Stereoscopic 3D basics

Before we open up Maya, let's take a look at some stereoscopic 3D basics. There are three terms you need to be familiar with. The first is intraocular distance. Second, zero parallax plane. And the third is stereo type. The reason we have the perception of depth in our vision is that our right and left eye record a slightly different version of the scene in front of us. How different the scene your eyes record is profoundly influenced by the interocular distance, or the distance between your two eyes. On most humans, the interocular distance is around 63 millimeters, or 2.5 inches. When you're inside of Maya, you're not dealing with human eyes, but with cameras, and Maya calls that the interaxial distance. But whether you're dealing with cameras or human eyeballs, that interaxial distance is generally based on the distance between two human eyes. Inside of Maya, you can change that interaxial distance to whatever you want. However, if you have the interaxial distance too far apart…
