You can find continuous edge by computing curvature for each point and connecting them using vtkDijkstraGraphGeodesicPath, as suggested before:

Get surface area of region on polydata

I would like to derive the surface area of a specific region on the surface of polydata. This specific region would be the part of the surface that is visible when viewed from above (in the y-plane) such that overlapping “points” are not considered. This is the isosurface generated by Marching Cubes: [original] To illustrate, I have derive this particular top-surface by manipulating the original image stack and use MC to reconstruct the isosurface of the manipulated images (in green): [pro…
