Finally, most of the other interfaces give at least 5 degrees of freedom to the user: 3 being the coordinates of the camera's position, and 2 being the angles (assuming the up vector is unchangeable, some interfaces might allow that, giving a sixth degree of freedom).
The most common controls are the trackball controls where the user rotate the object like a ball
#link("https://threejs.org/examples/?q=controls\#misc_controls_trackball")[(live example here)] and the orbit controls, which behave like the trackball controls but preserving the up vector #link("https://threejs.org/examples/?q=controls\#misc_controls_orbit")[(live example here)].

These types of controls are notably used on the popular mesh editor #link("http://www.meshlab.net/")[MeshLab] and

These controls are typically used in shooting video games, the mouse rotates the camera and the keyboard translates it.
