一個12KB的Javascript運動引擎：popmotion

一個12KB的Javascript運動引擎。使用動畫，物理和輸入跟蹤。

Flexible

• Native DOM support: CSS, SVG, SVG path and DOM attribute support, out of the box.
• Unlimited: Custom callbacks allow you output to any numerical property or API.
• Power anything: Use with jQuery, Canvas, Three.js, WebSockets, etc.
• Seamless interaction: Tracks velocity for hand-off between input, animation and physics.
• Node support: Run on a server or an Arduino to fuel the IoT.
• Open rAF loop: Run any Process on the core requestAnimationFrame loop.
</ul>

Extendable

Develop your own:

• Easing: Easing functions and bezier curves.
• Physics: Add new physics simulators.
• Input: Create custom Input interfaces for Oculus/Leap/anything.
• Roles: Extend our CSS/SVG/Attr support with routes for Canvas, Three.js, Google Map Symbols or any standardised numerical property.
• Value types: Automatically split special values in child values (ie"#000"->{ Red: 0, Green: 0, Blue: 0, Alpha: 1 }or more complex strings likepathdefinitions.
</ul>

Performant

• Uses and exposes a single requestAnimationFrame thread that automatically winds down when not in use.
• Never reads the DOM, leaving you in total control of performance.
• Over 20% smaller than Velocity.js, 72% smaller than GreenSock TweenMax. Boom shak shakalaka.
</ul>
