Crowds and Pedestrians without Bumper-Car Syndrome

Ken Perlin, Jean-Charles Perrier, et al. on August 25, 2010

While animation and navigation technology has matured significantly over the years, combining the two together remains quite a challenge! Games like HEAVY RAIN include scenes with few pedestrians that must avoid each other (e.g. on a sidewalk), as well as huge groups that form the illusion of a crowd (e.g. in the station). What techniques are used to implement such situations, and how can the results be improved?

In this all-star panel from the Paris Game AI Conference 2010, you'll hear different perspectives on the problem, from the programming team at Quantic Dream (Bertrand Faure, Jean-Charles Perrier) to leading researchers on procedural animation (Ken Perlin), and one the best independent AI developers (Mikko Mononen)! With their combined wisdom you'll hear solutions to the crowd problem compared to smaller groups of agents, and the best way to integrate it with character animation.
