In this series of lessons we'll learn how to use the 3D Camera Tracker in NukeX. This tool lets us track our live-action footage and create a camera in Nuke's 3D system that matches our real-life movement. This allows us to place 3D objects correctly and have the animation done automatically.

We'll begin this project by going through a simple camera track and learn the proper workflow to get a usable 3d scene and camera. We'll then learn how to add Nuke 3D geometry into our scene as well ass geometry we import from another application. We'll then learn about the various properties and pipes in the camera tracker that let us control our tracks better. After getting a track, we'll learn how to use the DepthGenerator node to take our 3D camera and generate a rough Depth map for our footage. We'll then learn how to convert a 3d point back into 2d space so we can drive 2d transforms in our nodes.
