The i3d has a port of the common library from this code using a class structure in version 0.98.0. The programs are considered stable except where the documentation says either 'Ignore this program' or 'Code is unstable'. If you find bugs, please tell me . To configure for your operating system, edit the file Configuration before building the software. TeX documentation is in the tarball, and pre-0.98.4 documentation is on the web .
Demonstrations are in the live documentation.
I will add more applications to the suite. Please send me suggestions. I am thinking of implementing a bookkeeping system, go, and reversi. The last release here may be on the testbed, and so not linked below. Fixed outputting the image directory.
