Method GetNumberOfApproximatingWedges

Common/DataModel/vtkHigherOrderWedge.cxx:923–942

\brief Return the number of linear wedges we use to approximate this nonlinear wedge. * * Note that \a order must be a pointer to an array of **four** integers. * The first 3 values specify the order along the r, s, and t parametric axes * of the wedge, respectively. * The first 2 values must be identical. * * The final (fourth) value must be the number of points in the wedge's connectivity

 * triangles (a serendipity element).
