Critique: Look at Bouncing Ball Animations

Lecture: Timing



Show Richard Williams DVD

Timing (line with marks)

physics of the real world
action and reaction

Timing gives meaning to motion

Timing tells us the weight of an object, it will help convey a character's thoughts, and emotions, and it can set the mood.

Movement is not important, it is how this movement expresses the cause of the motion.

When thinking about timing you need to:

  • reserve enough to time to prepare the audience for something to happen
  • devote time to the action
  • devote time to the reaction that happens in response to the action

If too MUCH time is spent on any of the above things, the audience's mind will wander
If too LITTLE time is spent, the audience will not get the meaning (or miss the whole thing)

Animation Timing is based on how things move in nature.

Newton's 1st law of motion:
Things do not move unless acted upon by a force.

The force could be:
Natural force (external) such as wind, gravity, friction
an Internal force such as freewill, intention, instinct, mood (the character initiates the action)

There are two different types of timing:
    * timing for inanimate objects
    * timing for living characters

Timing for inanimate objects is based on nature and the physics of the real world.
Timing for living creatures is based on physics and mental operations (intention and emotion). Characters think then act.

Even cartoon motion is based on real motion and timing but it is exaggerated.

To move something, you need to understand the forces that are causing the movement

Things that effect timing:

weight / mass
the construction of an object
the flexibility of an object
the initial force
opposing forces

Things do not move suddenly. They typically accelerate to their maximum speed.
Things do not stop suddenly. Even if they hit a wall, they compress and bounce off a little before stopping.

Timing is based on cause and effect.

Ease in and ease out is really the relationship between velocity and forces.

In-class Exercise:

Part 1. Create an animation using a trajectory chart of a ball moving along a roller coaster. The roller coaster can variate and loop as long as laws of physics apply to the animation.

Part 2. Work on Morph flip-book assignment or Ball Bounce Obstacle assignment.
