Advanced Stereo Workflows in Toxik: Disparity

In this series of lessons we'll learn a technique to convert a Depth pass from a 3D application into a Disparity map. We'll then learn how to create tools to use this map to set the zero parallax point automatically and set depth correctly on 2D layers, like text. We'll begin this project by learning about what stereo disparity maps can do inside Toxik. After that, we'll learn what a disparity map is and how to convert a depth map into a stereo disparity map. Then we'll dive right in and learn the mathematical relationship between depth and disparity maps and learn how to offset and multiply our depth into a pixel offset value. With our disparity map created, we will be able to create a depth controller to change our scene depth within two mouse clicks. We'll finish by learning how to use our disparity values to automatically update stereo offset using expressions. Software required: Toxik 2010 for project files.
