The settings for TerrainView™ are simply called “Options” and can be found in the “Tools” menu of the TerrainView™ menu bar.Crosshair

These settings define a cross in the exact middle of the 3D View.



Enabled: Turns the crosshair on or off.

Radius: The radius of the crosshair, in pixels.

Hole radius: The radius of the hole in the middle of the crosshair, in pixels. Can be 0.

Color: The color of the crosshair.

Opacity: The opacity of the crosshair.

Use to open POI links: The crosshair is used to “click” on Points of Interest when pointing at them for a few moments.

POI


Font quality: The quality of the font texture for points of interest. Changing this setting will only affect POIs created afterwards. If there are already POIs in the scene, the scene must be reloaded to apply the quality setting.

Info Board



These settings define the placement of information boards used by Points of Interest. An information board is displayed inside the viewport of the 3D view.

Alignment to viewport: Where to Info Board should be placed (top left, top right, etc...). "Automatic" places it next to the screen point the POI was clicked at.

Horizontal spacing to viewport: The amount of pixels the Info Board stays away from the right and left border of the 3D view.

Vertical spacing to viewport: The amount of pixels the Info Board stays away from the top and bottom border of the 3D view.

Joystick

If a joystick is available, an additional section can be found in the options dialog. These settings define the joystick navigation mode.

There are several joystick navigation modes, each of them is active during the assigned button is pressed. If the button is released, the mode with no button becomes active automatically.


Move mode: The user can move forward and backward and change the heading (yaw). The altitude remains constant.


Altitude mode: Only vertical movement is possible.



Rotate mode: Only the viewing direction can be changed. The option "Allow altitude change" simulates a pressed altitude mode-button allowing simultaneous rotation and change of altitude. The altitude is changed with the axis defined for Altitude mode.




Explore mode: Similar to the explore mode with the mouse; the camera will orbit around a central point, always looking towards it.



Rocket mode: Pressing the assigned button, the camera will move vertically upwards (and back) by the given altitude. Also, the camera is oriented northwards.


Clamp pitch: The maximal camera pitch is clamped depending on the current altitude. If the current altitude of the camera lies between A1 and A2, the maximal pitch interpolated between the specified pitch values.



Timeout: If the joystick is not used for the given amount of time, the rocket mode will end automatically. Also the camera pitch will be set to a value between “Pitch below A1” and “Pitch above A2”, depending on the current altitude.

Each mode is activated with the assigned joystick button. The “Rocket” mode must be deactivated by pressing the assigned button again before another mode can be used. A mode can be disabled by selecting “<disabled>” instead of a button. If a mode should be active without pressing a joystick button, “<no button>” must be assigned to this mode. The number of buttons and axes depend on the joystick hardware.

The joystick modes “Move”, “Altitude” and “Rotate” are similar to the modes available with the “View” navigation mode:

The “Clamp pitch” feature is illustrated below with pitch values φ1 (50°) and φ2 (-50°).
