 Central aim of organisation
Maintaining sustainable semantics of 3D datasets

 Briefly describe your organisation
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
