Brent: way WAY astute observations and info, thanks 10^6! How's this for an idea: follow Ed's Mooc. No need to do the homework etc, just to get informed as to webgl's core capabilities. It's just started and the videos are there for the watching and a standard vocabulary. The GPU is a standard worth knowing.
Then we can (a group of us here interested in the topic .. hopefully Pietro who has a LOT of ABM experience .. as does a lot of Italy) put together some ideas for 3D ABM. Certainly Uri and Seth were interested in it, but didn't have time to do the research. Thus they use 2.5 D "pop-out" for standard NetLogo .. way nice .. and agree that beyond their "cube patches", they hadn't time for enough research into the matter. ABM is basically "data all the way down" with dynamic interaction within the data. 3D fits into this, I think. Maybe we should just think of models that could use 3D? RedFish has a few fascinating ideas in the works like point-clouds as computation.
