Spectrum Buildup

Animation demonstrating how adding more Fourier coefficients sharpens shape approximation.

Remarks

  • The animation progresses through stages (e.g. 1, 2, 3, 5, 8, 13, 20, 40 coefficients), each drawing one full revolution. Early stages produce rough shapes; later stages reveal the full shape.
