JiScript - dynamic mathematical illustrations
JiScript is a package that enables programmers to create mathematical illustrations in Java by writing Python code. The guiding principle is that JiScript should make the production of high-quality Java illustrations, including animations and other interactivity, as effortless as possible.
Of course, one could program directly in Java. JiScript offers at least two advantages, however. First, the graphics commands in JiScript are the same as those in Bill Casselman's PiScript, a Python package that produces PostScript figures. It is therefore possible to produce either PostScript or Java graphics using the same set of commands.
Second, because JiScript programs are written in Python, they are typically much shorter and developed much more efficiently than Java programs. JiScript uses Jython, a Python interpreter written in Java, to produce Java bytecode. This means that JiScript can produce Java applets, which may be widely distributed over the Internet.
Note: This package was originally called
JyScript. The
name was changed to
JiScript to reflect its close connection
with
PiScript.

Installation instructions
jiscript.zip into a directory
(folder).
python.path
variable points to that directory.
For example, on my linux machine, JiScript is
installed in
/home/david/jiscript
and Jython is installed in /home/david/jython2.2.1.
/home/david/jython2.2.1/registry,
and I edited one line
to read
python.path = /home/david/.
jython and jythonc
executables in your path. For example, in a bash shell, type
something like
export PATH=/home/david/jython2.2.1:$PATH
Running a Jython file
App.jy, it may be run from the command line with
jython App.jy
