R6 Based Utilities for 3D Meshes using 'CGAL'
Provides some utilities for 3D meshes: clipping of a mesh to the volume bounded by another mesh, decomposition into convex parts, distance between a mesh and a point, Hausdorff distance between two meshes, triangulation, geodesic distance, Boolean operations (intersection, union, difference), Minkowski sum, subdivision algorithms, random sampling on a mesh, volume, area, and centroid. Also provides two algorithms for surface reconstruction from a cloud of points. Meshes are represented by R6 classes. All algorithms are performed by the 'C++' library 'CGAL' (< https://www.cgal.org/>).
