Particle-based Visualization of Large Cosmological Datasets

Large quantities of simulated cosmological particle data cause considerable problems when it comes to real-time visualization. In this paper, an efficient approach to solve visualization problems on a single desktop workstation is considered. The approach proposed in this paper consists of two phases: a data preprocessing and its visualization. During the preprocessing, the cosmological data is...

A Scalable Framework for Information Visualization

This paper describes major concepts of a scalable information visualization framework. We assume that the exploration of heterogenous information spaces at arbitrary levels of detail requires a suitable preprocessing of information quantities, the combination of different graphical interfaces and the illustration of the frame of reference of given information sets. The innovative features of ou...

Inverse Visualization In Data Mining

Visualization is used in data mining for visual presentation of already discovered patterns and for discovering new patterns visually. Success in both tasks depends on the ability of presenting abstract patterns as simple visual patterns. Getting simple visualizations for complex abstract patterns is an especially challenging problem. A new approach called inverse visualization (IV) is suggeste...

Database Application in Visualization of Process Data

An information system for visualization of Underground Coal Gasification (UCG) has been developed. The main goal for the system is to provide means for better understanding and control of the process. The system uses mainly data generated during UCG process numerical simulation. Apart from that, the system is capable of storing and visualizing measurement georadar data, gathered during in-situ ...
