Winding numbers using a Cauchy integral, with WebGL
Winding numbers using a Cauchy integral, with WebGL This is what the winding number n(γ,a) of curve γ around point a, expressed as special case of Cauchy’s integral formula looks like on potentially nonclosed loops, with complex numbers mapped to a hueluminance space.
$$ n(\gamma ,a) = \frac{1}{2 \pi i}\int_{\gamma}^{}\frac{1}{za}dz $$
