Fig. 9From: Alpha shapes: determining 3D shape complexity across morphologically diverse structures‘Coastline paradox’ example. 2D point clouds of Great Britain increase in density from a-f. As point cloud density increases, refinement coefficient k must decrease in order to resolve fine-scale features and maintain an equivalent alpha-shape area.
