Paper Abstract:
|
Virtual crowds are rapidly becoming a standard feature of large scale virtual environments. The incorporation of a virtual
population enhances the realism of these environments. Effective algorithms have been formulated to govern the
movement of individual avatars to give the crowds some semblance of intelligence, but often cover only one part of the
simulation: collision detection, navigation or local interaction. In this paper we introduce a system that combines all three
aspects. The navigation follows density principles suggested by the space syntax methods [9]. Our navigation system can
also be tuned to simulate evacuations. The simulation is non deterministic in the sense that agents do not follow the same
path, but the overall simulated density distribution is consistent. Also, local behaviour is simulated in the form of points
of attraction and small-group (pair) formation which provides more a realistic visualization. Our system runs in real time
allowing interactive visualization. |
