Spherical perspective in design education

Abstract

The spherical perspective has not yet been widely introduced into design education. Its ability to serve as a meta-class model of vanishing point perspective systems, giving a teacher the opportunity to present approximations of the straight linear perspective models (with one, two or three vanishing points) all in one system, is presented in this article. The mathematical basis for a spherical grid as a curvilinear approximation to one-eyed human vision and a didactic approach for its integration into design oriented perspective freehand drawing are also discussed.
