Geometric Utilities

In the course of many geometric visualization projects, Geometry Center staff and visitors have created a number of very useful utility programs. Glance over the descriptions below and keep them at the back of your mind, so you needn't waste time inventing a wheel, when you can get a roller bearing off the shelf!

All packages can be downloaded directly from the Geometry Center Software archive. Program name links lead to their respective man pages.

epsilon -- Epsilon is a data filter for squashing floating point round off errors. The compiled version is not installed, so get the source.
Geometric Utilities -- This is a collection routines for manipulating polygons and arcs.
- poly2tri breaks arbitrary polygons into triangles .
- poly2area computing polygon areas.
- poly2xy places polygons in 3-space in the XY plane.
- arc2list converts arcs into polylines.
omni_make and omni_interp -- These utilities are designed to manipulate and interpolate arbitrary data sets. The user supplies C routines to operate on data in a particular format. The executables are installed, but there are no man pages. However, there is good documentation, including examples, in the standard distribution in the Center software archive.
