Ton got them to seed a dozen or so devices to blender coders/artists but I don’t think anyone has really started working on proper blender integration yet.
The main problem is the licence AFAICT isn’t gpl compatible which means it isn’t possible to link with the leap library and without it the thing is just a fancy paperweight. I’ve heard there’s a demo for the BGE floating around somewhere but haven’t tried it out yet.
The secondary problem is I still don’t see any real use case for the thing even after playing around with the demo apps it comes with – considering how much people whine…er, are concerned with performance for things like sculpting and viewport performance having to go through python to get tracking data would simply be unacceptable for anything but a toy demo.
And linux support is still kind of buggy/incomplete which is the main reason I personally haven’t attempted to do anything with it yet – is it a leap bug, a blender bug, a bug in my code, who knows?
If/when the license thing is ironed out I have been working on some python bindings for the thing that could be plopped right into blender with a minimum of fuss and have a fairly good idea on how it could be integrated into the GHOST event system, we’ll see…
