[Insight-users] Use of PointSet and VectorContainer in python

[Roel Zinkstok]

Hi Matt,

Thanks for your response!

I already have that document, and ik does give a lot of info on images but
not on pointsets or meshes, unfortunately...

Using print itk.VectorContainer.keys() gives even more usefull information.
That shows that Python(x,y) has the following types are supported for the
VectorContainer:

(<itkCType unsigned int>, <class 'itkLevelSet.itkLevelSetNodeUS3'>),
(<itkCType unsigned int>, <class 'itkLevelSet.itkLevelSetNodeF3'>),
(<itkCType unsigned int>, <class 'itkLevelSet.itkLevelSetNodeUC3'>),
(<itkCType unsigned int>, <class 'itkLevelSet.itkLevelSetNodeUS2'>),
(<itkCType unsigned long>, <class 'itkVector.itkVectorD3'>),
(<itkCType unsigned int>, <class 'itkLevelSet.itkLevelSetNodeF2'>),
(<itkCType unsigned long>, <class 'itkVector.itkVectorD2'>),
(<itkCType unsigned int>, <class 'itkLevelSet.itkLevelSetNodeUC2'>)


So it seems I cannot use itk.Point for elements in the container. I guess
that prevents me from building a PointSet then?
Funny thing is that when I create a Pointset, and then request its
pointscontainer, I get a pointer to a VectorContainer that is templated over
Points, if I am not mistaken:


pointset.GetPoints()


results in:

'_80e2a804_p_itk__VectorContainerTunsigned_long_itk__PointTdouble_3u_t_t'


I have no clue how to use this pointer though... would that be an option?
