Chris and Trish Meyer note that you are able to export the results of the new 3D Camera Tracker to any application that has a way to accept After Effects keyframe data in this article showing how to do just that.
Check out the tutorial for Exporting 3D Camera Tracker Data from After Effects CS6 to Cinema 4D here.
Chris and Trish Meyer write: you can track a piece of footage, export the camera data as well as the location of objects in the scene to a 3D program, add new geometry such as a facade, aircraft, or (please don’t) a dinosaur, render the new 3D objects, and then bring those back into After Effects to composite into the scene.

I am glad this plugin is now available, but I used it today and had problems… There were several keyframes that were missing once the camera data was imported from AE to C4D… My coworkers and I built a scene in AE and wanted to use a 3D logo that we made in cinema 4D, but once the render came out of cinema, the logo didn’t quite stick to the null from AE even though it was lined up perfectly with it. Also, the camera stopped animating in Cinema after 53 frames even though the AE camera animated for 72 frames…
