Hi,

If I want to use a vtkStructuredGrid as input to vtkContourFilter, do I need
more than points and scalars? At the moment vtkContourFilter just gives me a
segmentation error. This is what I'm doing...


 vtkStructuredGrid* grid = vtkStructuredGrid::New();
  grid->SetDimensions(dims[0],dims[1],dims[2]);
  grid->SetPoints(points);
  grid->GetPointData()->SetScalars(scalars);

 vtkContourFilter* contour = vtkContourFilter::New();
  contour->SetInput(grid);
  contour->GenerateValues(2,0,1);


Perhaps someone has an example (in any language) of how to create a simple
vtkStructuredGrid which is suitable for contouring?

Thanks,
