bug in vtk-4.3.0-1.cvs20030620

When I run the following script under win xp, there is no problem. But under linux, I've got a grey scale render instead of a coloured one.

import vtk reader = vtk.vtkUnstructuredGridReader() reader.SetFileName('./essai.vtk') reader.Update() lut1 = vtk.vtkLookupTable() lut1.SetHueRange(0.667, 0.0) dataMapper = vtk.vtkDataSetMapper() dataMapper.SetLookupTable(lut1) dataMapper.SetInput(reader.GetOutput()) drange = reader.GetOutput().GetScalarRange() dmin = drange[0] dmax = drange[1] dataMapper.SetScalarRange(1.2, 2.5) dataActor = vtk.vtkActor() dataActor.SetMapper(dataMapper) ren = vtk.vtkRenderer() ren.AddActor(dataActor) ren.SetBackground(1,1,1) renWin = vtk.vtkRenderWindow() renWin.AddRenderer(ren) renWin.SetSize(500, 500) iren = vtk.vtkRenderWindowInteractor() iren.SetRenderWindow(renWin) iren.Initialize() iren.Start()

And the file essai.vtk :
