[vtkusers] Programmable source not visualized

[Favre Jean]

you are pretty close to the solution. Remember to set the "output dataset type" to vtkUnstructuredGrid (at the top of the ProgrammaableSource panel, and substitute your code

# Add the points and hexahedron to an unstructured grid
uGrid = vtk.vtkUnstructuredGrid()
uGrid.Allocate(1,1)
uGrid.InsertNextCell(hex_.GetCellType(), hex_.GetPointIds())
uGrid.SetPoints(points)
uGrid.GetPointData().SetScalars(scalars)

with this code, which makes use of the predefined object called 'output"

output.Allocate(1,1)

output.InsertNextCell(hex_.GetCellType(), hex_.GetPointIds())

output.Points = points

output.PointData.SetScalars(scalars)
