Google’s newly announced Seurat rendering tech purportedly makes use of ‘floor light-fields’ to show high-quality CGI movie property into detailed virtual environments that may run on cell VR hardware. The corporate gave Seurat to ILMxLab, the immersive leisure division of Industrial Mild and Magic, to see what they might do with it utilizing property instantly from Star Wars.
Google simply announced Seurat this week, a brand new rendering expertise which could be a graphical breakthrough for mobile VR. Right here’s what we find out about the way it works to date:
Google says Seurat makes use of one thing referred to as floor light-fields, a course of which includes taking authentic ultra-high high quality property, defining a viewing space for the participant, then taking a pattern of potential views inside that space to find out all the pieces that presumably could possibly be considered from inside it. The high-quality property are then lowered to a considerably smaller variety of polygons—few sufficient that the scene can run on cell VR hardware—whereas sustaining the look of high high quality property, together with perspective-correct specular lightning.
As a proof of idea, Google teamed with ILMxLab to indicate what Seurat might do. Within the video above, xLab says they took their cinema-quality CGI renders—these which might usually take a very long time to render every particular person body of ultimate film output—and ran them by Seurat to make them capable of playback in real-time on Google’s cell VR hardware. You possibly can see a teaser video heading this text.
“When xLab was approached by Google, they said that they could take our ILM renders and make them run in real-time on the VR phone… turns out it’s true,” mentioned Lewey Geselowitz, Senior UX Engineer at ILM.
Star Wars Seurat Preview
I bought to see the Star Wars Seurat-rendered experience teased within the video above for myself working on a prototype version of Google’s standalone Daydream headset.
Once I placed on the headset I used to be dropped into the identical hangar scene as proven within the video. And whereas there’s no changing the true high high quality ray-traced output that comes from the cinematic rendering course of (that may take hours for every body), this was definitely among the best graphics I’ve ever seen working on cell VR hardware. Along with sharp, extremely detailed fashions, the ground had dynamic specular reflections, evoking the identical type of lightning you’ll anticipate from among the best real-time visuals working on high-end PC headsets.
What’s significantly magic about Seurat is that—in contrast to a easy 360 video render—the scene you’re is really volumetric, and correctly stereoscopic irrespective of the place you look. That implies that while you transfer your head forwards and backwards, you’ll get correct positional monitoring and see parallax, identical to you’d anticipate from high-end desktop VR content material. And since Google’s standalone headset has inside-out monitoring, I used to be actually capable of stroll across the scene in a room-scale sized space with a correctly viewable space that prolonged all the best way from the ground to above my head.
I’ve seen quite a few different light-field approaches working on VR hardware and sometimes the precise viewing space is way smaller, typically only a small field round your head (and while you exit that space the scene is now not rendered appropriately). That’s primarily for 2 causes: the primary of is that it could actually take a very long time to render massive areas, and second is that giant areas create big file sizes which are troublesome to handle and sometimes impractical distribute.
Google says that Seurat scenes, however, end in a lot smaller file sizes than different light-field strategies. So small that the corporate says cell VR experience with many particular person room-scale viewing areas could possibly be distributed in a size that’s just like a typical cell app.
