This is a fast implementation of concave hull using a k-nearest neighbour approach.
Concave Hull on LiDAR Point Cloud Data with over 1M points. The calculation took 2.88 seconds to run.
The current implementation is based on the paper
Moreira, A., & Santos, M. Y. (2007). Concave hull: A k-nearest neighbours approach for the computation of the region occupied by a set of points.
The algorithm has a parameter
