The aim of this thesis was to eliminate essential deficits in the use of previous 3D GIS in an openly distributed GIS infrastructure. The increasing availability of three-dimensional city models poses a special problem, ...

This work was conducted at the Darmstadt University of Technology, essentially between 1998 and 2002. Before and during this period, I was working at the INI-GraphicsNet, Darmstadt, first in the Zentrum für Graphische ...

Two ingredients are necessary to synthesize realistic images: an accurate rendering algorithm and, equally important, high-quality models in terms of geometry and reflection properties. In this dissertation we focus ...

In this thesis we discuss the representation of three-dimensional scenes using image data (image-based rendering), and more precisely the so-called light field approach. We start with an up-to-date survey on previous ...

In this dissertation, I describe a virtual head model with anatomical structure. The model is animated in a physics-based manner by use of muscle contractions that in turn cause skin deformations; the simulation is ef ...
