Name the two main approaches to extract the surface of a 3D object from a point cloud!
Contour Tessellation
Create a Delaunay tetrahedralization of the point cloud. Try to keep only those faces which correspond to the object surface (Voronoi Filtering)
Volumetric Approaches
Take points as samples of a volumetric representation of the mesh. Reconstruct the density function (weighted averaging, Poisson reconstruction) and extract an isosurface (Marching Cubes).
