clean_mesh
Clean mesh by removing unreferenced vertex, and renumber vertex index in face.
Contents
Syntax
[face_new,vertex_new,father] = clean_mesh(face,vertex)
Description
face : double array, nf x 3, connectivity of mesh vertex: double array, nv x 3, vertex of mesh, there may have unreferenced vertex
face_new : double array, nf x 3, connectivity of new mesh after clean vertex_new: double array, nv' x 3, vertex of new mesh. vertex number may less than original mesh father : double array, nv' x 1, father indicates the vertex on original mesh that new vertex comes from.
