Hello world.

After I have finally found a way of making the vtkContourFilter work I'm now
facing how to color them.
I want to color them according to the value they are having.
Example: The cutting plane displays the "right" color for the scalar data,
but the iso-surfaces (contours) are colored identically.
Have a look at the screenshot in the attachment.

So, what do I have to do, to set up the right coloring?

Here is the code I am using to create the contours:

vtkContourFilter *scalarIsoSurface = vtkContourFilter::New();
scalarIsoSurface->SetInput(sGridPointData->GetOutput());
scalarIsoSurface->SetValue(0,3);
scalarIsoSurface->SetValue(1,5);
scalarIsoSurface->Update();

vtkPolyDataNormals *sGridPolyDataNormal = vtkPolyDataNormals::New();
sGridPolyDataNormal->SetInput(scalarIsoSurface->GetOutput());
sGridPolyDataNormal->Update();

vtkPolyDataMapper *scalarIsoSurfaceMapper = vtkPolyDataMapper::New();
scalarIsoSurfaceMapper->SetInput(sGridPolyDataNormal->GetOutput());
scalarIsoSurfaceMapper->Update();

vtkActor *scalarIsoSurfaceActor = vtkActor::New();
scalarIsoSurfaceActor->SetMapper(scalarIsoSurfaceMapper);

Have a nice day.
Sebastian
