Hi Bastil, I did something similar where I was calculating the wall distance for a volume. You can create a filter that takes two inputs. First build a vtkCellLocator with one input. Then iterator over the points in the other input and use the FindClosestPoint method.
Note: this is quite slow. Regards, Paul 2009/10/4 [email protected] <[email protected]> > True. However, I have no 1:1 correspondance since geometries have > certain areas where they differ.
