3D Rotation with Trackers and Trigonometry in NUKE
In this series of lessons, we'll learn how to use trackers and trigonometry to match rotation of an eye in NUKE's 3D system. Software required: NUKE 5.2 and up.
What you'll learn
In this series of lessons, we'll learn how to use trackers and trigonometry to match rotation of an eye in NUKE's 3D system. We'll then create an appealing final video using a few simple images and a variety of compositing and animation techniques. We'll begin this project by importing our elements and tracking various features of the face. Once we have a base of tracking data to work off of, we'll learn the basic math terms and ideas that we will use to translate our 2D tracker data into 3D rotation. We'll then learn how to take our mathematical equation, and translate it into an expression NUKE understands. Once we have our rotation expressions working, we'll finish our 2d elements using a variety of color correction, masking and animation techniques. Then we'll combine all our nodes using compositing math to correctly mix everything together. Software required: NUKE 5.2 and up.
