A Tool for 3D Visualizing Moving Objects

Visually representing query results and complex data structures in a database system provides a convenient way for users to understand and analyze the data. In this demo, we will present a tool for 3D visualizing moving objects, i.e., spatial objects continuously changing locations over time. Instead of simply reporting numbers and lines, moving objects as well as dynamic attributes are animated and graphically displayed in an unified way. The tool benefits comprehensively understanding the spatio-temporal movement. Furthermore, we introduce how the tool provides powerful visual metaphors to explore the index structure such that one can fast determine whether the structure has a good shape, i.e., well preserving the spatio-temporal proximity. This is not a standalone software but a tool embedded in a database system.
