aim

explore possibilities for creating content from the browser, beginning with animation

investigation

  • Interviews
  • Processes of making animation
  • Want to coordinate multiple kinds of content
  • Want to apply animation to existing web content
  • Importance of layered content

Art Animation Creators

  • Want to focus on VR
  • Important to be able to start easily
  • Need to consider different types of animation used throughout the world
  • Want to be able to combine resources
  • Emphasised importance of the time axis
  • Being able to create animations in the browser would be great since anyone could create animations
  • Would like to use animation tools for education

Web Animators

  • Would love to be able to compare animations with a view to consistency
  • In addition to being able to change visual effects like vertex/alpha/color, adjusting delay/duration/easing is even more important
  • The time axis is the primary axis that we tweak
  • We'd like to share the animation
  • It's hard to implement interruption of animations
  • Timeline synchronization including synchronizing with music
  • Tools that anyone can use and on any platform
    • People love their animation tools
    • Tools in the browser can be easily tried
  • Associate with different resources
  • Being able to re-use animations and effects

Animation expression

  • Common animation parameters
    • Basic visual properties: vertex, alpha, color
    • Timing properties: duration, delay, easing
      (In terms of animation, the timing axis is the more important of the two)
  • Interest in VR and 3D

summary

Strong interest in Web/Browser-based animation tools

"As a platform engineer, I want to inspect all the animations and see exactly what they're doing."

"As an app developer, I want to replay the interactions in my app and fine-tune their timing."

      backgroundColor: 'red' },
    { transform: 'translate(-20px)',
      easing: 'ease-out' },
    { backgroundColor: 'blue' },
    { transform: 'translate(100px)',
      backgroundColor: 'green' } ],
  {
    duration: 500,
    iterationStart: 0.5,
    iterations: 2.5,
    easing: 'ease-in',
    direction: 'alternate'
  });

Saving changes

CSS Animations

  • Changes to keyframes
    • Update original @keyframes (i.e. affects all users of rule)
  • Changes to timing graph
    • Updates the winning declaration of each property

CSS Transitions

  • Not possible to change repeat count etc.
  • Updates the winning declarations of each property

Scripted animations

  • Have a button / tab to generate source

Replay?

  • DOM changes (e.g. FLIP method, node removal, display:none etc.)
  • Record and replay mode?

Concept #2:

Unexpected Avars

"As an animator, I want to discover

new animation expressions."

"As an amateur animator, I want to make animations more easily."

Concept #3:

Stateful Animations

"As an app developer, I want to add animated transitions to my app's interactions"

Challenges

  • How to work with interactions that modify the DOM?
  • How to work with existing apps?
  • Save format? CSS? SASS? JSON?
  • Does this even need to be an animation tool, or is animation just part of a bigger state editing tool?
    • Let's you build Web Components / React components?

Concept #4:

Layered Animation

"As a web creator, I want to create web animation content easily"

"As a web creators, I want to reuse web animation / animation's effect"

What is Layered Animation?

Layered Animation ≒ Group of Animation Contents

What is Layer?

Animation Layer consist of Web Animation Contents.

Insert Layered Animation

We can insert web content as "Animation Layer"

Element.appendAnimation("./animatedWebPage.html");
Element.animate("./AnimationEffect.json");

Reuse Layered Animation

We can insert Layered Animation from URL.

And, we can insert Layered Animation effect from JSON file.

Element.appendAnimation("./animatedWebPage.html");
Element.animate("./AnimationEffect.json");

Concept #5:

Design Mode

"As a web developer, I want to make animated components like spinners and highlight effects"

Design mode context

  • A keyframe (limited to a single element)
  • A CSS ruleset
  • A state (cf. Stateful Animations)
  • No context (sets element style?)

Other ideas

  • Animation recommend
  • Built-in physics engine
  • Customize animation for myself
  • Animation Hub (GitHub-like)
    • co-development
    • manage making histories
  • Cut animation (for mobile)
