* @class vtkBezierTetra
|
|
* @brief A 3D cell that represents an arbitrary order Bezier tetrahedron
|
|
*
|
|
* vtkBezierTetra is a concrete implementation of vtkCell to represent a
|
|
* 3D tetrahedron using Bezier shape functions of user specified order.
|
|
*
|
|
* The number of points in a Bezier cell determines the order over which they
|
|
* are iterated relative to the parametric coordinate system of the cell. The
|
|
* first points that are reported are vertices. They appear in the same order in
|
|
* which they would appear in linear cells. Mid-edge points are reported next.
|
|
* They are reported in sequence. For two- and three-dimensional (3D) cells, the
|
|
* following set of points to be reported are face points. Finally, 3D cells
|
|
* report points interior to their volume.
