Gawain Version 4

This is version 4 of the Gawain algorithm animation system. You will need:
  1. Java 1.1: this is available on Netscape 4 and Internet Explorer 4.
  2. A fast machine. Gawain uses a lot of resources.
  3. Patience: Gawain is large, so downloading the code may take a while.

Gawain runs in two modes:

  1. In standalone mode, Gawain can be used to developing animations which can later be inserted in web pages or made into videos.
  2. In applet mode, Gawain can illustrate web pages.

Applet mode

Here are examples of Gawain in applet mode:

Standalone mode

Gawain can run as an application within the browser. That's what's happening in this page. But due to browser security restrictions, you can only access files and execute programs on the web server, which slows things down (and is a bit awkward).

It is easier to run Gawain as a Java application. You will need all the source files and the data directories, which are available as a gzip'ed tar archive and in zip format. I'm still working on documentation, but there should be enough reading material to get you started.

Further Reading

If you want to learn more about animating geometric algorithms, David Dobkin and I have prepared an introduction, which will appear in "A Handbook of Computational Geometry".
