Navigation Panel

Parent Previous Next

This panel is divided into two sections, “Viewpoint” and “Control”.



The “Viewpoint” section holds information about the position and orientation of the camera, whereas “Control” allows the selection of the flight mode, maximum speed and collision detection.

Most of the displayed values can also be changed manually.


The image on the left contains a thumbnail overview of the currently loaded terrain in which a crosshair shows the cameras current position. When a point in this map is clicked at, the camera will jump to the corresponding position in the scene.

Vertical mouse movement while pressing the right mouse button changes the zoom factor. This can also be done using the mouse wheel while the mouse pointer is inside the 2D map area. The current magnification is displayed in the top left corner.


Information about the cameras position is also displayed by the altimeter and the text fields next to it. The cameras position can also be changed by sliding the bar in the altimeter, or by manually entering new coordinates into the text fields.

Clicking the symbol consisting of four arrows moves the camera back to its original position.




The compass represents the viewing direction. This value can be manipulated either by dragging the compass needle or by entering the desired viewing direction into the text field below it.




Similarly, the pitch control shows the current tilt of the camera, but can also be used to change it.


The section labeled “Control” pertains to motion control. The various navigation modes differ in the use of the mouse and in the manner of the motion.

In “View mode”, the mouse is used to navigate freely above the terrain. The illustration below explains how to drag the mouse to achieve the desired motion. The “View mode” shortcut is Ctrl + Shift + V














“Sphere mode” is designed for spherical terrains and is only available in TerrainView-Globe™.  The left mouse button is used to drag the terrain, the middle mouse button is used to orbit around the point on the surface underneath the center of the screen and the right mouse button is used to move towards or away from (zoom) the terrain. The mouse wheel can also be used for zooming.


“Explore mode” is used to investigate a selected object. Dragging with the left mouse button moves the viewpoint around the object always keeping it in focus. Dragging with the right mouse changes the distance to the object. The “Explore mode” shortcut is Ctrl + Shift + E

This mode can also be activated by holding the X key pressed. This way, a quick switch to the explore mode can be made while in another navigation mode.


When “Low level mode” is activated, the navigation is the same as in “View mode”, but the altitude over ground (AOG) is constantly clamped to the value in the corresponding text field. The altitude is visually represented by the horizontal bar in the image, which can also be used to change the altitude. The “Low level mode” shortcut is Ctrl + Shift + L







In “Joystick mode”, a joystick is used to navigate. The joystick navigation modes can be defined in the options dialog, see section 5.1.4. The “Joystick mode” shortcut is Ctrl + Shift + J




The needle in the speed control determines the maximum allowed speed. The current speed is displayed directly below it. The maximum allowed speed can be changed by dragging the needle or entering a value in the text field. Depending on the size of the currently loaded terrain it may be desirable to set a low maximum speed so as not to fly across the terrain too quickly.

Note: By default, a feature called auto max speed is enabled (see section 5.1.5) which automatically sets an appropriate velocity based on the camera altitude. Changing the speedometer settings manually will disable this feature. If a faster or slower motion is desired, the mouse wheel should be used. This way, only the auto max speed scale is changed.


A doubleclick with the left mouse button on a point in the 3D View will perform an automatic flight towards that point.

A doubleclick with the right mouse button in the 3D View will rotate the camera towards north.
