[Feature Request] Option for closed mode

[mazznoer]

New option for closed/ loop mode, where start point and end point supposed to be connected.

Sorry for my broken english.

@mazznoer Hey :) You could prepare your array by duplicating your starting point and append it to the end of the list, before calling the fit function. That should give you a closed polyline.

It would be closed, but the curves wouldn't match. Getting the curves to match would be a bit more difficult.

[mazznoer]

@Yay295 Exactly

Here is another sample points and its output.

let points = [[172,100],[166,114],[160,127],[156,141],[149,155],[128,149],[121,164],[107,163],[93,163],[82,154],[65,160],[52,154],[44,141],[35,129],[26,116],[37,100],[44,88],[28,68],[41,57],[48,42],[63,36],[77,28],[92,25],[108,28],[121,37],[130,48],[148,46],[156,59],[161,73],[163,87],[172,100]];

fitCurve(points, 30);

Everything is smooth, except where the start and end point meet (green circle).

I'd love to see this feature implemented.
