Enviro

Navigation on a virtual terrain

Mouse Navigation - the Standard Terrain Flyer

The drawback to the mouse is that its difficult to move in more than one degree of freedom at a time.  For example, you can turn right, or move down, but not both at the same time.  There are many ways to map the mouse position and mouse buttons to movement.  This is the way Enviro does it:

The further you are from the center of the window, the faster you move. Hold down the left mouse button:     Hold down the right mouse button:     Hold down both mouse buttons:   If you find yourself moving too fast, keep your mouse cursor close to the center of the window, or decrease your Flight Speed with the +/- toolbar buttons, or the 'F'/'S' shortcut keys ("faster / slower")

Mouse Navigation - the Grab/Pivot Flyer

Click and drag the left mouse button on a specific point on the ground to pivot around it.  (Be aware that if you click far from the center of your view, it is possible to undesirably roll the camera.)   Click and drag the right mouse button to grab the ground and move it underneath you.   Hold down both mouse buttons to zoom in or out. Flight Speed does not have an effect on this style of navigation.

Keyboard Navigation

The SHIFT key accelerates all other keys. Same as with mouse navigation, the 'F'/'S' shortcut keys ("faster / slower") can be used to change speed.

Joystick Navigation

Move the joystick: Hold Button 2 and move the joystick: Hold Button 3 and move the joystick: Same as with mouse navigation, the 'F'/'S' shortcut keys ("faster / slower") can be used to change speed.
