vtkKdTree::FindClosestPointWithinRadius returns points out of radius
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
The method vtkKdTree::FindClosestPointWithinRadius calls vtkKdTree::FindClosestPointInSphere, and the point returned can be out of the sphere, so out of the Radius passed as argument. There must be an additional test in one of these two methods to compare the distance between the points and the given radius.
