Ways to Animate
2
• Creating Keyframes
• Path Animation
• Set Driven Keys
• Nonlinear Animation
• Expressions
• Simulations

Keyframe Animation
3
• Keys record attribute changes over time
• The ‘Set Key’ command sets keyframes on all keyable attributes
• You can right-click on channels in the Channel box to keyframe specific attributes
• Auto Key will detect changes in attributes and automatically generate keyframes

Path Animation
4
• Allows you to draw out a path that the object will take through the scene
• Commonly used for vehicles and other objects that animate using routes

Set Driven Keys
5
• Allows you to let the motion of one object drive another
• Used commonly for character rigging, such as making teeth move along a jaw opening

Nonlinear Animation
6
• Uses the Trax Editor to combine animation clips to build animation
• Clips can be trimmed, stretched, cycled, and blended together to create new motions
• Used a lot in character animation

Expressions
7
• Mathematical equations, programming commands, and MEL commands that can precisely control an object’s motion
• Used in rigging and for motion that requires mathematical equations, such as a tire rotating based on the motion of a car

Simulations
8
• Simulates physics to create motion
• Soft and Rigid Body dynamics let you set up initial conditions, apply forces, and then run simulations
• Often used for special effects

Graph Editor
9
• Displays keyframes as curves

Tangent Types
10
Spline Linear Clamped
Flat Stepped Plateau

Character Animation
11
• Character sets collect all the attributes associated with a character in one place
• Character sets allow you to animate characters a pose at a time
![Page 12: Chapter 9: Animation](https://reader035.vdocuments.mx/reader035/viewer/2022062217/5681334e550346895d9a548d/html5/thumbnails/12.jpg)
Trax Editor
12
• Trax is Maya’s nonlinear animation editor
• Stores animation as clips
• Clips can be layered, trimmed, and edited to create new sequences
• Animation used in Trax must be part of a character set
![Page 13: Chapter 9: Animation](https://reader035.vdocuments.mx/reader035/viewer/2022062217/5681334e550346895d9a548d/html5/thumbnails/13.jpg)
Clips and Poses
13
• A clip is a collection of animation curves for a character
• Source clips are added to the character’s scene and are the ‘Master’ copy
• Regular clips are inserted under its character in the Trax editor and can be edits of the source clips
• A Pose is a clip that is only one frame long
