Research Interests

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
  • Web-based visualization for mobility analytics
  • Interactive software maps

We also offer topics for master theses

Interaktive, multiperspektivische Ansichten für geovirtuelle 3D-Umgebungen

Lorenz, Haik; Trapp, Matthias; Döllner, Jürgen in Kartographische Nachrichten 2009 .

In diesem Beitrag werden Visualisierungstechniken vorgestellt, die auf den Gestaltungsprinzipien von Panoramakarten und Detail- und Überblicksdarstellungen beruhen. Die Techniken generieren multiperspektivische Ansichten für geovirtuelle 3D-Umgebungen, insbesondere für zwei häufig benötigte Ansichtsformen, die Vogelperspektive und die Fußgängerperspektive. Die Techniken tragen dazu bei, die Bandbreite der computergestützten, interaktiven 3D-Darstellungen zur Visualisierung von virtuellen 3D-Raummodellen zu erweitern und die Effektivität raumbezogener Informationsdarstellungen im Hinblick auf Ortsbewusstsein und Informationsgehalt zu verbessern.
