Movement in the Walk and Fly modes are similar except that in Walk mode,
the movement is affected by gravity and the avatar follows the ground.
Turning to the sides is accomplished with either the left mouse button or
the left and right arrows. Forward and backward motion is by the mouse wheel
or the up and down arrows. The motion continues until the key or mouse button
is released.
For all navigation modes, the PgUp key moves the viewer to the previous
viewpoint, and the PgDn key moves the viewer to the next viewpoint.
Also the Home key moves to the first viewpoint, and the End key moves
to the last viewpoint.
Examine Mode
In Examine mode the object being viewed is rotated. It is rotated to the left
and right by either the left mouse button or the left and right arrow keys.
Similarly the object is rotated upwards and downwards by either the left
mouse button or the up and down keys.
In this mode, forward and backward motion is by either the mouse wheel or
the 'a' and 'z' keys.
Box
Use the picture at the left to test the Examine mode rotation. Press the left button
of the mouse near the center of the picture and drag it to the right. As the mouse
is moved further to the right, the speed of rotation increases. Now drag the mouse
slowly left back to the center. The rotation will slow and eventually stop. Dragging
further to the left changes the direction of rotation, and finally lifting the left mouse
button ends the rotation.
Menu
The Viewer menu can be accessed by clicking with the right mouse button.
This menu can be used to change various settings, such as navigation mode.
In particular, the Movement Reset item is used to return to the starting position.
