Fourier Circles

Epicycle visualization that draws arbitrary SVG paths using Fourier series.

Overview

This project converts any SVG path into rotating circles (epicycles) that reconstruct the shape. Runs natively and in browser via WebAssembly.

Requirements

• C++23 compiler
• CMake 3.25+
• Emscripten 4.0+ (web build only)

Build

Native:

cmake -S . -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build --parallel $(nproc)
./build/FourierCircles

WebAssembly:

emcmake cmake -S . -B build-web -DCMAKE_BUILD_TYPE=Release
cmake --build build-web --parallel $(nproc)
