Tip: Use this behavior to perform a rack-focus effect during a scene.
Parameters in the Inspector
•
Target: An image well to specify the object upon which the camera will focus. Drag an object
from the Layers list into the well.
•
Transition: A slider to set how long it takes for the camera to reach the focus position,
measured as a percentage of the behavior’s duration.
•
Speed: A pop-up menu that sets the type of interpolation used for the movement. The value
can be set to Constant, Ease In, Ease Out, Ease Both, Accelerate, or Decelerate.
The HUD contains the same controls as the Inspector.
Framing
Animates the camera along a path to position it in front of a selected object. You can control
how the object fits into the frame at the ending position, and you can control the shape of the
path to affect the amount of bend or curvature, as well as the apex of such a curved path. Other
parameters allow you to customize the camera’s orientation along the path, the speed at which it
travels, and at what point it begins orienting towards the target object.
The Framing behavior has onscreen controls to allow you to manipulate the path and ending
position in the Canvas. For more information on using the Framing behavior’s onscreen controls,
see
Use Framing behavior onscreen controls on page 937.
Tip: Multiple framing behaviors can be arranged consecutively to move a camera from one
object to another over the course of a scene.
WARNING: Applying a Framing behavior before or after a Basic Motion behavior, such as
Motion Path or Throw, can create unexpected results. These behaviors can continue to affect
the object even after the behavior ends. For example, If a Framing behavior is applied after a
Motion Path, the residual effect of the Motion Path is combined with the path generated by the
Framing behavior, resulting in the target object being framed improperly.
Parameters in the Inspector
•
Target: An image well to specify the object upon which the camera is framed.
•
Target Face: A pop-up menu listing the primary axes: Right (+x), Left (–x), Top (+y), Bottom (–y),
Front (+z), and Back (–z), to specify which face of the target to frame.
•
Up Vector: A pop-up menu providing a constraint for the camera to keep it the right way up.
The pop-up menu offers the following choices: Auto, Target +X, Target –X, Target +Y, Target –Y,
Target +Z, Target –Z, World +X, World –X, World +Y, World –Y, World +Z, World –Z.
Auto tries to guess which axis should be pointing up, and the other choices allow the user to
specify an axis.
•
Framing: A pop-up menu to choose how the target should be framed. The menu choices
include:
•
Fit Horizontally: Positions the camera so the full width of the target fits in the width of
the frame.
•
Fit Vertically: Positions the camera so the full height of the target fits in the height of
the frame.
•
Fit Both: Positions the camera so both width and height of the target fit in the frame.
