Yes, the contours use the positional information, as should all filters,

Does the vtkPolyData contour line / surface output from the vtkMarchingContourFilter preserve this spatial information? Thus, would finding the intersection of a line with a point on a contour return to the same (x,y,z) coordinates as of the corresponding point in the original vtkImageData set?
