[Paraview] Why does this programmable source not work outside the paraview GUI

[Louis at M-Tech]

Hi All,

 

Why does this piece of code containing a programmable source not work
OUTSIDE the paraview GUI?

 

a) When the source is changed to ConeSource() it works (see Label 1 in the
code below).

 

b) Also when the Script content is pasted inside the paraview GUI scripting
editor, it does work - so the script contents itself is ok.

 

When the code is run directly from a python command line only an empty
graphis window is displayed - as if the script part is faulty.

 

Thanks in advance,

Louis

 

HERE IS THE EXAMPLE:

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

from paraview import servermanager

connection = servermanager.Connect()

pgsrc=servermanager.sources.ProgrammableSource()

 

 

pgsrc.GetProperty("Script").SetElement(0, """

 

import vtk

pts=vtk.vtkPoints() 

pts.Initialize()

pts.InsertNextPoint(0,0,0)

pts.InsertNextPoint(1,0,.0)

pts.InsertNextPoint(2,1,0)

pts.InsertNextPoint(3,3,0.)

 

cel=vtk.vtkCellArray() 

cel.Initialize()

cel.InsertNextCell(4) # number of points

cel.InsertCellPoint(0)

cel.InsertCellPoint(1)

cel.InsertCellPoint(2)

cel.InsertCellPoint(3)

 

output = self.GetOutput()

output.SetPoints(pts)

output.SetStrips(cel)

 

""")

 

 

view = servermanager.CreateRenderView()

 

# This programmable source pgsrc does not display

rep = servermanager.CreateRepresentation(pgsrc,view)

 

# Label 1: This source do display

#coneSource = servermanager.sources.ConeSource()

#rep = servermanager.CreateRepresentation(coneSource,view)

 

 

view.StillRender()

view.ResetCamera()

view.StillRender()
