[vtkusers] FunctionValues is missing from the Python binding of vtk-5.10??

[Guillaume Jacquenot]

Dear VTK users,

I would like to use an instance of class

* vtkCellLocatorInterpolatedVelocityField with Python.*


*I manage to create an instance, but I can' access the main function
FunctionValues*


*I guess it is possible since I succeeded doing it with C++.*

*Any help appreciated!!*

I know this problem was already reported by Yifei Li on VTK mailing list
with VTK 5.8, but I found no answer.

I am working on Windows with Python 2.7 and the package VTK compiled by
Christoph Gohlke
http://www.lfd.uci.edu/~gohlke/pythonlibs/#vtk

Below is the function I use to create an instance of
vtkCellLocatorInterpolatedVelocityField from a vtkMultiBlockDataSet

def createVtkCellLocatorInterpolatedVelocityField(multiBlockDataSet, field
= 'Velocity'):
    cl = vtk.vtkCellLocator()
    clivf = vtk.vtkCellLocatorInterpolatedVelocityField()
    clivf.SetCellLocatorPrototype(cl)
    if VTKMajorVersion <= 5:
        clivf.SelectVectors(field)
    else:
        # clivf.SelectVectors(vtkDataObject::FIELD_ASSOCIATION_POINTS,
vMBDS_getFieldArrayName(multiBlockDataSet));
        pass
    iter = multiBlockDataSet.NewIterator()
    iter.InitTraversal()
    while iter.IsDoneWithTraversal() == 0:
        dataObj = iter.GetCurrentDataObject()
        if dataObj.GetNumberOfCells() > 0:
            cdTPD = vtk.vtkCellDataToPointData()
            cdTPD.RemoveAllInputs()
            if VTKMajorVersion <= 5:
                cdTPD.SetInput(dataObj)
            else:
                cdTPD.SetInputData(dataObj)
            cdTPD.Update()
            clivf.AddDataSet(cdTPD.GetOutput())
        iter.GoToNextItem()
    del iter
    return clivf
