Popmotion

Anything in, anywhere out

Popmotion is a 12kb JavaScript motion engine. Make it pop with animation, physics, and input tracking. In the browser, on Node, anywhere.

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.

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 like path definitions.

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.
