[vtkusers] Select viewed vertices

[Eric E. Monson]

Hey Rachel,

vtkHardwareSelector is probably what you want:

http://www.vtk.org/doc/nightly/html/classvtkHardwareSelector.html

There is a reasonable example here:

http://www.vtk.org/Wiki/VTK/Examples/Cxx/Broken/Filtering/ExtractVisibleCells

and some discussion of limitations and some Python code in this thread from October:

Talk to you later,
-Eric
