Fourier Series Animation

This repo holds the code for my medium article on animating Fourier series.

To install the requirements:

pip install -r requirements.txt

The directory structure for the repo: ⤵⤵

├── arrow_animation.py ➡ arrow animation generation script.
├── evolution_demo.py ➡ evolution animation generation script.
├── core ➡ core scripts and modules.
│ ├── fourier_drawer.py ➡ for drawing Fourier coefficients using opencv
│ ├── fourier_numerical_approximator.py ➡ finding coefficients.
│ └── generate_points.py ➡ generate the PTS files.
├── data ➡ SVG files + PTS files, example fourier.svg.
├── demos ➡ demo GIFs for repo preview.
└── example
│ ├── bezier.py ➡ making random smooth curves.
│ ├── generate_joseph_fourier_portrait.py ➡ generate the PTS file for fourier.svg

How to use:

1. To generate an arrow animation

   python arrow_animation.py
   

   This will generate the arrow animation for the points fed to FOUR.animate(points,...) method, check the examples in the script
2. To generate an arrow animation

   evolution_demo.py
   

   This will generate evolution animation for the points fed to FOUR.evolve(points,...) method, check the examples in the script
