3D tracking really simplifies many compositing tasks, whether it's removing unwanted objects or adding in additional elements. Having to swap applications in order to obtain the necessary camera data has always been time consuming and making alterations difficult. Now, Nuke comes with its own camera tracker - so 3D tracking can be done exactly where you need it! Focus on Nuke's camera tracker and learn other relevant tasks for a good track, i.e. grain/noise, lens distortion and 2d tracking. After analyzing the point cloud and solving the camera movement, learn how to set-up some geometry and recreate the scene with 3D and UV projections, then animate a new camera movement which will turn that into a stereoscopic set-up and end up with a nice (red & blue) anaglyph for a stereoscopic workflow alternative.
