Research Interests

3D Geospatial Rendering

Rendering of and interaction with large-scale 3D data derived from photogrammetric reconstructions or laser scans. Runtime integration of multiscale data from kilometer to sub-milimeter range.


Visual Analytics

Strong interest in domain-specific design of visualizations for supporting domain experts in exploring, analysing, and interpreting heterogeneous data. Domain experience in:
Planetary Science & Geology, Urban Planning, and Tunnel Surface Documentation.


Integration of 3D geometric and attribute data

Efficient and intuive integration to allow users to seamlessly switch between 3D real-time rendering views and 2D visual analysis views, including mutual embedding.


Knowledge Communication

Communication of research results and goals, or technical knowledge in oral and written form for audiences with various expertise, including peers, domain experts, customers, and the general public.

PRo3D - Planetary Robotics 3D Viewer

PRo3D, short for Planetary Robotics 3D Viewer, is an interactive 3D visualization tool to allow planetary scientists to work with high-resolution 3D reconstructions of the Martian surface.

PRo3D aims to support planetary scientists in the course of NASA's and ESA's missions to find signs of life on the red planet by exploring high-resolution 3D surface reconstructions from orbiter and rover cameras. The reconstructions are provided by our partner Joanneum Research.

TSID - Tunnel Surface Inspection and Documentation Viewer

TSID is the 3D viewer component integrated in Dibit8, an application for the inspection and documentation of large infrastructure tunnels developed by Dibit Messtechnik GmbH

We visualize surface reconstructions derived from laserscans and high-resolution images provided by our partner Joanneum Research. Our solution comprises a suite of tools to virtually measure and annote high-resolution tunnel surfaces identifying sub-milimeter cracks and calculate the volume difference between construction phases.
