  • Field Details

    • next

      public Halfedge<X extends Point_> next
      a reference to next half-edge (in ccw direction) in the same incident face

    • opposite

      public Halfedge<X extends Point_> opposite
      a reference to opposite half-edge, lying in the neighboring face

    • vertex

      public Vertex<X extends Point_> vertex
      a reference to target of this half-edge

    • prev

      public Halfedge<X extends Point_> prev
      a reference to previous half-edge (in ccw direction) in the same incident face.
      Remark: storing this reference is redundant, but makes the data structure faster when dealing with polygonal faces.

    • face

      public Face<X extends Point_> face
      a reference to face incident to (containing) this half-edge.
      Remark: this reference can be NULL, when the half-edge is a boundary edge.

    • tag

      public int tag
      an integer that can be used to tag half-edges (useful for dealing with colors, ...)

    • index

      public int index
      an integer that can be used to index half-edges (useful for some applications)
