Fourier Epicycles Simulator

This web application allows you to draw any single stroke drawing and observe how it can be drawn using revolving circles.

You can control the accuracy of the epicycles (correlates linearily to the amount of circles, accuracy N results in 2N + 1 circles), as well as the framerate of the simulation.

For development

This web app uses Svelte with Typescript and Vite, as well as Rust WebAssembly for more intensive computations. Drawing is done through p5.js.

To-do

• Support for importing SVG files could be interesting, but in the case that the file has multiple strokes, there's ambiguity on which stroke to pick while keeping the system intuitive
• Exporting coefficients, as .TXT or maybe even .CSV or .JSON files
