* @class vtkBezierWedge
|
||
|
|
* @brief A 3D cell that represents an arbitrary order Bezier wedge
|
||
|
|
*
|
||
|
|
* vtkBezierWedge is a concrete implementation of vtkCell to represent a
|
||
|
|
* 3D wedge using Bezier shape functions of user specified order.
|
||
|
|
* A wedge consists of two triangular and three quadrilateral faces.
|
||
|
|
* The first six points of the wedge (0-5) are the "corner" points
|
||
|
|
* where the first three points are the base of the wedge. This wedge
|
||
|
|
* point ordering is opposite the vtkWedge ordering though in that
|
||
|
|
* the base of the wedge defined by the first three points (0,1,2) form
|
||
|
|
* a triangle whose normal points inward (toward the triangular face (3,4,5)).
|
||
|
|
* While this is opposite the vtkWedge convention it is consistent with
|
||
|
|
* every other cell type in VTK. The first 2 parametric coordinates of the
|
||
|
|
* Bezier wedge or for the triangular base and vary between 0 and 1. The
|
||
|
|
* third parametric coordinate is between the two triangular faces and goes
|
||
|
|
* from 0 to 1 as well.
