[vtkusers] Use vtkDistanceWidget with dicom series

[Richard Frank]

I am trying to do the same thing - that is, use the  vtkdistance measure tool so that it stays facing the camera like a vtkfollower - and only use a parallel projection. The documentation says that the VTK distance to the representation will stay in the upper layer, but I guess it's really only valid  for 2D? The VTK measure distance widget seems to always behave in a 3-D fashion. 

Our client finds the placing of the widget difficult in 3-D, or perhaps I should say confusing, once they move the camera around the widget is floating in space somewhere.

If anyone knows a way to change the behavior of the widget let me know....

Thanks

Rick
