Navigate Through Viewpoints
You can navigate through a virtual scene's viewpoints using the menu bar, toolbar,
navigation panel, or keyboard shortcut keys. These navigation methods are inactive if the
author has specified no or only one viewpoint in the virtual world.
• From the menu bar, use the Viewpoints menu to move between viewpoints. Use the
Previous Viewpoint and Next Viewpoint options to sequentially move up and
down the list of existing viewpoints. To move focus to a particular viewpoint, choose a
viewpoint from the list of viewpoints.
• From the toolbar, use the drop-down list of viewpoints to select a particular viewpoint.
• From the navigation panel, use the Previous Viewpoint and Next Viewpoint
controls to sequentially move up and down the list of existing viewpoints.
• From the keyboard, press Page Up and Page Down.
To reset a camera to the initial position of the current viewpoint, use one of the methods
listed in “Reset Viewpoints” on page 7-30. Resetting the viewpoint is useful when you
have been moving about the scene and need to reorient yourself.
This topic illustrates viewpoints using the vrplanets example.
