[vtkusers] vtkWarpScalar. Should it work?

[Nico Vermaas]

Hi,

- Can anybody see what is wrong?
- I want to use vtkWarpScalar to display an elevation picture of my scalars. 
- According to the examples and the manual I should first convert my vtkImageData to vtkPolyData and then perform the warp.
- For some reason the 'SetInput' memberfunction of warp does not seem to exist (see errors). Has it changed in VTK4?
- Does anybody have a working example of warping?

vtkImageDataGeometryFilter *geometry = vtkImageDataGeometryFilter::New();
 geometry->SetInput(myExtractVOI->GetOutput());

 vtkWarpScalar *warp = vtkWarpScalar::New();
 warp->SetInput(geometry->GetOutput());

------------------------
ERROR:
