None | Disables the view platform behaviors. |
Hover | Allows you to move to any point in 3 space, with mouse controls for moving forward, backward, and translation along the x and y axis. |
Drive | Similar to Hover, but places the viewer on the ground. |
Fly | Allows you to move to any point with any orientation in 3 space, with mouse controls for moving forward, backward, translation along the x and y axis, and yaw, pitch, and roll. |
Orbit | Allows you to "orbit" the view about the scene. The scene appears to rotate and tumble, but it is really the view that is changing. |
