Contour interpolator for to place points on polygonal surfaces.
vtkPolygonalSurfaceContourLineInterpolator interpolates and places contour points on polygonal surfaces. The class interpolates nodes by computing a graph geodesic laying on the polygonal data. By graph Geodesic, we mean that the line interpolating the two end points traverses along on the mesh edges so as to form the shortest path. A Dijkstra algorithm is used to compute the path. See vtkDijkstraGraphGeodesicPath.
The class is mean to be used in conjunction with vtkPolygonalSurfacePointPlacer. The reason for this weak coupling is a performance issue, both classes need to perform a cell pick, and coupling avoids multiple cell picks (cell picks are slow).
- Warning
- You should have computed cell normals for the input polydata.
