Functions for filling the holes in a mesh.
Global Vorpaline namespace.
Definition: basic.h:55
void orient_normals(Mesh &M)
Orients the normals in such a way that each connected component has a positive signed volume.
void remove_small_connected_components(Mesh &M, double min_component_area, index_t min_component_facets=0.0)
Removes the connected components that have an area smaller than a given threshold.
void expand_border(Mesh &M, double epsilon)
Enlarges a surface by moving the vertices on the border.
void remove_degree2_vertices(Mesh &M)
Removes the degree 2 vertices in a surface mesh.
