alan yates (posting as vk2zay on reddit) said the launch rift architecture was identical to the valve room headset architecture with its own tracking implementation and its own fresnel lens system.

>While that is generally true in this case every core feature of both the Rift and Vive HMDs are directly derived from Valve's research program. Oculus has their own CV-based tracking implementation and frensel lens design but the CV1 is otherwise a direct copy of the architecture of the 1080p Steam Sight prototype Valve lent Oculus when we installed a copy of the "Valve Room" at their headquarters. I would call Oculus the first SteamVR licensee, but history will likely record a somewhat different term for it...

Ben Krasnow (former valve employee who now has the youtube channel "Applied Science" https://www.youtube.com/c/AppliedScience/ which you should check out if you haven't yet) posted here on hackernews back in 2017 during the oculus lawsuit.

> It fits a pattern. I was a hardware engineer at Valve during the early VR days, working mostly on Lighthouse and the internal dev headset. There were a few employees who insisted that the Valve VR group give away both hardware and software to Oculus with the hope that they would work together with Valve on VR. The tech was literally given away -- no contract, no license. After the facebook acquisition, these folks presumably received large financial incentives to join facebook, which they did. It was the most questionable thing I've seen in my whole career, and was partially caused by Valve's flat management structure and general lack of oversight. I left shortly after.

and then further down that thread

> Overall, I think Valve is a good place to work, and I learned a lot from all of the incredibly smart people there. The main reason that I left was the difficulty in merging hardware development with the company's exceptionally successful business model. The hardware team was pressured to give away lots of IP that could have been licensed, with the explanation that hardware is just so worthless anyway compared to online software sales, there was no other choice. It's possible that this was a good faith gamble, however it still doesn't preclude the use of business contracts that would have protected our investment. It also isn't so great for morale to hear everyday that your years of work are going to be given away to another company, and then watch that company get acquired for $2B. This is especially the case since many employees strongly voiced concerns about just such a scenario.

Oculus was built on stolen tech taken by employees working at valve who convinced valve to give the tech away in the spirit of cooperation, and then jumped ship to facebook right away for the $$$.

I won't give them a cent.

Every time people post things to do with John Carmack all I can think about is that he was doing the same thing from his former employer to oculus as well. No matter what he did back in the day to make video game engines amazing, his involvement in oculus is a stain on his reputation. Even if you thought he was innocent in a vacuum, along with the rest of the shenanigans with oculus I don't think it was so innocent. He took the source code he wrote, sent it to himself, then he was involved in the "clean room" reimplementation? I don't believe it no matter what the courts ruled could be proven.

They are literally a company founded on "semi legal" theft, fraud, betrayal, etc.
