Visualization Of Seismic Wave Data By Volume Rendering And Its Application To An Interactive Query Tool

We propose the Queryball model, which is a new style interaction model for a 3D visualization system. Queryball, which is a translucent ball, has search conditions, and two types of display methods. By locating a Queryball on the region of interest, users can observe just the objects they are interested in with emphasizing them and having other objects disappear. Users can change the region of interest by changing the area specification of the Queryball interactively. Although Queryball is useful for interactive analyze of various kinds of data, we need to consider and provide various usage of Queryball. In this paper, as the first step for providing such examples, we visualize seismic wave data and the underground structure of the earth. We apply some Queryballs to the results which are obtained by a volume rendering technique and an appropriate transfer function by examining the data distribution.
