Arch-Explore: A natural user interface for immersive architectural walkthroughs
Found in: 3D User Interfaces
By Gerd Bruder, Frank Steinicke, Klaus H. Hinrichs
Issue Date:March 2009
pp. 75-82
In this paper we propose the Arch-Explore user interface, which supports natural exploration of architectural 3D models at different scales in a real walking virtual reality (VR) environment such as head-mounted display (HMD) or CAVE setups. We discuss in ...
Physical Design Aspects of an Object-Oriented Geo-Database Kernel
Found in: Database and Expert Systems Applications, International Workshop on
By Andreas Voigtmann, Ludger Becker, Klaus H. Hinrichs
Issue Date:September 1997
pp. 529
GOODAC is an object-oriented database core supporting the implementation of GIS-applications which is realized on top of the database system ObjectStore. We present aspects of the physical design of GOODAC and discuss our concepts for index structures, log...
Constraints and Triggers in an Object-Oriented Geo Database Kernel
Found in: Database and Expert Systems Applications, International Workshop on
By Hendrik Ditt, Andreas Voigtmann, Ludger Becker, Andreas Voigtmann, Klaus H. Hinrichs
Issue Date:September 1997
pp. 508
A concept to integrate constraints and triggers into the object-oriented geo database kernel GOODAC is presented in this paper. We propose an extension of GOODAC's object definition language to include the definition of constraints and triggers within the ...
Natural Perspective Projections for Head-Mounted Displays
Found in: IEEE Transactions on Visualization and Computer Graphics
By Frank Steinicke, Gerd Bruder, Scott Kuhl, Pete Willemsen, Markus Lappe, Klaus H. Hinrichs
Issue Date:July 2011
pp. 888-899
The display units integrated in today's head-mounted displays (HMDs) provide only a limited field of view (FOV) to the virtual world. In order to present an undistorted view to the virtual environment (VE), the perspective projection used to render the VE ...
Overlaying simply connected planar subdivisions in linear time
Found in: Proceedings of the eleventh annual symposium on Computational geometry (SCG '95)
By Klaus H. Hinrichs, Ulrich Finke
Issue Date:June 1995
pp. 119-126
An interactive visualization of weighted three-dimensional α-hulls is presented for static and dynamic spheres. The α-hull is analytically computed and represented by a triangulated mesh. The entire surface is computed and displayed in real-time ...
