Procedural Modeling of Cities
Proceedings of ACM SIGGRAPH 2001
Abstract: Modeling a city poses a number of problems to computer graphics. Every urban area has a transportation network that follows population and environmental influences, and often a superimposed pattern plan. The buildings appearances follow historical, aesthetic and statutory rules. To create a virtual city, a roadmap has to be designed and a large number of buildings need to be generated. We propose a system using a procedural approach based on L-systems to model cities. From various image maps given as input, such as land-water boundaries and population density, our system generates a system of highways and streets, divides the land into lots, and creates the appropriate geometry for the buildings on the respective allotments. For the creation of a city street map, L-systems have been extended with methods that allow the consideration of global goals and local constraints and reduce the complexity of the production rules. An L-system that generates geometry and a texturing system based on texture elements and procedural methods compose the buildings.

Design und Implementation einer
Preprocessing Pipeline zur Visualisierung prozedural erzeugter Stadtmodelle
Master's Thesis (Supervisor: Prof. Markus Gross), Computer Graphics Laboratory ETH Zürich, 2001
The content of my diploma thesis corresponds more or less to the paper. In fact, the diploma thesis is a longer (and thus more accurate) version of the paper. In the latter can be found more information about the procedural shaders while the thesis goes more into detail concerning the 'procedural modeling of buildings' subject.

Prozedurales Modelieren einer Stadt
Semester Thesis (Supervisor: Prof. Markus Gross), Computer Graphics Laboratory ETH Zürich, 1999
My first semester thesis at ETH Zurich was the birth of the CityEngine. I developed the self-sensitive L-Systems with some street rules and thus gave a proof of concept in terms that the streetnetwork generation with L-Systems works. Oh well, in these days, I didn't implemented yet a underlaying reaction-diffusion model... but hey, I was young and needed the graphics :) ... I didn't generate lots of renderings but concentrated on the real-time stereo visualisation by using VR tools in the ETH's interdisciplinary visualisation dome called VisDome (located in the dome of the ETH Zurich main building).
