# Usage

vtkWedge is a concrete implementation of vtkCell to represent a linear 3D wedge. A wedge consists of two triangular and three quadrilateral faces and is defined by the six points (0-5). vtkWedge uses the standard isoparametric shape functions for a linear wedge. The wedge is defined by the six points (0-5) where (0,1,2) is the base of the wedge which, using the right hand rule, forms a triangle whose normal points outward (away from the triangular face (3,4,5)).

To create an instance of class vtkWedge, simply invoke its constructor as follows

      obj = vtkWedge

# Methods

The class vtkWedge has several methods that can be used. They are listed below. Note that the documentation is translated automatically from the VTK sources, and may not be completely intelligible. When in doubt, consult the VTK website. In the methods listed below, `obj` is an instance of the vtkWedge class.

- `string = obj.GetClassName ()`
- `int = obj.IsA (string name)`
- `vtkWedge = obj.NewInstance ()`
- `vtkWedge = obj.SafeDownCast (vtkObject o)`
