[vtkusers] vtkCollisionDetectionFilter with 2 vtkActor (line and palne)+translation

[Goodwin Lawlor]

Hi Mark,

You should use a callback to color the plane etc.

Have a look at the example here:
https://github.com/glawlor/vtkbioeng/blob/master/Testing/Cxx/TestCollisionDetection.cxx

Feel feel to ask further if the code isn't clear.
