Detailed Description

Base class to place points given constraints on polygonal data.

vtkPolyDataPointPlacer is a base class to place points on the surface of polygonal data.

Usage:
The actors that render polygonal data and wish to be considered for placement by this placer are added to the list as
placer->AddProp( polyDataActor );
