Show HN: Demo of Agent Based Model on GPU with CUDA and OpenGL (Windows/Linux)

What exactly is an "agent based model" in this case? What I see is a lot of triangles moving around, but what exactly drives them?

Hi, thank you for your interest. Agent based model is a term refers to an interaction between multiple object (called agent) with its own property. The triangle is one agent in this case and in this example it moves along a random trajectory (just like people in a crowd). Each triangle also has its own color of its population so agents in the same population will have the same color.

Are the agents independent or are they affected by neighbors? It would be nice to see some classic ABM examples like wolf-sheep population, flocking, and wildfire spread to demonstrate the utility of this.

You should work on inter-agent interaction next! It's so much fun.

I have played with this a fair amount and put a couple of my experiments in a repo- both slime mold simulation and "particle life".
