Geomview is an interactive 3D viewing program for Linux and other flavors of unix. It lets you view and manipulate 3D objects: you use the mouse to rotate, translate, zoom in and out, etc. It can be used as a standalone viewer for static objects or as a display engine for other programs which produce dynamically changing geometry. It can display objects in hyperbolic space or spherical space as well as Euclidean space. Geomview was written at the Geometry Center at the University of Minnesota between 1992 and 1996. Although the Geometry Center closed in 1998, Geomview is still used by many people around the world.
