Hilbert curve approximation using epicycles/complex Fourier series

Показать описание

The video linked above also does a great job at explaining the mathematics required into make this video.

In the first section of the video the red lines/circles represent all counter-clockwise rotating epicycles (or exponents of the Fourier series with positive integers) and the green lines/circles represent all clockwise rotating epicycles (or exponents of the Fourier series with negative integers).

In the second section of the video the curves of an increasing order Fourier series are interpolated. This order will jump frequently because due to the symmetry of the Hilbert curve all the even integer Fourier coefficients are zero, so are skipped in the interpolation.

Thanks, this is really nice to see. I'd like to see the Fourier coefficients too

Nice anim.❤️❤️❤️
But, Can you please tell, how do you get or extracted the data of the shapes?

Which software you are using to make this animation sir?

The high order Fourier transformation of this curve consists of scaled down low order Fourier transforms of this curve.
Is that visible in the equation of the function?
