Abstract

In current city visualisations crowds are being included to increase realism in the scene. With the self-steering nature of crowds it is traditionally difficult to control the number of humans that could be in view at any one time. While rendering speedups have been successfully applied for many years, this paper takes another approach with the aim to keep a steady frame rate. We attempt to influence the crowd dynamics to maintain the frame rate, without this becoming apparent to the user. We show how this work can be applied to a virtual reality tour of a medieval town.
