// .NAME vtkHexagonalPrism - a 3D cell that represents a prism with
// hexagonal base
// .SECTION Description
// vtkHexagonalPrism is a concrete implementation of vtkCell to represent a
// linear 3D prism with hexagonal base. Such prism is defined by the twelve points
// (0-12) where (0,1,2,3,4,5) is the base of the prism which, using the right
// hand rule, forms a hexagon whose normal points is in the direction of the
// opposite face (6,7,8,9,10,11).
// .SECTION Thanks
// Thanks to Philippe Guerville who developed this class.
// Thanks to Charles Pignerol (CEA-DAM, France) who ported this class under
// VTK 4.
// Thanks to Jean Favre (CSCS, Switzerland) who contributed to integrate this
// class in VTK.
// Please address all comments to Jean Favre (jfavre at cscs.ch).
