Lytro, a number one light-field firm, is positioning its light-field seize and playback know-how as the best format for immersive content material. The firm is constructing a toolset for capturing, rendering, and intermingling each artificial and live-action light-field experiences which might then be delivered on the highest high quality playback supported by every particular person platform.
Speaking with Lytro CEO Jason Rosenthal on the firm’s Silicon Valley workplace, I obtained the rundown of how the corporate goals to deploy its tech toolset to create what he calls the Lytro Reality Experience, immersive experiences saved as light-fields after which delivered for the precise high quality and efficiency capabilities of every consumption finish level—all the best way from the highest-end VR headset at a VR arcade all the way down to cell 360 footage seen by way of a smartphone.
Light-fields are pre-computed scenes which might recreate the view from any level throughout the captured or rendered quantity. In quick, that implies that a light-field may be performed again as scenes which exceed the graphical capabilities of real-time rendering whereas nonetheless retaining immersive 6DOF positional monitoring and (to an extent) interactivity. Though not with out its personal challenges, light-fields intention to mix the perfect of real-time immersion with the visible high quality of pre-rendered VR experiences.
Rosenthal made the purpose that revolutions in media require new content material codecs with new capabilities. He pointed to the PDF, OpenGL, http, and MPEG as examples of media codecs which have drastically altered the best way we make and eat info. Immersive media, Rosenthal says, requires a volumetric format.
To that finish, Lytro has been constructing an entire pipeline for light-fields, together with seize/rendering of light-field content material, mastering, supply, and playback. He says that the good thing about this method is that creators can seize/render and grasp their content material as soon as, after which distribute to headsets and platforms of various capabilities with out having to recapture, recreate, or remaster the content material for every platform, as presently must be performed for many real-time content material spanning desktop and cell VR headsets.
There’s three principal items of Lytro’s toolset that makes all of it potential. First is the corporate’s light-field digital camera, Immerge, which permits high-quality live-action light-field seize; we lately detailed its newest developments right here. Then there’s the corporate’s Volume Tracer software program which renders artificial light-fields from CG content material. And lastly there’s the corporate’s playback software program which goals to allow the highest-fidelity playback on every machine.
For instance, a creator might create a high-fidelity CGI scene like One Morning—a Lytro Reality Experience which the corporate lately revealed—with their favourite industry-standard rendering and animation instruments, after which output that have as a Lytro Reality Experience which may be deployed throughout high-end, low-end, and even 360 video without having to change the supply content material for the precise capabilities of every machine, and with out giving up the graphical high quality of raytraced, pre-rendered content material.
Lytro is protecting its instruments near the chest for now; the corporate is working one on one with choose clients to launch extra Lytro Reality Experiences, and encourages anybody to get in contact.
I’ve seen a variety of the corporate’s newest Lytro Reality Experiences as performed again alongside the spectrum of units (like Hallelujah), from high-end desktops appropriate just for out-of-home VR arcades, all the best way all the way down to 360 playback on an iPad. The concept is to maximise the constancy and expertise to the best diploma that every machine can assist. On the high-end desktop, as seen by way of a VR headset, meaning most high quality imagery generated on the fly from the light-field dataset with 6DOF monitoring. For much less succesful computer systems or cell headsets, the identical scene can be represented as baked-down 3D geometry, whereas cell units would get a top quality 360 video rendered at as much as 10Ok decision—all utilizing the identical pre-rendered supply belongings.

The attraction of the light-field method is actually clear, particularly for creators looking for to make narrative experiences that go above and past what’s potential to be rendered in real-time, even with high of the road hardware.
Since light-fields are pre-rendered nonetheless, they’ll’t be interactive in the identical approach that conventional real-time rendering may be. Rosenthal acknowledges the limitation and says that Lytro is quickly to debut integrations with main sport engines which can make it straightforward to combine and match light-field and real-time content material in a single expertise—a functionality which opens up some very attention-grabbing prospects for the way forward for VR content material.
For the entire attention-grabbing potential of light-fields, one persistent hurdle has hampered their adoption: file sizes. Even small light-field scenes can represent enormous quantities of knowledge, a lot that it turns into difficult to ship experiences to clients with out resorting to huge static file downloads. Lytro is nicely conscious of the problem and has been aggressively engaged on options to scale back knowledge sizes. While Rosenthal says the corporate continues to be engaged on reining in light-field file sizes, the corporate offered Road to VR with a recent have a look at the their present knowledge envelopes for every consumption end-point:
- 0.5TB/minute for 6DoF in-venue
- 2.7GB/minute for in-home desktop
- 2.5GB/minute for pill/cell units
- 9.8MB/minute for 360 omnistereo
The above is all based mostly on the corporate’s Hallelujah expertise, as optimized for every consumption end-point. Think these numbers are scary? They have been a lot increased not that way back. Lytro has additionally teased “attention-grabbing work” nonetheless in growth which it claims will scale back the above figures by some 75%.
Despite Lytro’s imaginative and prescient and rising toolset, and an ongoing effort to battle file sizes into submission, there’s nonetheless no publicly obtainable demo of their know-how that may be seen by way of your individual headset. Fortunately the corporate expects that the primary public Lytro Reality Experience from certainly one of their companions will launch to the general public beginning in Q1 2018.
