Navigate Using Orbisnap

You can navigate around a virtual world using the menu bar, toolbar, navigation panel, mouse, and keyboard.

Navigation Panel — The center navigation wheel and two curved buttons on either side move you about the scene. Experiment by moving backward and forward and side to side until you become comfortable with the controls.

Navigation view — You can change the camera position. From the menu bar, select the Navigation menu Straighten Up option. This option resets the camera so that it points straight ahead.

Navigation methods — Navigation with the mouse depends on the navigation method you select and the navigation zone you are in when you first click and hold down the mouse button. You can set the navigation method using one of the following:

From the menu bar, select the Navigation menu Method option. This option provides three choices, Walk, Examine, or Fly. See the table Orbisnap Mouse Navigation.
From the toolbar, select the drop-down menu that displays the navigation options Walk, Examine, and Fly.
From the navigation panel, click the W, E, or F buttons.
From the keyboard, press Shift+W, Shift+E, or Shift+F.

Navigation zones — You can view the navigation zones for a virtual world through the menu bar or keyboard.

From the menu bar, select the View menu Navigation Zones option. The virtual world changes as the navigation zones are toggled on and appear in the virtual world. Alternatively, from the keyboard, press the F7 key.

The following table summarizes the behavior associated with the movement modes and navigation zones when you use your mouse to navigate through a virtual world. Turn on the navigation zones and experiment by clicking and dragging your mouse in the different zones of a virtual world.

If your virtual world contains sensors, these sensors take precedence over mouse navigation at the sensor location. In this case, mouse navigation is still possible through the right or middle mouse buttons.

Keyboard — You can also use the keyboard to navigate through a virtual world. It can be faster and easier to issue a keyboard command, especially if you want to move the camera repeatedly in a single direction. The following table summarizes the keyboard commands and their associated navigation functions. You do not have to capitalize the letters to perform their intended function.
