Navigation controls are used to control camera view. What the user sees on the screen is defined as the camera’s view or the observer’s view.

There are six different classes of navigation controls:

1. Selecting an Object

To select an object means to set it as the new target for whatever function users wish to perform. This section goes over different ways to perform this functions with all objects.

2. Centering an Object

To center an object means to set that object as the pivot around which all camera movement will be fixed. This section goes over different ways to perform this function with all objects and clarifies the difference between centering an object in view and setting an object as the center.

3. Selecting Camera Frame

To select a camera frame means to select a different frame in which camera position and orientation is fixed. All frames are fixed relative to the current central body. This section describes the four different camera frames available  and details how to use each one.

4. Rotating Camera

To rotate the camera means to adjust the camera’s orientation without changing the position of the camera. This section goes over the different methods to rotate the camera.

5. Moving Camera

To move the camera means to adjust the camera’s position from its default fixed position, with or without rotating the camera. This section goes over the different methods to move the camera.

6. Using Vector to Set Camera View

Vectors can also be used to simultaneously change the camera’s frame, position, and orientation. This section details how to adjust camera view through the use of a vector.
