Spirograph using the Fourier Series

Translates any SVG image into an approximation of it using the Fourier Series and renders it with a spirograph. Inspired by 3Blue1Brown https://www.youtube.com/watch?v=r6sGWTCMz2k

Getting started

Dependencies: sfml, imgui, imgui-sfml, nanosvg, noc (file dialog) Optional: cotire (speedup builds), jet-live (hot reload)

Linux

sudo pacman -S sfml

git clone github.com/erikgoe/fourier-spirograph

mkdir dep && cd dep
git clone https://github.com/ocornut/imgui
git clone https://github.com/eliasdaler/imgui-sfml
git clone https://github.com/memononen/nanosvg
git clone https://github.com/guillaumechereau/noc
cat imgui-sfml/imconfig-SFML.h >> imgui/imconfig.h

# Optional
git clone https://github.com/sakra/cotire
git clone https://github.com/ddovod/jet-live

mkdir build && cd build
cmake ..
make

Windows

Download sfml (https://www.sfml-dev.org/download.php) and extract it somewhere.

git clone github.com/erikgoe/fourier-spirograph

mkdir dep && cd dep
git clone https://github.com/ocornut/imgui
git clone https://github.com/eliasdaler/imgui-sfml
git clone https://github.com/memononen/nanosvg
git clone https://github.com/guillaumechereau/noc
copy /b imgui\imconfig.h + imgui-sfml\imconfig-SFML.h imgui\imconfig.h

# Optional
git clone https://github.com/sakra/cotire
git clone https://github.com/ddovod/jet-live

mkdir build && cd build
cmake .. -DSFML_PATH=C:/src/sfml/SFML-2.5.1
msbuild ALL_BUILD.vcxproj

SFML_PATH should be the path to the directory where you extracted sfml into.

Alternatively you can build the .sln in Visual Studio.
