Thanks all for your ideas and suggestions.

My primary goal is to try and create as real as possible virtual environments where product models can be loaded in one of many use-case scenes. I'd like to try and see if the Vive controllers can be used to interact with the scene elements.

Yes, I've heard of the voxel based Occulus modeler. It looks pretty cool and I'm interested in what Jama will come up with. I haven't had the time lately to don my Rift and check it out-- and I probably won't any time soon as I'm pretty much booked with the Vive project right now. I'll keep folks posted as I figure things out.
