Default Navigation

By default, no tool is active, and you can navigate the surface using the keyboard and the mouse.

• Keyboard:

  • Arrow Up - move the observer towards the target.

  • Arrow Down - move the observer backwards from the target.

  • Arrow Left - turn left.

  • Arrow Right - turn right.

  • Left Shift + Arrow Left - move the observer to the left.

  • Left Shift + Arrow Right - move the observer to the right.

  • Page Up - look up.

  • Page Down - look down.

  • Home - zoom in.

  • End - zoom out.
     

• Mouse:

  • Double-click - move the observer at the position of the double-click. If the elevation of the observer was lower than the elevation of the terrain at the new position, the observer is elevated to be above the terrain.

  • Right-click - turn the observer to the point of the click.

  • Rotate Mouse Wheel forward - zoom in.

  • Rotate Mouse Wheel backwards - zoom out.

Mouse Navigation Tool

This tool enables more extensive navigation using the mouse:

• Hold the left button and move the mouse to look around.

• Hold the right button and move the mouse to pan the surface.

• Hold the wheel and move the mouse up and down to change the elevation of the observer.

Navigation with arrow keys is active and the same as in Default Navigation mode.

Walk Mode

Use this tool to simulate a walking around the terrain, with the observer always being at a fixed offset from the terrain. You can adjust this offset from the Walk Mode popup windows. The offset cannot be less than 3 elevation units. If the observer is walking too close to the terrain, you can experience transparency of the nearest faces of the terrain.

• Keyboard
  Navigation using the keyboard is the same as in Default Navigation mode, except for zooming (Home and End), which is disabled.
   

• Mouse Navigation:

  • Hold the left button and move the mouse to look around.

  • Rotate mouse wheel to walk forwards or backwards.
