<p>Populated urban environments are important in many applications such as urban planning and entertainment. However rendering in real time many people in a complex environment is still challenging. In this article, we propose methods for rendering real-time animated crowds in virtual cities. We take advantage of the properties of the urban environment, and the way a viewer and the avatars move within it, to produce fast rendering, based on positional and directional discretization. To allow the display of a large number of different individual people at interactive frame rates, we combined texture compression with multi-pass rendering. The results show that we can visualize in real time a city with thousands of animated people.</p>
