Not exactly. See my comment here: https://news.ycombinator.com/item?id=28871907 https://news.ycombinator.com/item?id=28871907 It's not that valve co-developed the rift, its that CV1 was exactly the steam sight headset with the CV tracking system and new fresnel lenses. Valve employees convinced whoever made decisions over there to just give the tech over to oculus without a license or contract, and then those employees jumped ship to facebook/oculus in one of the most egregious unethical backstabs in recent tech memory. Carmack couldn't convince his employer to give away the work he did, so he just took it with him and somehow was involved in a 'clean room' reimplementation of work he did for someone else. It's part of a pattern of unethical behaviour for the big names in oculus. I wouldn't give them a penny.
