#12 Software: A Tcl/Tk tclet to generate wavelet functions


This is to announce the release of my new tclet, a wavelet function
generator. A tclet (pronounced tickle-et) is a Tcl/Tk-based
application that can be run like a Java applet on a web browser. It
requires the Sun Micosystems Tcl/Tk plugin for Netscape and Microsoft
browsers. You can get the plugin at:

Here's what the tclet does:

1. Create orthonormal wavelets via the Pollen parameterization
algorithm, using two angular parameters, alpha and beta.

2. The values of the parameters can be selected by either a) typing
in the parameter values in two entry widgets, b) selecting a point
on a two-dimensional parameter space (on a canvas) with the mouse
pointer or the arrow keys, or c) pressing one of six buttons to
select predefined "interesting" parameter pairs.

3. Display the resulting wavelet coefficients generated by the
Pollen parameterization algorithm.

4. Display the recursively defined wavelet and scaling functions on
another canvas as generated by the "cascade" algorithm. Yes, it will
be faster when the Tcl/Tk plugin has the bytecode compiler in place!

All done in pure Tcl/Tk! Go check it out at:

Don't forget to get and install a copy of the Tcl/Tk plugin first!

Also chek out my home page (listed below) for articles, software, and
pointers on the subject of wavelets.
