I two irregular contours (polylines) and I would like to determine the "mean
place" between them.Probably the "easiest" way to do it is to start by
computing the mean place for each contour, independently.So now my problem is:
having a set of points, how to compute the mean geometric plane, ie the plane
minimizing square distances of points to itself.Actually I just need 2 vectors
lying on the place, from which it would be easy to define a new space.I did not
find such a method in VTK (I am writing a plugin so I just need a VTK method,
not a PV filter) but I suspect that the plane vectors could be extracted from
the result of vtkPCAAnalysisFilter::GetParameterisedShape() or
vtkPCAAnalysisFilter::GetShapeParameters().Am I wrong?Any suggestion for my
problem?
