I don't think there's anything wrong. The sphere has radius of 50 (remember that the sphere is just a surface mesh and not a volumetric mesh) and you're asking to find all points within radius 25 of the center of the sphere which there are none. <br>

Hi all,<br>
<br>
Does anyone have an example for vtkPointLocator.FindPointsWithinRadius()<br>
<br>
I am having trouble with it, here is my code<br>
<br>
x=vtk.vtkSphereSource()<br>
x.SetRadius(50)<br>
x.SetPhiResolution(50)<br>
x.SetThetaResolution(50)<br>
x.Update()<br>
<br>
<br>
<br>
result=vtk.vtkIdList()<br>
Loc=vtk.vtkPointLocator()<br>
Loc.SetDataSet(x.GetOutput())<br>
Loc.FindPointsWithinRadius(25,[0,0,0],result)<br>
<br>
prints<br>
result None<br>
<br>
Any hint?<br>
<br>
I think using this vtkFindLocator/KDTree there should be some method to get<br>
the points inside a polygon of any shape?<br>
<br>
Thanks<br>
<br>
Jothy<br>
