About

The various programs included in Antiprism were developed for personal use. I wrote them as an aid to understanding and exploring ideas in geometry.

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 site and project are developed and maintained by Adrian Rossiter. You can contact me by email at adrian@antiprism.com.

The Antiprism List is a general and informal group for discussing geometry. There are lots of posts about the Antiprism programs. Please use this group to ask for support, give feedback, or discuss the Antiprism programs.
