Light field video camera. Basically VR videos that you can move your head positionally in, not just rotate it like the current "360" videos.
how does that even work? i can imagine that being somewhat convincing if you only had 1 eye but if you tilt your head 90° your eyes are arranged vertically. [editline]5th November 2015[/editline] someone explain this trigonometry to me :huh:
Here is an article about it that explains it well:[url]http://uploadvr.com/lytro-immerge-vr-light-field-camera/[/url] [quote]So, what makes Lytro Immerge different? Unlike standard 360º video, light field video captured with Lytro Immerge allows for six degrees of motion freedom within the camera’s volume, which is about one meter. [B]This means that you could conceivably move around within the volume of the sphere and lean in toward objects. In addition to adding a degree of positionally tracked volume to the scene, a true light field recording like Lytro’s creates both horizontal and vertical parallax, giving the scene true depth and perspective regardless of your viewing angle.[/B] We have seen real world light field captures before from OTOY, however those images were still. In contrast, [B]Lytro Immerge is able to capture a full 360º light field in motion at “high cinematic frame rates.”[/B] [B]So how exactly does one do that?[/B] Lytro Immerge uses a [B]modular camera system consisting of “hundreds” of individual cameras in rings, each armed with Lytro’s unique image sensor. These image sensors are where a lot of the magic happens: a light field array of light field cameras, each recording the direction and position of light across a full 360º.[/B] The fidelity of the final image depends on just how many rings of cameras you decide to use and the density of the sensors inside each of them. Higher fidelity can mean higher positional fidelity, so your view is ‘better’ when you’re moving around. It can also mean higher resolution in the headset, “up to 4k per eye” according to Lytro.[/quote]

[QUOTE=Orkel;49053515]Here is an article about it that explains it well:[url]http://uploadvr.com/lytro-immerge-vr-light-field-camera/[/url][/QUOTE] Technology has officially reached the point where I've given up trying to understand it, and instead just choose to be thankful it exists. I guess I gotta ask: using multiple sensor stations, could you fully map out/record an entire scene like that, giving you freedom of movement throughout it with a VR headset? Like, if you pop one in each corner of the room, will you have enough recorded data to turn that video into a full 3D space that you can move through?

Think about light field tech as being a sort of 3D image recording device, where normal cameras are 2D. If you'd want to record a whole room, you have to move the camera through the whole room too to record all possible points of view. Not very storage efficient though. At that point you're better off doing photogrammetry and reconstructing the scene in a 3D renderer.
The 1 metre sphere is the radius that you can move/lean your head in. Adding a camera to each corner just means that you can switch your point of view to the other spheres.
From what I understand, isn't this just photogrammetry with large scenes? Or am I missing a feature
[QUOTE=NixNax123;49054223]From what I understand, isn't this just photogrammetry with large scenes? Or am I missing a feature[/QUOTE] Photogrammetry is reconstructing 3D meshes and textures from multiple photographs. Light field tech is basically a 3D photograph that is sampled based on your eye locations within the 'photo' space.
To sum it up: this camera allows you to move your head [I]inside a movie[/I]. Not CGI or 3D games, but actual film.
Truly this is the future.
I am now excited about VR film.
"Early Oculus Rift sales will be small, just like Palm smartphones" FUCK NO! Gonna be on the ball 24/7 now, why must they do dis.
Wouldn't mind if they started cutting to the chase already. All this talk about the potential, concerns and sales etc and the teasing got tiresome.
[QUOTE=jazzpunk;49055483]Wouldn't mind if they started cutting to the chase already. All this talk about the potential, concerns and sales etc and the teasing got tiresome.[/QUOTE] I'm actually weirded out a little if they really are doing a limited release at first. Years of teasing, releasing devkits, squandering the market advantage they had at first by not releasing anything until they were basically cornered by competitors into releasing, and now they're going to have limited release phases? It just seems strange. There are a lot of people chomping at the bit to get one.
Yeah, whoever's managing their release roadmap... Doesn't seem like the smartest of men.
Wait a minute, Zuckerberg never said they're doing a limited release, only that the initial sales aren't expected to be big! [QUOTE]“The first thing that I wanna stress here is that these new platforms take a long time to develop,” Zuckerberg said during a conference call with investors. “We’ve said that VR and AR could be the next big computing platform, but to put that in perspective, the first smartphones came out in 2003. In that first year, Blackberry and Palm Treo both sold around only a few hundreds of thousands of units. And that’s how we think about [VR].”[/QUOTE] [url]http://venturebeat.com/2015/11/04/zuckerberg-early-oculus-rift-sales-will-be-small-just-like-palm-smartphones/[/url]
They sold 200k devkits alone. Getting a million CV1s sold to consumers doesn't sound too far fetched to me. Friends of friends that tried their friend's DK2 and want one themselves, and all the people that have waited years for the CV1 that decided to skip the DKs.

[QUOTE=Orkel;49053274][url]http://imgur.com/a/u4jYi[/url] Was up for a little bit and then got taken down. It's confirmed legit [img]https://s3.amazonaws.com/lytro-corp-assets/pictures/camera.png[/img][/QUOTE] I've known about light field tech for a while (I have a 1st gen lytro camera), not only would you need a fast server to capture the compressed data, but also something beefy to playback the video in the converted format. Now having this also solves the problem when vr goggles get light field screens, one can focus their eyes on objects that were captured via video then just cgi. Also two things, I hope lytro will come out with a camcorder (which will probably have a high end gpu that can do cuda or opencl), and it will be cool to use this 360 camera for environment mapping.

[QUOTE=jazzpunk;49084731][video=youtube;O-GsBvr0tKk]https://www.youtube.com/watch?v=O-GsBvr0tKk[/video][/QUOTE] Sorry I'm gonna nitpick, but about that shooting gallery bit at the end: red dot sights don't work like that and I'm tired of devs making them that way. The red dot is supposed to be visible only when looking through the sight and in the distance (infinity), so that it makes, you know, aiming actually possible. In ordinary shooters it's kind of excusable to have fakey holosights like those because the weapon will be centered when aiming anyway, but VR allows you to physically aim down sights so it's a disgrace to get a broken fakey red dot sight.

I really want a GearVR and $100 seems p reasonable to me, but I don't have the phone and I can't justify spending that much money to get both. :(
