This project is a WIP of JME3 new animation system called Monkanim. It's under MIT licence, if you want to use it for now do it at your own risk.
Discussion about the design can be found here: https://hub.jmonkeyengine.org/t/monkanim-new-animation-system-in-the-work/36359 Feel free to drop by to state your opinion
Here you can find a small video of the very early development of the project. More will come.

I'd like monkanim to reuse the base classes of JME3 for animation. The source contains a com.jme3.animation package that contains all the classes that needs to be modified on the code base to make the new system work, but also the changes so that the old system still work.
