- Lénárt_sphere abstract "A Lénárt sphere is a teaching and educational research model for non-Euclidean geometry, especially spherical geometry, spherical trigonometry, and projective geometry. The Lénárt sphere has been called a "spherical blackboard" for use in visualizing polygons (especially triangles) on the sphere and the relationships between the sides and the angles. The sphere is used like visualization software programs such as The Geometer's Sketchpad, GeoGebra and Spherical Easel (see External Links for Spherical Easel information, and visit List of interactive geometry software for Non Euclid, and many other interactive Projective geometry apps and programs). Example educational applications of the Lénárt sphere include Geodesy, GIS, astronomy, geometry, ray tracing (graphics), perspective (graphical), trigonometry and celestial navigation.".
