<p class=MsoNormal>A pipeline to place labels at points in 3D space can be the
following:<br>
vtkVectorText -> vtkPolyData -> vtkFollower<br>
you must call the vtkFollower SetCamera method to make the follower adjust its
orientation according to the camera movement<br>
For better control it is good to add all the followers into a vtkCollection<br>
As expected it is a slow method when placing too many followers on screen.<br>
<br>
For an outline of an unstructured grid the simple vtkOutlineFilter can be used
- which creates a box based on the grid bounds<br>
