What is light field VR?

Much different from the displays used in VR and AR headsets today, light-field displays generate an image that accurately represents how we see light from the real world. Specifically, light-field displays support both vergence and accommodation, the two focus mechanisms of the human visual system.

What is light field display?

Light Field Displays (LFDs) work by chopping up the image volume radially, a bit like a cake. This is unlike volumetric displays, which slices the volume like a loaf of bread. LFDs typically have an angular separation of around one degree between slices.

What is light field data?

The light field is a vector function that describes the amount of light flowing in every direction through every point in space. The space of all possible light rays is given by the five-dimensional plenoptic function, and the magnitude of each ray is given by its radiance.

What is field of view in VR?

In the context of virtual reality (VR), field of view (FOV) is a term that represents how much of the virtual world a learner can see around them at once. With a wide FOV, the learner can see more within their VR experience, likely feeling more immersed.

What is light field rendering?

In the seminal 1996 paper Light Field Rendering, Levoy and Hanrahan describe a representation for light fields that allows for both efficient creation and display. This representation provides a way of generating novel rendered views of a 3-D scene using a 4-D data structure.

Light Field Technology: the Future of VR and 3D Displays

What is a Lytro camera?

The Lytro camera is the first consumer camera that records the entire light field-all the rays of light traveling in every direction through a scene-instead of a flat 2D image. Shoot first, focus later By capturing the light field, you can do incredible things. Like refocus pictures after you take them.

What is the Plenoptic function?

The plenoptic function is the 5-dimensional function representing the intensity or chromacity of the light observed from every position and direction in 3-dimensional space. In image based modelling the aim is to reconstruct the plenoptic function from a set of examples images.

Is 110 FOV good for VR?

FOV in VR Headsets

Some of the best VR headsets, like the HTC Vive Pro and Samsung HMD Odyssey have a FOV of 110 degrees. The Oculus Rift and the lower-priced standalone HMD (head-mounted display, same thing as a headset) Oculus Go have an FOV of about 100 degrees.

Does FOV matter in VR?

Unfortunately, providing a big FOV directly decreases the angular resolution as the available pixels are spread out over the large viewing area. Obviously this is a critical trade-off in HMD design as both visual clarity and FOV are important for great VR.

Which VR has the best field of view?

The HTC Vive Pro 2 might seem like the perfect VR headset on paper, boasting the highest resolution of any headset right now alongside an expansive 120-degree FOV and smooth 120Hz refresh rate, but the execution isn't quite as impressive.

How does light field lab work?

Light Field Lab's technologies combine size, resolution and density to project SolidLight Objects that accurately move, refract and reflect in physical space. The directly emissive modular SolidLight Surfaces form dense converging wavefronts with billions of pixels of photonic resolution.

What happened to the Lytro camera?

Futuristic “light field” camera maker Lytro is shutting down, according to a statement posted online. The company says that starting today, it will stop “taking on new productions and providing professional services,” as it prepares to “wind down” the company over an unspecified period of time.

Is 90 FOV good for VR?

The Oculus Rift has close to a 90 degree FoV which would cover almost 95% of your vision and nearly completely immerse you in the virtual world that you are looking at. While the FoV is great, the Oculus Rift is still a very early prototype and has some issues, the biggest of which is a low resolution.

What is Oculus quest FOV?

According to the hmdq tool the Quest 2's rendered FOV is 104 horizontal and 98 vertical. This is what the headset is rendering, and therefore the maximum FOV available to us.

What is the FOV of the Oculus Quest 2?

But the roughly 90° horizontal field of view of Oculus headsets has not meaningfully changed since the original Rift launched in 2016. In fact, every headset from the company since 2018's Oculus Go, including the current Quest 2, has used the same lens known as Super Libra G.

What is the FOV of the human eye?

In human vision, the FOV is composed of two monocular FOVs, which the brain stitches together to form one binocular FOV. Each individual eye has a horizontal FOV of about 135 degrees and a vertical FOV of just over 180 degrees.

What VR headset has the widest field of view?

XTAL 3 is the most immersive virtual reality headset I've ever worn. Humans beings can, without eye rotation, see roughly 210° horizontally. Just over a decade ago, head mounted displays peaked at around 50° horizontal – any wider starts to introduce geometric distortion.

Who invented Lytro camera?

Ren Ng is the 32-year-old inventor of the Lytro camera, a device he hopes will come to revolutionize the field of digital photography.

When did the Lytro camera come out?

The Lytro company started in 2006 and brought its first consumer-model camera to the market six years later. Despite the impressive tech, the company had struggled recently, as it shifted its attention more to the field of virtual reality and 360-degree image capture.

What is PSVR FOV?

It features an FOV of 100°, 6DOF head-tracking, stereoscopic 3D, and unwarped output to a TV, either for others to view what the headset wearer sees, or a separate display to compete against the headset user using a standard PS4 controller.

What resolution is Oculus Quest 2?

The Quest 2 uses a 1920 x 1832 resolution display for each eye, but because of its lenses, that's not the resolution we actually see (via UploadVR (opens in new tab)).

What did Google do with Lytro?

Lytro, the company that pivoted to enterprise-focused applications of its light-field technology after leaving its commercial camera business, is shutting down after a reported $40M acquisition by Google.
