I have an XY grid filled with 2d Perlin noise values and I would like to get the countour around a specific threshold as a polyline. The goal is to be able to parametrically offset that contour polyline.
What would be the common way to achieve this in Grasshopper ?
So far I am extracting the points around the cells below a certain value but I’m stuck when it comes to sort them in spatial order to create a polyline.
