What You’ll Learn in This Chapter
To start off, we’ll learn how to orient ourselves in 3D. I’ll cover how Processing positions the 3D axes relative to the screen and show you how to draw some basic 3D shapes in different positions in this space so you can get a feel for this system. Next, we’ll start working with the Kinect point cloud data. I’ll show you how SimpleOpenNI represents this 3D data as vectors, and we’ll learn what vectors are and how to work with and display them. Once we’ve got a basic point cloud on the screen, the next step is to be able to move it around. I’ll teach you the basics of moving in 3D, how to rotate and translate our points so that we can look at them from different angles and distances.
At this stage, we’ll have a ...
