About

My main interest has been visual results, and that tends to be a primary criterion for deciding whether a program is working correctly or not. While I would like the programs to work as well as possible they are not meant to be considered as producing careful numerical solutions, even though the coordinate data for the models is usually accurate to high precision.

I have made the programs available in the hope that they will be of interest to other people, maybe useful, but mostly that they will be fun to play with.

The Antiprism List is a general and informal list for discussing geometry. There are lots of posts about the Antiprism programs. Please, use this group to ask for support, give feedback, or generally discuss the Antiprism programs. Posts about other programs or projects are very welcome, as are posts just to share your interests in geometry.
