Detailed Description

Implicit function that is generated by extrusion of a polyline along the Z axis.

vtkPolyPlane is, as the name suggests, an extrusion of a vtkPolyLine. The extrusion direction is assumed to be the Z vector. It can be used in combination with a vtkCutter to cut a dataset with a polyplane. vtkPolyPlane is a concrete implementation of the abstract class vtkImplicitFunction.

Todo:

Generalize to extrusions along arbitrary directions.
