[vtkusers] vtkPointLocator FindPointsWithinRadius Example

[KS Jothybasu]

Hi all,

Does anyone have an example for vtkPointLocator.FindPointsWithinRadius()

I am having trouble with it, here is my code

x=vtk.vtkSphereSource()
x.SetRadius(50)
x.SetPhiResolution(50)
x.SetThetaResolution(50)
x.Update()



result=vtk.vtkIdList()
Loc=vtk.vtkPointLocator()
Loc.SetDataSet(x.GetOutput())
Loc.FindPointsWithinRadius(25,[0,0,0],result)

prints
result None

Any hint?

I think using this vtkFindLocator/KDTree there should be some method to get
the points inside a polygon of any shape?

Thanks

Jothy
