|
* @class vtkHexagonalPrism
|
|
* @brief a 3D cell that represents a prism with
|
|
* hexagonal base
|
|
*
|
|
* 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).
|
|
*
|
|
* @par 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).
