SIGGRAPH Asia 2008 (1 of 2) - Interaction Patches for Multi-Character Animation

Hubert Shum, Taku Komura, Masashi Shiraish and Shuntaro Yamazaki

We propose a data-driven approach to automatically generate a scene where tens to hundreds of characters densely interact with each other. During offline processing, the close interactions between characters are precomputed by expanding a game tree, and these are stored as data structures called interaction patches. Then, during run-time, the system spatio-temporally concatenates the interaction patches to create scenes where a large number of characters closely interact with one another. Using our method, it is possible to automatically or interactively produce animations of crowds interacting with each other in a stylized way. The method can be used for a variety of applications including TV programs, advertisements and movies.
