Crowd Simulation of Pedestrians in a Virtual City
Crowd simulation is an important aspect of the computer graphics ﬁeld. Virtual crowds are integrated to ﬁlm scenes, computer games, architecture, urban modelling and many other areas. Typical implementations simulate battle scenes, emergency situations, safety issues or add content to virtual environments. However few systems simulate autonomous pedestrian crowds in a normal setting desired in virtual environments such as conﬁgurations produced by a TextTo-Scene conversion system. We present a crowd simulation behavioural model for simulating identiﬁed crowd phenomena in a virtual city such as street ﬂows, crowd formation and road crossings. We propose a three-tier architecture model to produce intentions, perform path planning and control movement. We demonstrate that this model produces the desired behaviour associated with pedestrian navigation in a virtual city, which includes navigation, ﬂow formation , circle creation and passageway crossing.
