  • Field Details

    • neighbors

      protected ObjectList<GRSVertex> neighbors
      Cyclic neighborhood of this vertex. This contains all neighboring vertices (those that are connected with this vertex by an edge of the polygon mesh). The neighbors are sorted in a cyclic way, namely in counter-clockwise order when seen from above of the mesh.

    • u

      protected float u
      u coordinate of vertex

    • v

      protected float v
      v coordinate of vertex
