falkourier
falkourier is a Python library that draws images, sketches, and curves using Fourier series epicycles (rotating circles). It converts any 2D outline into mathematical harmonic frequencies and animates the drawing process.
Created by @falkomeai.
- Live Web Studio: https://fourier-studio.streamlit.app
- GitHub Repository: falkomeAI/Fourier-Epicycle-Drawing-Studio
Installation
pip install falkourier
Quick Start
1. Web Studio UI
The easiest way to use it is through the interactive web interface:
falkourier-studio
This launches a local web app in your browser where you can upload an image, tune the number of harmonics, preview the epicycles live, and export MP4 videos.
2. Command Line
You can also generate videos directly from your terminal:
# Render a video from an image
falkourier --image portrait.jpg --n 500 --save output.mp4
# Render vertical 9:16 format (for Instagram Reels or TikTok)
falkourier --shape hummingbird --n 300 --format reels --save reel.mp4
# Render from built-in curves
falkourier --shape heart --n 200 --save heart.mp4
3. Python Code
import falkourier as fk
# 1. Use a built-in curve or extract from an image
path = fk.SHAPES["hummingbird"]()
# path = fk.extract_boundary_contour_path("portrait.jpg", target_points=2048)
# 2. Fit Fourier series
fit = fk.fit_fourier(path[:, 0], path[:, 1], n_harmonics=500)
print(f"X harmonics: {len(fit['x_coeffs']['an'])}")
print(f"Y harmonics: {len(fit['y_coeffs']['cn'])}")
Built-in Shapes
You can try out any of the built-in mathematical curves:
hummingbird, heart, star, butterfly, infinity, spiral, rose.
import falkourier as fk
curve = fk.SHAPES["butterfly"]()
