PlanarTracker (NukeX only) is a powerful tool for tracking surfaces that lie on a plane in your source footage. The size of plane is not important as the track relies on the amount of texture in the region - the more texture, the more features can be picked up, the better the track. PlanarTracker can handle approximately 40% of the surface being covered at any one time, but if the plane is fully obscured, you can manually correct the plane by moving it to a frame where it is not obscured and resume tracking from there.

You can also use your tracking results to replace the tracked plane with an image, or link to a GridWarp node to manually transform a warp or morph function.
