Do your points have any structure? That is, are they on a grid or
anything like that? You can take a look at this information:
http://www.vtk.org/Wiki/VTK/Tutorials/3DDataTypes - perhaps your data
fits one of those models. If you just have "unorganized points", I'd
use a vtkPolyData for storage, and the order is unimportant (unless
you have topology/cells (like polygons, etc) which reference the
points, then you just have to make sure your cells reference the
correct point ids).
