Yes. I wrote this class to interpolate points on the mesh. You may want to take a look at its concrete subclasses (vtkPolygonalSurfaceContourLineInterpolator) and at the test : <div><br></div><div>Widgets/Testing/Cxx/TestDijkstraGraphGeodesicPath.cxx to trace contours on a surface mesh. It is meant to be used in conjunction with a vtkContourWidget and is capable of giving you the new polydata (see vtkContourRepresentation::GetContourRepresentationAsPolyData()). </div>
<div><br></div><div>You may also get the contour pointIds itself as point ids on the original mesh on which the contour was traced. See vtkPolygonalSurfaceContourLineInterpolator::GetContourPointIds( vtkContourRepresentation *rep, vtkIdList *idList );</div>

Do you know if it can actually output points or polydata? I would ideally<br>
like to create a new polydata using the contour line as a boundary.<br>
<br>
Thanks!<br>
