Résumé: Dealing with synthetic actors who move and behave realistically in virtual environments is a task which involves di!erent disciplines like Mechanics, Physics, Robotics, Arti"cial Intelligence, Arti"cial Life, Biology, Cognitive Sciences and so on. In this paper we use the nature of the information required for controlling actors' motion and behaviour to propose a new classi"cation of synthetic actors. A description of the di!erent motion and behaviour techniques is presented. A set of Internet addresses of the most relevant research groups, commercial companies and other related sites in this area is also given.
