2.3 Using Multiple Views to Solve Nodal Pans

There is one special kind of camera motion, that requires additional views to extract any kind of 3D: Nodal pans. This tutorial explains what nodal pans are and how they are different from other camera movements. After that we will use the same technique shown in the live session to add additional camera views of the same scene in order to obtain a real 3D result.

2.1 Solving Multiple Cameras Into a Single Scene

When tracking multiple shots from the same location, it is often important that every shot shares the same coordinate system. This way we can ensure that key locations are identical independent of which camera solve is worked on. A straightforward way to ensure a shared coordinate system for multiple cameras is to track and solve them into the same scene in PFTrack.

Tracking an Object in PFTrack

Sometimes it is necessary to track motion other than the camera’s, for example to replace moving objects in a shot. In this tutorial you are going to track and solve a prop carried by an actor. You will learn how to use the User Track node to manually track an object…

Solving Nodal Pans in PFTrack

Nodal pans, where the camera is mounted on a tripod, provide a specific challenge to 3D camera tracking, due to the lack of parallax in the shot. In this tutorial, you will learn what that means when solving your camera, and how to use reference frames in order to…
