A part of the user interface of a volume visualization system is described. It provides the opportunity of the real-time interactive definition of viewing parameters for volume rendering. Viewing parameters in this case are the view point and cut planes through the volume data set. It uses an approach for the fast rendering of volume data which tra...
The report contains the user's manual of the visualization system ISVAS (Interactive Software for the Visual Analysis of fracture mechanics), which has been developed for the visualization of the results of three-dimensional finite element analysis. The manual describes how to use ISVAS, the command language, the data formats and a brief installati...
Scientific Visualization gives researchers the opportunity to explore their data with the aid of computer graphics. Volume rendering is the only method, that preserves the entire data set and thus allows a detailed exploration of the volume. The described volume rendering techniques are suitable to be carried out on mid-priced workstations which ar...
In this paper we present the structure of DESIRe, a scalable rendering tool. It is designed as a visualization tool for different applications within integrated working environments and provides a unique interface between users, rendering techniques and hardware platforms. This interface is based on an small set of control items, so-called image qu...
Special rendering methods have been developed in Computer Graphics to make data visible, and manifold data conversion techniques are applied to the original data samples. This paper describes the various steps to be executed in the visualization process of volume data, i.e., to make data values in 3-dimensional space visible. Tools are discussed th...
Volume Data is discrete sampled data in the three-dimensional space. Volume rendering is defined as volume visualization directly from volume primitives and not via surface primitives. Geometric objects are represented as a list of vertices and connecting lines or surface patches. Independend algorithms for rendering the two different categories of...
Visualization systems today have realized many of the concepts required fo visualization. But there are aspects not yet integrated but which will increase significantly system abilities to extract meaning from complex data and unveil hidden coherences in applications. One missing feature is audio, which extends the communication bandwidth between m...
Dieser Bericht beschreibt die "VIS-A-VIS Rendering Schnittstelle" in der Version 2.3. Das "VIS-A-VIS Rendering System" umfasst Module zur Darstellung von Volumendaten, Rasterbildern und polygonalen Objekten. Ausserdem lassen sich die Ergebnisse der einzelnen Darstellungsmodule in einem Mixermodul miteinander kombinieren, was eine Vielzahl neuer Vis...
Volume rendering, i.e. direct rendering of regular volume data and not via surface primitives, is a task of scientific visualization requiring huge computing power. Modern multiprocessor graphic workstations can provide such powerful computing resources, if the rendering algorithm is suitable to be implemented concurrently. The important features o...
Different existing methods for the rendering of different classes of data, i.e. surface and volume data, in one image are described and discussed. Two fundamentaly different strategies for combining the rendering of volume data with the rendering of surface or other geometric primitives have been developed. The first strategy is to convert either v...
