What is a 'good' visualization, one which leads to desired insights? How can we evaluate the quality of a scientific visualization or compare two visualizations (or visualization systems) to each other? In the following, the importance of considering the 'visualization context' is stressed. It consists of the prior knowledge of the user; the aims o...
The concept of CASUS Base is sketched: a universal animation elements library allowing everyone to create animations for everything. First results and examples made in an industrial context are shown.
To ensure a high level of human health protection the huge data sets gathered by the physicians of the health service have to be analyzed in an efficient way. In this paper we discuss the visualization of human health data with geographical and temporal dependence and describe the prototype of the visualization system MedVis which has been develope...
Scientific visualization systems normally use keyboard or mouse as input devices and desktop screens or printers/plotters for output. virtual Environment systems, on the other hand, use devices like glove or head mounted display and a number of software techniques in order to achive realistic, immersive real-time graphics. This paper discusses the ...
This paper discusses a general scheme for determining the quality of scientific visualization systems. It presents psychological tests which have been performed in order to find quantitative relaationships for this scheme, and discusses why simple numerical relationships may be hard to find. Our work is motivated by research into interactive and im...
This paper presents an overview of Virtual Relaity (VR) system technology and its application within the Fraunhofer Demonstration Centre for VR at IGD in Darmstadt. First we discuss the essential dimension in virtual environments (VE), namely the simulation, the interaction and the presentation dimension. A brief reflection on VR devices and system...
This paper presents an overview of Virtual Reality system technology and its application within the Fraunhofer Demonstration Centre for VR. Various preprocessing and editing tools are introduced and their benefit for the realization of efficient and high-quality virtual worlds are highlighted. A broad range of applications demonstrate the usabiliti...
At the Fraunhofer Institute for Computer Graphics an interactive system for the visualization of environmental data called VISMAR, has been developed. This system allows both the interactive design and production of maps of any geographical region and the visualization of marine environmental data in that geographical context using different kinds ...
Since its beginning in the early thirties, animation has been an application in its own right. Nowadays animation provides a set of tools, or is the basic technology for several other applications of computer graphics and related areas. These include: Scientific Visualization: visual patterns showing relationships between data; as much of the data ...
Scientific Visualization is regarded as the enabling technology that demands integration of applications with Computer Graphics and Computer Vision. Scientific Visualization comprises methods to generate and display graphical representations of complex data sets which are from simulations or scientific experiments. A visualization system for scient...
