Software packages:

GABLE, a Matlab tutorial introduction to Geometric Algebra.
ccycloid, a Windows program (also available for Linux, if desired) to plot (PostScript, PDF, and DXF) curtate cycloids.
catenary, a Windows program (also available for Linux, if desired) to plot (PostScript, PDF, and DXF) catenary curves.
Coordinate Free Geometry Software
Blossoming Software , a C++ library supporting blossoms. You need some of the gp software written by Richard Bartels (available at the blossom link), and some of STL.
Comp.tar.gz is a C++ implementation of the composition algorithm(s) described in Functional Composition via Blossoming (with T. DeRose, R. Goldman, and H. Hagen), ACM Transactions on Graphics, Vol. 12, No. 2, April 1993.
SF.tar.Z is a C implementation (using gcc, tested on Suns) of the Surface Fitting Pipeline described A Testbed for the Comparison of Parametric Surface Methods (with M. Lounsbery, C. Loop, D. Meyers, J. Painter, T. DeRose and K. Sloan), in the proceedings of SPIE/SPSE Symposium on Electronic Imaging Science and Technology, Santa Clara, CA, February, 1990.
An older version of the software, SurfaceFitting.tar.gz, is still available.

The following is a list of scripts (shell, perl, awk, etc) that I have found useful. Some I wrote, some I got from other sources. You will probably need to change the first line of the script (the one that says where to find perl, etc).

The ones I wrote aren't very polished; I wrote them to perform specfic tasks I wanted computed. bibenter and gapm are the exception to this; they're reasonably polished (gapm is simple enough that there's not much to polish).

Scripts I wrote:

gapm (Graphical Advanced Power Management) is a Tcl/Tk script for monitoring the power on your laptop computer.
bibenter (version 3.0) is a Tcl/Tk script for entering and editing BibTeX files.
pssched is a Perl script for creating a pretty schedule. It reads a human readable format, and translates it to PostScript. The PostScript schedule appearing in my homepage is formated from ASCII using pssched.
When printing ASCII files, I was tired of page breaks being inserted in the middle of paragraphs, so I wrote lbreak, a simple Perl script to insert page breaks into an ASCII file in between paragraphs.

Scripts I cowrote:

pscal is a C shell script for creating an PostScript calendar. The original was written by Patrickwood (see the copyright notice contained inside). There are newer versions of this program, but it was converted to a Bourne shell script, so I've stuck with this version.
hpscal is a Perl script for creating a 17 week calendar. All I did was modify pscal.
psproof is a Perl script that takes a conforming PostScript file and puts multiple pages on one page. There are millions of these programs floating around, so I may as well add the one that I co-wrote with Hugues Hoppe.

Scripts others wrote:

bib2dvi Written by Dag Asheim. This C shell script takes a BiBTeX file and produces a .dvi file.
cal3 Written by Curt McDowell. Prints out 3 consecutive months of the calendar.

Up one level.
