Dynamic Navmesh - AI in the Dynamic Environment of Splinter Cell: Conviction
Speaker: Martin Walsh (AI Technical Lead, Ubisoft Montreal)
Date/Time: Thursday (March 11, 2010) 4:30pm — 5:30pm

Format: 60-minute Lecture
Experience Level: All

Session Description
Today's game environments are becoming more dynamic. Whether it be more objects moving around, or fully destructible environments, NPCs need a way to deal with the changing state of the environment in an intelligent manner. With just a few objects moving around, standard avoidance algorithms worked well, but with the complexity of this generation of games, a more sophisticated approach is necessary.

The goal of this session is to present to the approach used on Splinter Cell: Conviction to deal with dynamic environments: The Dynamic Navmesh. The attendee will be shown the initial solutions developed to implement the fundamental Dynamic Navmesh operations, why some of them failed, and the final solutions we came up with. Along the way many performance and robustness issues were encountered. Some of those will be presented as well, along with the solutions developed to overcome them.

Intended Audience
This lecture is intended primarily for AI programmers. However technical directors or any game developer involved in a project featuring a dynamic environment should find this presentation interesting and informative.
