  //! or  AddVertex(Point,Normal,Texel) methods.
  //! When <hasVColors> is TRUE , you must use one of

  //! or  AddVertex(Point,Normal,Texel) methods.
  //! Warning:
  //! the user is responsible about the orientation of the triangle
  //! depending of the order of the created vertex or edges and this
  //! orientation must be coherent with the vertex normal optionnaly
  //! given at each vertex (See the Orientate() methods).
