Welcome on the homepage of the chair "Computer Graphics Systems" of Prof. Jürgen Döllner and his team. We like to inform you about our teaching and ongoing research activities in the analysis, planning and construction of computer graphics and multimedia systems.
Matthias Trapp currently works as a post-doctoral researcher, lecturer, and head of the research group '4DnD-Geovisualization' (InnoProfile Transfer Initiative) at HPI, Computergraphics Systems Chair. His research interests include the following topics:
GPU-based image and video processing techniques and frameworks
Interactive GPU-based rendering techniques for massive spatio-temporal data
Focus+context visualization techniques for 3D virtual environments
Concepts for Automatic Generalization of Virtual 3D Landscape Models
Glander, Tassilo; Trapp, Matthias; Döllner, Jürgen
This paper discusses concepts for the automatic generalization of virtual 3D landscape models. As complexity, heterogeneity, and diversity of geodata that constitute landscape models are constantly growing, the need for landscape models that generalize their contents to a consistent, coherent level-of-abstraction and information density becomes an essential requirement for applications such as in conceptual landscape design, simulation and analysis, and mobile mapping. We discuss concepts of generalization and working principles as well as the concept of level-of-abstraction. We furthermore present three exemplary automated techniques for generalizing 3D landscape models, including a geometric generalization technique that generates discrete iso-surfaces of 3D terrain models in real-time, a geometric generalization technique for site and building models, and a real-time generalization lens technique.
