4434Fourier: Making Waves
http://www.merlot.org/merlot/viewMaterial.htm?id=85116
An interactive simulation designed to help students understand fourier series. Includes a discrete-only module and a module that illustrates the transition from discrete to continuous transforms. A wave game module in which students try to match a given waveform is also included.Fourier Synthesis (Math)

A collection of links to sites that discuss famous curves, as well as a wealth of other mathematical topics. Most are a mix of math, history, and computer graphics. Source code is usually available.Fourier Transform
http://www.merlot.org/merlot/viewMaterial.htm?id=91098
This is a simple demonstration of the Fourier transform (diffraction pattern) of a point set. This program produces black/white or color PostScript output. The source code is provided with the package. This DEMO program is similar to the one that Marjorie Senechal shows in her book Quasicrystals and Geometry. It is possible to give scale factors for the intensity and for the input data to produce different graphics output. You may also choose between kinematical or dynamical intensity distribution. For input you only need an input file with the x- and y-coordinates of a point set.JFourier1

From the directions: "Click new motif to start drawing a new point set. Then select one of the colors, which correspond to different scattering strengths (1-9) and click on the left canvas to position your points. Then click Fourier transform to calculate the discrete Fourier transform of that point set."JFourier2

This applet calculates Fourier transforms (FT) of a given pointset. The pointset is generated by the plane space groups (see Project 22). You may transform all points or only one unit cell. Similar to JFourier3 by the same author, except for periodic (not quasiperiodic) point sets.JFourier3
