Mesh Watertightness

About

The optimized meshes are guaranteed to have good topology and convenient polygonization, nevertheless, their watertightness is not guaranteed; the optimizer might introduce self-intersecting triangles depending on surface complexity and roughness. Watertightness has been addressed by extending an existing solution based on \textsc{\href{https://github.com/MarcoAttene/MeshFix-V2.1}{MeshFix}}~\autocite{attene2010lightweight} that uses a heuristic iterative approach that strives to reconstruct a single compact manifold with neither degeneracies nor self-intersections from a low quality self-intersecting input.
