Hierarchical Disparity Estimation with Programmable 3D Hardware (2003)
Christopher Zach, Konrad Karner, Horst Bischof
This work presents an implementation of a hierarchical disparity estimation algorithm entirely executed on programmable 3D graphics hardware. In contrast to previous hardware based implementations of...
User-Centric Transfer Function Specification (2003)
Bernhard Reitinger, Christopher Zach, Alexander Bornik, Reinhard Beichel
The quality of a 3D volume visualization heavily depends on a representative transfer function which is responsible for mapping the original density values to color and opacity. Finding a suitable...

User-Centric Transfer Function Specification in Augmented Reality (2003)
Bernhard Reitinger, Christopher Zach, Alexander Bornik, Reinhard Beichel
The quality of a 3D volume visualization heavily depends on a representative transfer function which is responsible for mapping the original density values to color and opacity. Finding a suitable...
Fast Event-Driven Refinement of Dynamic Levels of Detail (2003)
Christopher Zach, Konrad Karner
Dynamic levels of detail allow fine grained selection of actually rendered geometry suitable for the current viewing parameters. Therefore, the visual quality of interactive 3D applications is...
Optimized Stereo Reconstruction Using 3D Graphics Hardware (2003)
Christopher Zach, Andreas Klaus, Bernhard Reitinger, Konrad Karner
In this paper we describe significant enhancements of our recently developed stereo reconstruction software exploiting features of commodity 3D graphics hardware. The aim of our research is the...
Multiple Eigenspaces for Hardware Accelerated Image (2003)
Markus Grabner, Horst Bischof, Christopher Zach, Andrej Ferko
We present a novel hardware accelerated method for rendering images of a 3D scene. The method uses the recently proposed multiple eigenspace method to obtain an e#cient representation of rotated...
Texture Mapping for View-Dependent Rendering Mario Sormann (2003)
Mario Sormann, Christopher Zach, Konrad Karner
View-dependent multiresolution meshes allow smooth interactive animation and optionally time-critical rendering of huge geometric data-sets and are therefore an important tool for large-model...
Progressive Compression Of Visibility Data For View-Dependent Multiresolution Meshes (2003)
Christopher Zach, Konrad Karner
In this paper we present a lossless and optionally lossy compression method for precomputed visibility data for view-dependent multiresolution meshes, which supports out-of-core rendering and...
Progressive Compression Of Visibility Data For View-Dependent Multiresolution Meshes (2002)
Christopher Zach, Konrad Karner
In this paper we present a lossless and optionally lossy compression method for precomputed visibility data for view-dependent multiresolution meshes, which supports out-of-core rendering and...
Modeling and Visualizing the Cultural Heritage Data Set of Graz (2002)
Christopher Zach, Andreas Klaus, Joachim Bauer, Konrad Karner, Markus Grabner
The inner city (Old Town) of Graz will be the European cultural capital in 2003. In this paper we present preliminary results on the reconstruction and visualization of this kind of cultural heritage...
Time-critical Rendering of Discrete and Continuous Levels of Detail (2002)
Paul Debevec, Simon Gibson (editors, Christopher Zach, Stephan Mantler, Konrad Karner
We present a novel level of detail selection method for real-time rendering, that works on hierarchies of discrete and continuous representations. We integrate point rendered objects with polygonal...
Integration of Geomorphing into Level of Detail Management for Realtime Rendering (2002)
Realtime rendering of scenes with discrete levels of detail (LOD) often suffers from noticeable visual changes between succesive frames. We propose geomorphing to obtain smoother animations while...
Prefetching Policies For Remote Walkthroughs (2002)
Christopher Zach, Konrad Karner
We present a 3D data streaming approach for remote walkthroughs, that integrates local optimization techniques for realtime rendering with prefetching techniques for remote scene graphs. Especially...
From Real Cities to Virtual Habitats (2002)
Christopher Zach, Andreas Klaus, Joachim Bauer, Konrad Karner
This paper outlines the workflow from terrestrial and aerial images of urban areas to the reconstructed virtual models and the corresponding visualization. We combine new ideas as well as known...
