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...
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...

The preprocessing of 3-dimensional (3D) MRI data constitutes a bottleneck in the process of visualizing the brain surface with volume rendering. As a fast way to achieve this preprocessing, the authors propose a simple pipeline based on an algorithm of seedgrowing type, for approximate segmentation of the intradural space in T1-weighted 3D MRI data...
