Abstract
This Chapter discusses the methods involved in the generation of large crowds of Virtual Humans in environments like cities. We focus on the geometric aspects of these methods in the different steps involved: scaler, simulator, renderer, path planner, and behaviour handler. We emphasize the application of these methods to the field of Cultural Heritage, recreating old cities with population living their life. In particular, we present examples from Pompeii and discuss the interaction between the environment and the behaviour of the Romans.
