Hey,
as the SDK matures towards release, I cleaned up some of the dirty corners and the (always dreaded) AWT/OGL threading is now much cleaner, especially in regard to loading scenes. Other things like camera control and update of values in the windows are also much faster because less queueing is needed for the code logic. In tests with the development IDE, normally sized models load up to 5x faster now, theres much less lag when switching camera views or selecting Geometry in the SceneComposerA plugin in the jMonkeyEngine3 SDK, allows editing the content of j3o files which represent a complete scene or model. which is about 10x faster now. Switching between files and/or reloading should also work more smoothly.
All in all the switch is quite severe internally, opening Scenes with the TerrainEditor is still broken atm for example, @Sploreg and me are on it. I am quite happy about the results and how quickly the change was implemented in the end though, this frees up a lot of time for the other planned improvements.
Cheers,
Normen
