automatically. If you want the object movie to play faster than the rate you specified in
Frame Duration, type a number greater than 1. To have it play slower, type a number
between 0 and 1. You may need to experiment with different values to get the desired

Scaleable
m Enable Translation—Select to allow the user to move a zoomed-in object within the
playback window.
m Angle of View and Minimum AOV—Enter values for the angle of view and minimum angle
of view. The amount the user can zoom is determined by the scaling factor. The scaling

m Object—The user presses and holds the mouse button to drag an object. When the
pointer is near the edge of the playback window, the object movie plays automatically.
Select this type for objects that in reality would be small enough for the user to pick up.
m Scene—The controls operate similar to a joystick. The user presses and holds the mouse
button to rotate the object. The user cannot drag the object.
m Drag-only—The user presses and holds the mouse button to drag the object. The user
cannot make the object play automatically.
m Absolute—The user clicks the mouse button at various parts of the object to display
different views of the object. Absolute objects can be viewed in different ways from other
object types. For more information, see “Creating Absolute Objects” later in this chapter.

To set the playback speed for the object, open the Frame Duration pop-up menu and enter a
value for frame duration or for frames per second.
m Frame Duration—The number of one-six-hundredths of a second one frame of the object
movie appears on the screen. When you enter the frame duration, the value for frames
per second is calculated automatically.
m Frames Per Second—When you enter a value for frames per second, the frame duration is
