Auto-Orientation options
The
auto-orientation options (Layer > Transform >
Auto-Orient) for each layer specify how its orientation depends
on motion paths, points of interest, and cameras.
- Off
- The layer rotates freely, independent of the motion path,
point of interest, or other layers.
- Orient Along Path
- The layer faces in the direction of the motion path. For example,
use this option for a camera to depict the perspective of a driver
who is looking at the road ahead while driving.
- Orient Towards Camera
- The layer is always oriented so that it faces the active camera.
This option is available for 3D layers; this option is not available
for 2D layers, cameras, or lights.
- Orient Towards Point Of Interest
- The camera or light always points at its point of interest.
This option is not available for layers other than cameras and lights.
Note: If
you specify an auto-orientation option for a layer, and then change
its Orientation or X, Y, or Z Rotation properties, the layer orientation
is offset by the new values. For example, you can set a camera with
Orient Along Path, and then rotate the camera 90 degrees to the
right to depict the perspective of a passenger looking out the side
window of a car as it moves.
The automatic
orientation to point to the point of interest occurs before the Rotation
and Orientation transformations are applied. To animate a camera
or light with the Orient Towards Point Of Interest option to look
temporarily away from the point of interest, animate the Rotation
and Orientation transform properties.
