Are the crowds portrayed in this image generated by a particle system of sorts? I bet this tool would be useful for, say, evacuation simulations where building planners would like to validate if they've created enough space for large groups to exit the building in case of an emergency.

I looked into the topic a bit further, and it looks that there's a lot of math behind simulating the behavior of each agent/particle! For the example I proposed above, there could be a stress-based model as denoted in this article: https://en.wikipedia.org/wiki/Crowd_simulation#Stress-based_model

@micahtyong thanks for sharing! In animated Pixar movies, crowds will be simulated initially, then some individual characters in the simulation will be "promoted" to characters and manually animated to adjust the appearance of the scene.
