'''3D tracking''' is the tracking of an object in three dimensions of space. It is more useful to talk about [[3DOF]] tracking or [[6DOF tracking]].

+3D tracking can be done in three major categories: inertial, magnetic, and optical.
For a rigid body that has physical size, like a wooden block, it can be rotated on three axes, and positionally shifted on three axes, for a total of six degrees of freedom, also known as [[6DOF]].
