vtkPolyData subclass

See original GitHub issue

Hello, and thanks for the incredibly useful project!

I have a class called TSurf() derived from vtkPolyData. Basically it is a standard PolyData, plus some simple attributes I use to store metadata. However, when I try to show one instance of the class in vtkplotter, I get a warning and nothing is shown:

Error: cannot build mesh from type:
 <class 'pzero.objects_factory.TSurf'>

This is what I get if I do a print(MY_OBJECT), so it should be OK:

Hello, I have changed line 120 of mesh.py to:

elif isinstance(inputobj, vtk.vtkPolyData):

and line 129 to:

elif isinstance(inputobj, vtk.vtkStructuredGrid) or isinstance(inputobj, vtk.vtkRectilinearGrid):

It works perfectly.

Thanks for all!
