[vtkusers] vtk python, point picker, UseCellsOff attribute error

[redmod79]

When using vtkPointPicker in python (vtk 6.1), trying to use UseCellsOff and
related methods results in an attribute error... it seems like using cell
points is on by default, and I don't want it to be... I want to be able to
pick the raw points created as shown below and not the cell points (ids 1,
2, 3, 4 of the cell)

points = vtk.vtkPoints()
... points added

ugrid = vtk.vtkUnstructuredGrid()

ugrid.SetPoints(points)

for i in range(cell_count):
    cell = some cell created using points
    ugrid.InsertNextCell(cell)

mapper = vtk.vtkMapper()
mapper.SetInputData(ugrid)
actor = vtk.vtkActor()
actor.SetMapper(mapper)

renderer = vtk.vtkRenderer()
renderer.AddActor(actor)

... in another part of the code using a custom interactor style

picker = vtk.vtkPointPicker()

picker.UseCellsOff() ... this causes the attribute error



doing print dir(picker) shows no methods UseCellsOff or related methods

Thank you for your help.
