Animation Types Keying Attributes Animation Editors Example Movies


Animation in Maya

Keyframe - set keys to change objects properties over time Path - objects follow a pre-drawn motion path Hierarchy - objects parented with other objects in a predetermined way Solid Body Dynamics - objects react with physics driven motion Blend Shapes - morph targets for keying changes in geometry Expressions - scripted animation in MEL (Maya Embedded Language) Motion Capture - data driven internal structures from real motion Intelligent

Dynamic Motion Synthesis by Endorphin - Artificial Intelligence techniques give ‘smart’ animation based on individual characteristics of an animated sequence


Key Attributes

Objects attributes keyed over time position scale rotation

Virtually any attribute can be keyed and animated All attributes keyed by default - Animate -Set Key better to only key the atttributes to

animate via the Channel Box Editor


Animation Editors

Graph Editor Used to manipulate velocity gradients of keys over time Move keys in respect of time

Trax Editor Compile animation clips - poses - cycles Scale and move clips and poses Import audio sequences in .WAV and .AIFF format Also drag audio clip to Timeline to import

Dope Sheet Arrange clips and keyframes in relation to each other and audio sequences


Animation: Graph Editor


Animation: Trax Editor


Animation: Dope Sheet


Animation and Sound

Sound can change nature and mood of animated scenario Maya supports sound imported to the timeline (Trax Editor) Sound can be added as a post-production activity in Adobe Premiere (PC) or

Adobe After Effects (PC & MAC), Final Cut Pro (MAC)


Setting up a Model to Animate

Group, set and name the component hierarchy Scale model to appropriate size Set pivot points for components to be animated


Importing Geometry into Maya (.3ds de-facto format)


Grouping and naming components in the Hypergraph


Scaled and Positioned


Rotational pivots not set


Move pivot mode - Insert (PC)


Carefully position pivot on rotation axis in each viewport...


Move pivot - Front View


Move pivot - side view


Move pivot - top view


Pivot set - top view close-up


Rotational pivot set


Limiting animation axis


Setting limits on rotational axis


Limits Set and Indicated in Display


Limits Set and Indicated in Display

Apply some textures...


Creating a rotational MEL expression to control the rotor

rotor.rotateY = time * 1000

Selected objects appear as named in the Hypergraph attributes

create / edit


Apply some lighting and textures
