The Institute

Founded in 2005 as part of the faculty of Computer Science, the main mission of the new institute is to build a bridge between two seemingly unrelated research areas: Computer Graphics and Digital Libraries.

The truth is that one of the main reasons for the surprisingly slow uptake of computer graphics as mainstream technology is the semantic gap: Geometric entities (points, triangles, NURBS patches) usually have a distinct meaning (wall, elbow, backrest). However, a 3D-model can also be seen as a generalized document. This change of perspective suggests the transfer of digital library technology to processing, annotation, summarization, indexing, and retrieval of 3D-data.

This new paradigm is explored in a number of national and EU projects.


Research Focus Computer Graphics

  • DAVE: Definitely affordable, high-quality CAVE system (Inffeldgasse 25e) as immersive display system for VR research
  • OpenSG: Scene-graph engine for simulation and animation, synchronized multi-screen rendering
  • GML: Generative design of procedural shape, with runtime system that allows interactive parameter changes and multi-resolution rendering

  • Generative surface reconstruction: Extraction of shape parameters by fitting procedural shape templates to low-level geometry (meshes)
  • MRT: Long-standing research and teaching platform for photo-realistic rendering, with ray-tracing, radiosity, photon maps, spatial subdivision, real-time ray tracing, ...
  • CITYFIT: Massive high-quality urban reconstructions by fitting shape grammars to images and derived textured pointclouds

Research Focus Digital Libraries

  • Generalized documents (3D and other media types) as 1st-class citizens in digital libraries
  • Workflow support for electronic documents (e.g., Eurographics Digital Library)
  • Initiator & coordinator of the Strategic Research Initiative V3D2: DFG-Schwerpunktprogramm "Verteilte Vermittlung und Verarbeitung Digitaler Dokumente"
  • PROBADO project (coordination): Content-based indexing and retrieval service for non-textual documents
