What is Animation?

condition of being alive state of being full of vigor and vivacity giving life or spirit … rapid display of a sequence of images to create an illusion of movement

Bouncing a Ball

1. Path of Action2. Keyframes3. Breakdown Frames 4. Interpolated Frames Four Step Animation Workflow:

1. Path of Action: Arcs

1. Path of Action: Frames

Never evenly space frames

Spacing is always uneven:

2. Keyframes

3. Breakdown Frames

4. Interpolated Frames

Interpolated Frames Keyframe 2 Keyframe 1

Easing In and Out of Keyframes

Interpolated Frames (computer) In-between Frames (drawn)

Lecture Overview What is Animation? Four Step Animation Workflow Squash and Stretch Use all your Degrees of Freedom! FEEL the forces at work

Squash & Stretch

Contact BEFORE not AFTER if you want it to POP…

Similar principle behind cartoon impacts:

Preserve Volume When squashing and stretching.

Return to normal before apex:

SEE and FEEL the core volume:

Retain Volume Volume is redistributed (LOOKS GOOD):

Retain Volume Volume is lost (LOOKS BAD):

Retain Volume Mass is gained (LOOKS BAD):

Retain Volume Volume is redistributed (LOOKS GOOD):

Retain Volume

Lecture Overview What is Animation? Four Step Animation Workflow Squash and Stretch Use all your Degrees of Freedom! FEEL the forces at work

Computational Degrees of Freedom

All digital animation comes from 9 transforms: Translate X,Y,Z Rotate X,Y,Z Scale X,Y,Z Use Every Degree of Freedom

Translate X,Y,Z Rotate X,Y,Z Scale X,Y,Z Use Every Degree of Freedom

Translate X,Y,Z Rotate X,Y,Z Scale X,Y,Z Use Every Degree of Freedom

The most common mistake new animators make neglecting to use all the object’s………. ……………………….Degrees of Freedom.

Lecture Overview What is Animation? Four Step Animation Workflow Squash and Stretch Use all your Degrees of Freedom! FEEL the forces at work

Try to FEEL the forces at work in your moving imagery.

How does the dog’s body FEEL in this moment?

How are the forces FIGHTING over control of its body? Is the dominant force becoming external?

How does a loose equilibrium of forces FEEL in this bird’s body?
