[vtkusers] How to pick points that falls inside a polygon?

[Jim Peterson]

How are you proving that the unselected points should be within the 
polygon? how many points are you using to define the selection polygon?

It sounds like you want some descendant from vtk3dWidget 
http://www.vtk.org/doc/nightly/html/classvtk3DWidget.html maybe 
vtkSplineWidget to create the selection polygon.
