Description

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.

Introduction and Project Overview
Hello, I'm Chris with Digital-Tutors, an Autodesk authorized publisher. 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 a slate. We'll begin this project by learning about what stereo disparity maps can do inside of Toxik. We'll then learn what a disparity map is and how to convert a depth map into a stereo disparity map. We'll then dive right in and learn the mathematical relationship between depth and disparity and how to change our depth into a pixel offset value. With our disparity map created, we'll be able to create a depth controller to change our scene depth in only two clicks. We'll finish by learning how to use our disparity values to automatically update stereo offset using expressions. This series of lessons will illustrate an example of how to create an extremely powerful disparity map using a simple 3D depth pass and how to do it inside of Toxik. This technique only works on stereo projects that have depth information, so for a live action project this technique will not work unless you can create a depth map. But for all of our 3D projects, this lets us gain an incredible amount of control in Toxik. So with that, let's go ahead and get started.
