侘び寂びフーリエ変換

This is an app that converts line drawings into a form that can be output as pure mathematical formulas, Javascript, or GeoGebra.

I happened to see the concept of Fourier series transformation on YouTube Shorts and impulsively created this. There was one problem that kept causing short circuits that I couldn't eliminate, but I gave up on that in order to make it work as a web app.

Since it comes with epicycle animation, you can kill some time just watching it. It can convert even drawings made with the Paint tool that comes standard on Windows to a certain degree, so please try playing with it.
