Hyperbolic Tessellations

Details about the applet

I originally wrote this program in the programming language Pasacl back in April, 1987. It produced hyperbolic tessellations in a Poincaré disk for display on a Tektronix terminal. I finally got around to translating it into Java for an applet in December, 2002.

Much of the program is the same. The mathematics is the same, and the overall algorithm hasn't changed. But the interface with the user is quite different. Also, Java is an object-oriented language while Pascal is not, so the structure of the program looks quite different in places.

Applet tags

There are a number of parameter tags for the applet. Many of these appear as buttons as well, but not all of them.

Components of the applet

The source code for each class of the applet is in a file *.java, and its compiled code is in the corresponding *.class file.
