|

|
|
*
|
|
* vtkPolyDataPointPlacer is a base class to place points on the surface of

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