Turn your 2D curves into animated Fourier drawings with ease.

Fourier Epicycles is a Blender add-on that converts hand-drawn or imported 2D curves into dynamic epicycle animations using the Fast Fourier Transform (FFT). It analyzes the shape of a curve, breaks it into circular motion components, and rebuilds it as a chain of rotating circles, arms, and a traced motion path.

This gives artists and motion designers a fast way to create stylized line art, logo reveals, looping motion graphics, scientific visualizations, and expressive animation from simple 2D paths. Instead of manually keyframing complex motion, the add-on automatically generates a visually rich animation based on the geometry of the source curve.

What makes it useful:

• Works with selected curves or an entire source collection
• Supports multiple splines and chain generation from a single path
• Lets you control sample resolution, circle count, frame count, and trace behavior
• Creates a clean output collection with generated rings, arms, tip, and trace
• Includes camera, background, and render-friendly controls for quick production use

Whether you are creating a smooth looping animation, a decorative infographic effect, or a visually interesting tracing study, Fourier Epicycles helps you turn a flat curve into a powerful motion design element with just a few clicks.

For designers and creators who want to explore the beauty of mathematical motion in Blender, this add-on offers a simple and expressive workflow with professional-looking results.
