Description

There are various methods in the literature to compute the "concave" hull of a 2D point set:

https://www.researchgate.net/publication/312373158_A_Concave_Hull_Based_Algorithm_for_Object_Shape_Reconstruction

We can use ConcaveHull.jl as a test bed, it implements the method that is based on the modification of Jarvis march that we already have implemented with k-nearest neighbors.

Contributor guide

Research direction
Study the Jarvis march algorithm implementation in Meshes.jl and modify it to use k nearest neighbors to compute concave hull, using ConcaveHull.jl as a reference.
