Just looking at a propective job where effects will be added to an eye ball, just had a quick go here but cannot get any good track points from my eye.
 
Any suggestions, apart from a contact lens, which would be very difficult to draw track points on.
 
Thanks in advance.

hi chris
i'd suggest solving your problem with a simple 2dtrack (pupil)
that's how it's usually done.. i've never heard of somebody matchmoving a complete eye. i guess it would be very difficult to do because of missing parallaxe
 
please tell a bit more about your shot.. maybe there are other solutions
eg: will it be a strong closeup of an eyes (maybe full screen)?

Yes its a complete close up of the eye full screen, however you are right there is no parallax.  A 2d track is the best solution.
 
Thanks for your help.
