of view by adding pans or rotate transforms. This is comparable to filming
with a hand-held camera.
■ For a target camera, link both the camera and its target to a
dummy object
on page 2615, then assign the path constraint to the dummy object. This is
comparable to mounting the camera on a tripod on a dolly. It is easier to
manage than having, for example, separate paths for the camera and its
target.
Following a Moving Object
You can use a
LookAt constraint on page 3312 to have the camera automatically
follow a moving object.
■ The LookAt constraint makes the object replace the camera’s target.
If the camera is a target camera, its previous target is ignored.
If the camera is a free camera, it effectively becomes a target camera. While
the LookAt constraint assignment is in effect, the free camera cannot rotate
around its local X and Y axes, and can’t be aimed vertically because of the
up-vector constraint.
■ An alternative is to
link on page 3343 a target camera’s target to the object.
Panning
You can animate the pan of any camera very easily by following these steps:
1 Select the camera.
2 Activate the Camera viewport.
3 Turn on the Auto Key button and advance the time slider to any frame.
4
Use the Pan button (in the viewport navigation tools) and pan.
Orbiting
You can animate the orbiting of any camera very easily by following these
steps:
1 Select the camera.
2 Activate the Camera viewport.
