Let's suppose we have 5 (x,y) points which makes a closed loop or a polygon. How can I interpolate or upsample some points so that the polygon will have a more round-ish look instead of sharp linear lines between two points? E.g. see the image. What I have is on the left and what I want is on the right.

A simple MATLAB code is as follows:

xv = [0 2 3 2.5 1 0];
yv = [1 0 2 3.5 3.5 1];
plot(xv, yv)
xlim([-1 4])
ylim([-2 5])

  • You could [have a look at this](https://gis.stackexchange.com/questions/24827/smoothing-polygons-in-contour-map) and apply similar ideas to your polygon. – wsdookadr Dec 18 '20 at 19:11
  • You should add a MatLab tag, and also mention it in the subject line. – MarkHu Dec 18 '20 at 20:03
