Abstract

Large numerical calculations are made to get a prediction what damage a possible flood would cause. These results of the simulation are used to prevent further flood catastrophes. The more realistic a visualization of these calculations is the more precaution will be taken by the local authority and the citizens. This paper describes a tool and techniques to get a realistic looking, three-dimensional, easy to use, realtime visualization despite of the huge amount of data given from the flood simulation process.

The tool

The animations were generated with the programm "HW3D" that I developed during my research. The tool can visualize terrain surfaces with a high resolution in real-time. It also handles large textures. In order to get a realistic visualization, buildings were reconstructed using the original floor plans of cities. Other GIS data like topography points can also be visualized by the tool.
