Geomview is interactive geometry software which is particularly appropriate for mathematics research and education. It can be used as a standalone viewer for static objects, or as a display engine for other programs which produce dynamically changing geometry.
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.
The software was originally written by staff members of the Geometry Centre at the University of Minnesota. It is mature software with development commencing in 1991.
- Supports simple data types:
- Polyhedra with shared vertices (.off).
- Rectangular meshes.
- 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 4×4 matrices.
- Can be used as a Mathematica graphics output device.
- Wide selection of example objects.
