Animating scene objects
Wipe or Reveal When the V ISIBLE animated property is enabled, the W IPE and R EVEAL transition
styles introduce the object into the scene by removing a blind from overtop the
object, gradually revealing the object beneath from hidden, to partially visible, then
completely visible.
When the V ISIBLE animated property is disabled, the W IPE and R EVEAL transition
styles removes the object from the scene by using a blind on top to gradually hide
the object beneath from visible, to partially visible, to completely hidden.
Parameters:
•
D IRECTION : Sets the direction of how the blind reveals/hides the object.
Select from: L EFT , R IGHT , U P , or D OWN .
As the following bullets describe, there are slight behavior differences
between the Wipe and Reveal styles’ D
IRECTION settings.
• W IPE : The direction setting represents the direction that the blind is
moving in. When V ISIBLE is enabled, the blind reveals the object behind
it, when V ISIBLE is disabled, the blind hides the object as it moves
across it.
• R EVEAL : When V ISIBLE is enabled, the direction setting represents the
position that the blind starts from, not the direction that it moves toward.
However, when V
ISIBLE is disabled, the direction setting represents the
direction that the blind moves toward.
• F EATHERING : This setting determines the transparency gradient that is applied
to the leading edge of the object as it transitions. Assigning a positive value
allows you to set this parameter as a percentage of the image. For example,
0 results in a zero percent or no gradient, while 1.0 is 100% transparent. Using
a negative value allows you to specify the value in pixels, rather than a
percentage of the object.
• D URATION : The length of time that it will take to complete the transition after it
is initiated at the keyframe. Enter the number or frames, or the amount of time
(00:00:00). The visibility keyframe adjusts its length on the timeline to
represent the duration of the transition.
