Geological, geochemical and geophysical data are always multi-dimensional. In conventional methods, however, a relation between only two properties are displayed on a 2-dimensional sheet. On the contrary, a computer system of interactive stereoscopy can display a relation among three parameters at the same time. The system consists of four subsystems of crystal structures, geological structures, geochemical data, and education of the stereographic projection. All subsystems are called from the menu of the system, and almost independent each other. In order to observe a 3-dimensional shape of an object, all subsystems have functions to change an optical angle, to turn a figure around three axes, to enlarge or reduce a figure, to shift a figure, and to change a legend. Using this system, students learn easily crystal structures, and principle of the stereographic projection. Exploration engineers understand a 3-dimensional structure of geology. A geochemical relation among three components are represented in a tetrahedron or a cube. Flow vectors and stress tensors are also displayedin a 3-dimensional space. It is expected, therefore, that the interactive stereoscopy should give many valuable suggestions in the geological, geochemical and geophysical discussions, to the exploration of mineral and energy resources, and to other scientific and technological fields.
