Vibrate Expression
This expression can be used ( Regular Pulse option activated) to cyclically change the size, position and rotation of objects.
On the other hand (option Regular Pulse deactivated), you can add random behavior to the animation. For example, if you are simulating a tracking shot in a car driving over rough terrain, it will look more realistic if the camera randomly moves up and down to simulate the shaking - just as if it were being shaken by the ride.
Incidentally, this expression can be used for all object types - from basic objects to deformation objects, etc.
Example
In the following example, the camera has received a Vibrate Tag that affects the position and orientation of the camera. This creates small camera movements that give the impression of a camera being held in the hand. To ensure that the animation always begins with the same start state, the Vibrate Tag is only activated in frame 1 (the camera has keys for position and rotation in frame 0).
