There are four camera-specific behaviors: Dolly, Sweep, Zoom In/Out, and Zoom Layer.
Dolly
Moves the camera a specified distance along the camera’s Z axis.
Parameters in the Inspector
Distance: A slider and value slider that set the distance of the dolly movement.
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.
HUD Controls
The HUD contains the same controls as the Inspector.
Sweep
Pivots the camera across a specified arc.
Parameters in the Inspector
Start: A dial and value slider that set the starting angle of the camera’s orientation
relative to the camera’s current orientation. A nonzero value causes the camera to jump
to this value at the start of the behavior.
End: A dial and value slider that set the final angle of the camera’s orientation relative
to the camera’s Start parameter value.
Speed: A pop-up menu that sets the type of interpolation used for the rotation. The
value can be set to Constant, Ease In, Ease Out, Ease Both, Accelerate, or Decelerate.
Axis: A pop-up menu that sets the axis around which the sweep occurs. Value can be
set to Tilt X, Swivel Y, or Roll Z.
HUD Controls
The HUD contains the same controls as the Inspector.
Zoom In/Out
Animates the camera’s Angle of View parameter.
Parameters in the Inspector
Zoom: A slider and value slider that set a proportional value used to modify the
camera’s Angle of View parameter.
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.
