'''3D tracking''' is the tracking of an object's position and orientation in a three-dimensional space.
'''3D tracking''' is the tracking of an object's position and orientation in a three-dimensional space.
−3D tracking can be done in three major categories: [[electromagnetic tracking]], inertial, and optical.
+3D tracking can be done in three major categories: [[electromagnetic tracking]], inertial tracking, and optical tracking, which is also known as camera-based tracking.
It is also known as six degree of freedom tracking, for the six total degrees of freedom: three of rotation and three position.
