 Evolver 1.99

The Surface Evolver is an interactive program for the study of surfaces
shaped by surface tension. Given an initial surface, the Evolver can
evolve it toward minimal energy. The energy can be surface tension,
gravitational energy, squared mean curvature, or userdefined surface
integrals. The Evolver can handle arbitrary topology (as seen in real
soap bubble clusters), volume constraints, boundary constraints,
boundary contact angles, prescribed mean curvature, crystalline
integrands, gravity, and constraints expressed as surface integrals.
The surface can be in an arbitrary dimensional Riemannian space with a
metric, and the space can be a quotient space under a group action. The
Evolver was written for one and two dimensional surfaces, but it can do
higher dimensional surfaces with some restrictions on the features
available.

 Geomview 1.5

Geomview is an interactive program for viewing and manipulating
geometric objects. It can be used as a standalone viewer for static
objects or as a display engine for other programs which produce
dynamically changing geometry.
