    Interactive city generation methods



    In this sketch we present an interactive real-time city generation system. The aim of such a system is to apply procedural techniques to rapidly generate detailed city models suitable for use in graphics applications. Most commonly, the underlying road network for the city is generated first and is used as a basis for positioning buildings and other features. Existing work includes CityEngine [Parish and Müller 2001] which uses geo-statistical image maps and L-systems to generate road networks. Other researchers have employed agent-based simulation of land use [Lechner et al. 2004], or templates encapsulating common road patterns [Sun et al. 2002].
