Facsimile has become heavily reliant upon the JavaFX GUI/3D toolkit. Up to now, we've been using ScalaFX as our JavaFX interface, but we've found some issues with it. As a consequence, we're launching a new project, called sfx, to create a lightweight Scala wrapper for JavaFX for use within Facsimile. As this is a self-contained library, we've decided to launch it as a separate project, which we hope will encourage its use with a wider audience than the simulation community.
If you're interested in participating in sfx, feel free to fork the project on GitHub and submit any pull requests for features you would like to see incorporated.
