Ongoing Projects

		Point-Cloud Processing with Primitive Shapes 3D acquisition devices usually produce unstructured point-clouds as primary output. A challenge in this context is the decomposition of the point-cloud data into known parts in order to introduce abstractions of the originally unorganized data. This information can be used for compression, recognition and reconstruction.

		Efficient Rendering of Landscapes This project aims at methods for view-dependent realtime visualisation of city models with details up to single cm close to the viewer. Apart from supporting the realtime visualisation the employed LoD hierarchies should also support accentuation and abstraction of semantic information.

		Last Mile In the scope of the Last-Mile Project we are carrying out research on interactive visualisation of potential tsunami hazards via networks.

		SCARPED: Scalable Compression And Rendering of Phototextured Elevation Data The tremendous amount of data acquired via remote sensing or airborne sensors provide the basis for a photorealistic rendering of ample landscapes, even from close-by viewpoints. This projects aims at a realtime exploration of such arbitrary-sized datasets without sacrificing visible detail.
