A crowd is not only a group of many individuals: crowd modeling involves problems arising only when we focus on crowds. For instance, collision avoidance among a large number of individuals in the same area requires different resolving strategies in comparison with the methods used to avoid collisions between just two individuals. Also, motion planning for a group walking together requires more information than needed to implement individual motion planning. This Chapter presents the related works on the subject of groups and crowd simulation as well as discusses the requirements to model behaviors of groups and crowds of virtual actors; current applications, recently applied approaches and challenges of crowd simulations are described.
