Hi Owen, we've done some work using Processing to do 3D visualization in
NetLogo -- both by opening an Processing window from a running NetLogo model
and by running NetLogo headless from a Processing program (and doing real-time
visualization of the running model). Of course, NetLogo uses Processing for
some of its built-in 3D visualization, but the version is somewhat old and I
don't think Uri et al have put much effort into the 3D side of things recently,
so our approach gives a bit more flexibility. I'm happy to share the paper we
put together on it if you or anyone else is interested.
The question of what a 3D ABM is actually useful for is surprisingly more
challenging. We put together a simple dynamic network model and used the 3D to
visualize the connections between and movement of the nodes from one state to
another (of 3 possible states), so we had something like a sandwich of dots
with lines that we could rotate around and zoom in on. It was something that
made it a bit easier to understand what was going on in the model and between
the nodes -- more a reporting mechanism than an inherent part of the model.
Well, that, plus it looked cooler.
Using 3D as an inherent part of the model's behavior is another thing entirely.
In that case, the model would require the physical 3 dimensional location of
each agent (and the environment) to be critical to the behavior of the agents
-- and something that couldn't be easily represented in 2D with the 3rd
dimension handled separately. We started to look at using animation software,
such as Maya, to do the modeling, but didn't make much progress before our
animator moved on. Maya or 3DS Max allow for Python programming, but it isn't
exactly ideal for ABM work.

Hi Pietro, great to hear from you. Lets try to get together next time I travel
to Italy. I generally stay in Camerano, near Ancona, but often spend time in
Venice with Fabio or lately in Padova .. so we'd not be that far apart via
train.
SLAPP is quite nice. I wonder if you would be interested in a NetLogo inspired
JavaScript ABM framework: http://agentscript.org. I need help thinking about
its future.
I'm taking a break from it for a while, diving into a webgl mooc given by Ed
Angel based on material from the latest edition, 7, of his Interactive Computer
Graphics text .. all using webgl.
Here's the url of the mooc if you'd like to follow along:
https://www.coursera.org/course/webgl
A major goal for a few of us is how to move ABM to 3D. We spoke with Uri and
Seth at NetLogo and they hadn't enough time to really research how to best use
3D.
Great to hear from you.
-- Owen

Dear all,
sometimes I reappear ...
My experience is very positive, with https://github.com/terna/SLAPP and
GitHum program in my Mac.
Best, Pietro
