Subject: [vtk-developers] Confusing error message in vtkKdTree

In vtkKdTree, the member variable LocatorPoints is created in BuildLocatorFromPoints.

If you call FindClosestPoint without calling BuildLocatorFromPoints, the error generated (line 2203) is

"vtkKdTree::FindClosestPoint: must build locator first"

Can we change this to

"vtkKdTree::FindClosestPoint: must call BuildLocatorFromPoints first"

As it is, it is very confusing, since a BuildLocator function also exists.

Thanks,

David
