Edit: I'm surprised to not find anything when I try to find projects that try to use Apache Arrow in unity 3d. Seems to be a lot of interesting potential in leveraging various simulation libraries in game like applications.
Edit2: Ah, probably because something like waterlilly would have to be rewritten quite a bit too use arrow.
I wonder if there's a way to share the data buffer across languages. Would be neat if it was feasible to use the real time model data in a game.
