Interactive Stereoscopy System Showing the Principle of Stereographic Projection

Abstract

Stereographic projection is a useful tool to represent unit vectors in 3-D space. The principle of the projection based on 3-D geometry is hardly understood by students, because it is usually explained using figures drawn on 2-D plane. An interactive system of stereoscopy has been developed to display the principle with a personal computer. Using this system, students are expected to easily understand the stereographic projection.
