Example of vtkProgrammableGlyphFilter in Python

Is it possible to provide an example of vtkProgrammableGlyphFilter in Python? I’m not sure how to handle the void function pointer.

I have just created an example based on the C++ version. Please see ProgrammableGlyphFilter.

Essentially you just create an observer and define a __call__ method. Also the class is initialised with the vtkProgrammableGlyphFilter via the __init__() method so there is no need to check for existence etc.

Also ProgrammableGlyphs may be of use.
