I've just done a stereo job using the planar tracker,
which required footage being put in monitors, shot on an epic rig, & had one
corner of the screen leaving shot on a
couple of occasions, & found the track to be solid, as so much of the planar
surface was still exposed to the tracker

Subject: Re: [Nuke-users] CameraTracker to PlanarTracker
with planar tracker when it looses its why by objects passing in front of you
just do the same as a 2d tracker, find a small section of something else
roughly in the same plane track it for a few frames till the objects passes by,
and then move the tracking spline back to where it was before.

So there are a couple of instances where PlanarTracker gets pretty confused.
For example, say you are trying to track a television set which moves out of
frame. This would confuse PlanarTracker, or it least it does in my limited
experience using the tool.
