perspective. You may think of this value as controlling the focal length of a lens
used to view the images, where a wide angle lens (smaller value) results in a
more pronounced perspective. This value also controls the degree to which
images moved along the Z axis (towards or away from the viewer) change
their apparent size.
◆ HINT: Sometimes, the perspective effect can make it harder to edit the posi-
tion and orientation of images in the Stage window. If so, turn off the
perspective using the Perspective command (see page 136). This command
affects the preview only – not images displayed on screen.
Eye Distance. When displaying images using stereoscopic projection, this
setting controls the amount of left/right image separation that’s applied as a
function of the distance from the zero parallax plane (i.e., the screen).
Depending on the physical size of the screen used to view the presentation, you
may need to adjust this value. For comfortable viewing, the left/right separa-
tion should not exceed 60 mm on screen (approximately 2.4 inches). See “3D/
Stereoscopy” on page 78 for more details.
▲ IMPORTANT: This setting has no effect on stereoscopic video being used in
your presentation, as the eye separation has already been baked into the
video itself. Attempt to keep the amount of physical eye separation of
stereoscopic video within the same limits as other stereoscopic images, as
mentioned above.
EDIT MENU The Edit menu contains commands applying to the current window or currently
selected objects (for example, displays, cues or tween points).
Undo/Redo Reverts recent changes you’ve made to the presentation.
