Why Motion?

Animation Appreciation 101

Why is this so hard?

The Dream:
Animation Everywhere!

What Motion Are we Talking About?
What is a Character?

What are those parameters?
How do we model a human?

Fortunately, we don’t care about details

Abstractions

Abstractions vs. Reality (skeletons vs. humans)

Even the Elbow is complex!

Standard simplified models of humans

Abstraction of Human Motion

Representations of Pose

Rotations…
The animation hacker’s nemesis

Hierarchical Representation

Good Points of Hierarchical Skeletons

Bad Points of Hierarchical

How to Maximize Good / Minimize Bad

How do skeletons differ?

What is a motion (2)

How to represent these functions?

Representation

Representation Matters

Three main ways to make motion

Creating Motion by Hand:
Keyframing

Computing Motion:
Procedural and Simulation

Motion Capture and Performance Animation

Animation from Observation
Not (just) Motion Capture

Motion Capture Technology:
Optical Tracking

Motion Capture Technology:
Video

Motion is tough
 And it’s not just motion capture’s problem
