Python implementation of "Elliptic Fourier Features of a Closed Contour"

pyffs

Fast Fourier Series library.

fourier-drawing

Fourier series visualizer - real-time epicycle simulation reconstructing arbitrary drawings via DFT coefficients

foldoptlib

Fold geometry optimisation pluging for LoopStructural & Map2Loop

f2depine
