Geometric Querying for Dynamic Exploration of Multidimensional Data

This paper describes a geometric query model for dynamic exploring multidimensional data. An application of the model for solving the problem of materials selection in product design is discussed. Data from database are interpreted geometrically as multidimensional points. A query window is a query solid of any shape specified by its location. The queries are formulated with geometric objects and operations over them. The geometric objects and operations are described with implicit functions. The process of query specification is visualized. The user poses the queries through graphics interface accessing dynamically multidimensional points, geometric primitives and applying geometric operations over them.
