Changing the View Position

You can change which object you are viewing through and that object’s position and orientation. This makes light and camera positioning easy. To change the view’s current position and orientation:

Note:  Looking through a location with no xform attribute does not allow you to move the object within the Viewport. To enable transformation of a scene graph location, add a Transform3D node and assign the location to the node’s path parameter.

Note:  In many Linux windows managers, the Alt key is used by default as a mouse modifier key. This can cause problems in 3D applications where Alt is used for camera navigation in 3D environments.

You can use key mapping to assign the mouse modifier to another key, such as the (Super or Meta) key, but the method changes depending on which flavor of Linux you're using. Please refer to the documentation on key mapping for your particular Linux distribution for more information.
