ftp://ftp.geom.umn.edu/pub/software/evolver/evolver.tar.Z Surface Evolver <author> <version> <abstract> 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 user-defined 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. <description><url>http://www.geom.umn.edu/docs/software/viz/evolver/evolver.html</url> <reference><url></url> <contact>brakke@geom.umn.edu <keywords>computational geometry <category>numerical-compgeom <publication-date> <environment>NeXT, Mac, Intel 386/486 <method> <application> <comments> The Evolver is written in portable C and has been run on several systems: Sun, Iris, NeXT, Xenix, Cray, MS-DOS, and HP 98731. </urc>
