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.
