L.E.G.O. − An interactive graphics system for teaching geometry and computer graphics Norma Fuller and Przemyslaw Prusinkiewicz Abstract L.E.G.O. is an interactive graphics system for creating, viewing and manipulating two−dimensional geometric figures and three−dimensional objects. The fundamental operations of the L.E.G.O. language form an electronic metaphor of geometric constructions with a straightedge and compass. This is consistent with the primary application of L.E.G.O., i.
