I'm no expert, but what I see in Blender's new planar track looks very
different from Mocha "under the hood". They are both tracking image
patches, but Blender is tracking patches one-by-one and then fitting a
plane-onto-them while Mocha appears to be associating affine trackers with
a plane, and then solving (and potentially disqualifying) them together
with the planar constraint.

The difference in error bounds and flexibility between these two approaches
seems very big. This is probably a big part of why Mocha is able to
auto-generate the tracking patches.

At least that's the way I see it.

Which is not to say that the new Blender stuff is not awesome. It looks
awesome. It just doesn't look like Mocha "under the hood". Of course what
do I know, I didn't write Mocha, and all I saw was that video.. :)
