[vtkusers] Python FindClosestPoint

[Jean-Michel]

Thank you very much for your suggestion Andy. Using the FindPoint() method works well.

Is there a reason why I could not use FindClosestPoint() ? Does it come from the data type I am manipulating ?

Did you try using the FindPoint() method in the vtkUnstructuredGrid class? It's implemented in vtkPointSet.

Dear all,

 

I have an Unstructured Grid and I am trying to find the id of the closest point to a given point defined by three coordinates (x,y,z).

I tried using the FindClosestPoint function of the PointLocator, but it did not work so far. Running pid=vtk.vtkPointLocator.FindClosestPoint(x,y,z) returns "TypeError: unbound method requires a vtkPointLocator as the first argument".

 

I would appreciate if someone could explain to me what I am doing wrong or missing. Thanks in advance for your time.
