Principles of Animation for Principles of Animation

The 12 basic principles of animation

1. Squash and stretch - Applying contrasting change of shape
2. Anticipation  - Preparation for the main action
3. Staging -  An action, an expression, or a mood
4. Straight ahead and pose to pose - Two drawing processes. Straight ahead is drawing frame by frame to start to finish. Pose to pose is the action planned out by the animator using a few key frames and then the intervals are filled in.
5. Follow through and overlapping - Follow through refers to the way parts of the body continue to move after the body has stopped. Overlapping describes the offset between timing of the main body and its other parts.
6. Slow in and slow out - How an object need time to accelerate and decelerate as it moves.
7. Arcs - The most economical routes by which a form can move from one position to another.
8. Secondary action  - The action that results directly from another action.
9. Timing - The speed of an action.
10. Exaggeration - Push movement further and add more appeal to an action.
11. Solid drawings - Makes the drawing look 3 dimensional.
12. Appeal -  To create interesting characters visually.
