[vtkusers] drawing isolines

[Cory Quammen]

Rashed,

vtkContourFilter should be able to take a vtkPolyData as input and
produce isocontours as you desire, e.g.

vtkContourFilter *filter = vtContourFilter::New();
filter->SetInputConnection(polyDataSource->GetOutputPort());
filter->SetNumberOfContours(...);
filter->SetValue(0, ...);
...
