Summary0011686: D3 crashes when points are stored double precision and ghost cells are on
DescriptionThis only happens when points are stored as double precision and ghost cells are required.
Steps To ReproduceThis Python extract demonstrates the problem (you will need to start you parallel server and connect to it at the top):

8<---------------------------------------------------
# connect to the parallel server (2 procs are enough)

Sphere1 = Sphere( guiName="Sphere1", EndTheta=360.0, Center=[0.0, 0.0, 0.0], StartTheta=0.0, PhiResolution=38, Radius=0.5, ThetaResolution=38, EndPhi=180.0, StartPhi=0.0 )
ProgrammableFilter3 = ProgrammableFilter( guiName="ProgrammableFilter3", OutputDataSetType='Same as Input', RequestInformationScript='', Script='pdi = self.GetPolyDataInput()\npdo = self.GetPolyDataOutput()\nnewPoints = vtk.vtkPoints()\nnewPoints.SetDataTypeToDouble()\nnumPoints = pdi.GetNumberOfPoints()\nfor i in range(0, numPoints):\n coord = pdi.GetPoint(i)\n x, y, z = coord[:3]\n x = x * 1\n y = y * 1.3\n z = z * 0.3\n newPoints.InsertPoint(i, x, y, z)\npdo.SetPoints(newPoints)', PythonPath='', CopyArrays=0 )
D32 = D3( guiName="D32", BoundaryMode='Duplicate cells', MinimalMemory=0 )
ProcessIdScalars3 = ProcessIdScalars( guiName="ProcessIdScalars3", RandomMode=0 )
Show()
Render() # this works
ExtractSurface2 = ExtractSurface( guiName="ExtractSurface2", NonlinearSubdivisionLevel=1, PieceInvariant=1 )
Show() # now that ghost cells are required and D3 is rerun it crashes
--------------------------------------------------->8
Additional InformationIn GetGhostPointIds the local variable called processId is getting set to -1 and then used to index an array. On lines 3752 & 3753 is where this happens:

    regionId = kd->GetRegionContainingPoint(pt[0], pt[1], pt[2]);
    processId = kd->GetProcessAssignedToRegion(regionId);

The point might be outside due to rounding a double to a float at some point? It is very close to an actual point.

 I tried it out on my machine and didn't encounter any problems. I'm using the latest version of ParaView checked out on 1/12/11. What version of ParaView are you using? Can you try updating ParaView and see if you're still getting the problem since I'm not sure how I'm going to reproduce it otherwise? If it still isn't working for you, let me know the details of your machine, compilers, ParaView SHA, etc.

 Sorry, I had a typo in the programmable filter that I didn't notice. I'm able to trigger the problem.

 It was a problem in vtkPKdTree. I fixed it by expanding the bounding box slightly. It will take a couple of days before it filters up to paraview and for me to check that it works properly everywhere. I'll mark it as resolved when this happens.

 Thanks - I've applied the patch and it is working for me.

 ParaView's VTK SHA is now updated to include the fix so this should work properly now.

Paul, please close this issue if everything is working fine for you.
