OpenManip: An Extensible Cross-Scene-Graph Framework for Direct Object Manipulation
(The Eurographics Association, 2003)
In this paper we describe a framework that exploits 3D widgets in order to allow for the direct manipulation of scene graph objects. The design of the frameworks is inspired by the OpenInventor manipulator functionality, ...
Shadow Mapping Based on Dual Depth Layers
(Eurographics Association, 2003)
Shadow maps are a widely used means for the generation of shadows although they exhibit aliasing artifacts and problems of numerical precision. In this paper we extend the concept of a single shadow map by introducing dual ...

Cell Projection of Convex Polyhedra
(The Eurographics Association, 2003)
Finite element methods commonly use unstructured grids as the computational domain. As a matter of fact, the volume visualization of these unstructured grids is a time consuming task. Here, the fastest known object order ...
Smart Hardware-Accelerated Volume Rendering
(The Eurographics Association, 2003)
For volume rendering of regular grids the display of view-plane aligned slices has proven to yield both good quality and performance. In this paper we demonstrate how to merge the most important extensions of the original ...
