FUSEE now contains a built-in key-frame animation system. Set up a timeline-channel, attach it to any field or property of any object in your application and start animating. Under the hood, we have Xirkit (eXpression Circuit) – a very flexible system allowing to connect arbitrary object properties of different objects to each others at run-time. The whole system is already ported to js, so animations and Xirkit work well in web-builds, too.

The animation system can be found in the Development branch of FUSEE’s source code repository. There’s also a wiki article describing how to setup key-frame animations in your FUSEE application.
