Here is a longer video showing the obstacle avoidance that these Fish use.
This is the AutoPlayFish game mode, in this mode a camera is strapped to an NPC Fish and you can draw its trace lines with a right mouse click.
This NPC Fish swims to random Water Targets- and everything in-between is obstacle avoidance.
Fish will be $44, and will be available once it makes its way through the approval process- usually a couple of weeks.
I have 161 Fish swimming around in the demo level and I’m getting 56-62 FPS on my mid level Nvidia card (GeForce 970).
