On this property page the controls can be specified.
Movement Speed specified how fast the camera moves when a key is pressed. The speed is measured in map units per second.
If Free Move is selected, the camera altitude can be freely controlled by the user. The corresponding keys are 'move up' and 'move down'. By default, the camera hovers two map units above the ground.
The keys increase global detail and decrease global detail recalculate the error bounds for the QuadTree algorithm with a new value for C. This step may take some time on slow machines, during which the engine freezes. Altering the local level of detail doesn't take any time, as there is no need to recalculate the error bounds.
The 'toggle' keys can be used to set different rendering modes. The shade model switch toggles between flat shading and smooth shading, sometimes referred to as 'Gouraud Shading'. The polygon mode switch specifies whether the scene is rendered using filled polygons or as a wire frame model.
