At the risk of pointing out something that has probably already been =
fixed in the CVS version of the code, I believe there is an error in the =
itkPointSet class, v1.0. The GetNumberOfPoints() method does the =
following:

return m_PointsContainer->Size()

but if no points have been added to the pointset, then m_PointsContainer =
has not yet been constructed and the method causes an exception to be =
thrown. Perhaps m_PointsContainer could be initialized to NULL, and then =
GetNumberOfPoints() would return 0 if m_PointsContainer is NULL?

Best regards,
-Parag Chandra
