+Geomview is the product of an effort at the Geometry Center at the
+University of Minnesota to provide interactive geometry software which
+is particularly appropriate for mathematics research and education.
+In particular, geomview can display things in hyperbolic and spherical
+space as well as Euclidean space.
+
+Geomview allows multiple independently controllable objects and
+cameras. It provides interactive control for motion, appearances
+(including lighting, shading, and materials), picking on an
+object, edge or vertex level, snapshots in SGI image file or
+Renderman RIB format, and adding or deleting objects is provided
+through direct mouse manipulation, control panels, and keyboard
+shortcuts. External programs can drive desired aspects of the
+viewer (such as continually loading changing geometry or
+controlling the motion of certain objects) while allowing
+interactive control of everything else.
+
+Geomview supports the following simple data types: polyhedra with
+shared vertices (.off), quadrilaterals, rectangular meshes,
+vectors, and Bezier surface patches of arbitrary degree including
+rational patches. Object hierarchies can be constructed with
+lists of objects and instances of object(s) transformed by one or
+many 4x4 matrices. Arbitrary portions of changing hierarchies
+may be transmitted by creating named references.
