[vtkusers] cutter for vtkGlyph3D

[alex Dowson]

Hi

Check you PDBReader FileName path . If is not locating file then output will be empty and you will get this error due to empty output. Also I still donot know
what is PDB format so is it triangulated polydata ?

Thank you.
But after I tried your method,I got this kind of error:

  Hi

  You can try like this

  plane = vtk.vtkPlane()
  plane.SetOrigin(0,0,0) 

  plane.SetNormal(0.17, 0, 0.9579)
  planeCut = vtk.vtkCutter()

  planeCut.SetInput(pdb.GetOutput())
  planeCut.SetCutFunction(plane)

  Sorry, I didn't say it clearly.
  I read the pdb by
  pdb = vtk.vtkPDBReader()
  pdb.SetFileName(sys.argv[1])

  And I want to cut the pdb by the plain and its cutter

  plane = vtk.vtkPlane()
  plane.SetOrigin(??????????????????????what should I put in here)
  plane.SetNormal(0.17, 0, 0.9579)
  planeCut = vtk.vtkCutter()
  planeCut.SetInput(????????????????????what should I put in here)
  planeCut.SetCutFunction(plane)


  Thank you!

    Dear ALL,
    I have a pdb file and I want to use the pdbreader to read the pdb file. And use use vtkGlyph3D for each atom (each points ) of the pdb. I want to use a plain to cut this pdb and show the cutting plain of the pdb. How do I combine vtkCutter and vtkGlyph3D to achieve the aim? Thank you.
