vtkPolyData format, it populates its POINTS list and the index to that
point list is used further to populate POLYGONS list and so on
.<BR><BR>Could you please tell me from which point of a given model, vtk starts
populating its point list.To put it other way, which point of the whole data set
becomes the first to appear in the Point list of vtkPolyData. For example,why
did vtk started to populate the POINTS list from 0.0, 0.0, 0.0 in the following
listing; why not some other point.<BR><BR><BR><BR># vtk DataFile Version
