We actually use NVIDIA 3D Vision 2 in 3D simulation environments during planning. It's great but quite hard to keep it working because NVIDIA doesn't support it any more. Our software falls back to analgyph for systems that can't run the 3D Vision and I end up using anaglyph a lot and it's totally fine.

We've experimented with VR a bit but it hasn't caught on yet. We've also been trying a few other 3D display technologies.
