Nvidia demos a multi-user VR system at GTC

Thus far, the virtual reality ecosystem has focused almost exclusively on single-user experiences. A few developers have made attempts to use things like HTC's Vive Tracker to bring additional participants without VR headsets into the main user's VR experience. Nvidia has now shown off a proof-of-concept system that uses virtualized hardware to bring four headset-wearing participants into a common VR experience.

The system uses four of Nvidia's Quadro P6000 graphics cards. For those that don't lull themselves to sleep by reciting Quadro model numbers, the P6000 is based on the same GP102 silicon inside the almighty GeForce GTX 1080 Ti and GeForce Titan Xp. The setup uses four of HTC's Vive Business Edition headsets and a single physical machine with four VMs. Thankfully, only one set of Lighthouse tracking beacons are required. No other details were provided, though we imagine the CPU and memory requirements are both "gimme all you got."

Multi-user VR opens up new possibilities for entertainment and productivity software. Nvidia's blog describes possible applications in amusement parks as well as in military and first-responder training. Nvidia's software partners MonsterVR and CAVRNUS are both showing off applications based on the multi-user hardware at GTC.

    I don’t see how this is different to any other multi-VM server.

    It’s a bog-standard VDI server but they’re using the physical ports on the GPUs rather than streaming the data to another device. This is neither original nor something innovative, and if you know how the Vive headsets work (LIDAR) then the fact that you only need one set of tracker beacons is kind of obvious really.

    Four VMs? Why? Isn’t the whole point of this to render one enviroment only with four points of view?

      One VM for each PoV. You could spend you time retrofitting an engine to try and render multiple independent and widely spaced viewpoints with a reasonable degree of efficiency, or you could use two instances of the engine and end up with pretty close to the same overhead for zero effort. Then there are other concerns like now needing to genlock all your HMDs together because they are on the same output clock (otherwise whichever HMD is ‘last’ in the update queue ends up with a latency penalty), having to deal with multiple segregated inputs, etc.

      Basically, making a virtual multiple-networked-boxes-in-a-box removes a massive amount of effort to actually get things working, and suffers minimal performance overhead.

    Roomscale VR, with three other people? Ya’ll be trippin’.

    Have fun with that in your [s<]8' x 8'[/s<] 11' x 11' play area. Lemme guess, the first game supporting this will be VR Twister. [edit] confused Vive with Rift play area.

      Maybe you’re working from (very, pre release) old info, but people have been running far larger spaced with the Rift without issue for quite some time now. 4mx4m to 5mx5m is where things top out depending on PC placement.

    Makes me wanna play those arcade co-op games with a bunch of friends again. Like [url=https://www.youtube.com/watch?v=VgF_VMQ19aA<]X-Men[/url<] or [url=https://www.youtube.com/watch?v=ntqBsj_h4u4<]Dungeons and Dragons[/url<], but this time in VR.

    Sounds like I need to wander over to “VR Village” at some point…

    I could have sworn that GDC was a few months ago.

    GTC maybe?

      Good catch. Corrected from GDC to GTC.

        Too many abbreviations, too little memory to keep track of them all.

    Multi user you say?

    Throw in a little tactile feedback and that could have some… umm… [i<]stimulating[/i<] applications.

      That’s about the time you discover the female avatar across from you is being controlled by some dude from Kentucky.

        Back on the farm they call him “Porky”; dunno why, they just do.

        Why stop with a disturbing image? Now we can be disturbed in multiple senses in higher definition than ever before….

        somehow this connects to Hunter S. Thompson’s “the Kentucky derby is decadent and depraved.”
