, almost transparent bits that would have no collission.
So they would "blend" in the environment, and there would be natural shadows on everything, etc.
It would be so DAMN AWESOME.

...but impossible? But well, anyway...
Discuss, people.

(but don't be mean to me as I have no slightest clue about if it'd be possible
