  // Input:
  // V:                 #V by 3 list of mesh vertex positions
  // F:                 #F by 3 list of faces
  // MMatch:            #F by 3 list of per corner integer mismatch
  // is_singularity:    #V by 1 list of booleans that denotes if a vertex is a singularity
  // singularity_index: #V by 1 list of degree of the singularity
  // seams:             #F by 3 list of per corner booleans that denotes if an edge is a seam or not
  //
  // TODO: remove is_singularity, it is redundant
  //       make the name of the variables consistent in the cpp
