Road to the Holodeck: Lightfields and Volumetric VR


It's come and gone, but it looked to be very interesting.

What's a lightfield, you ask?

Several technologies are required for VR's holy grail: the fabled holodeck. We already have graphical VR experiences that let us move throughout volumentric spaces, such as video games. And we have photorealistic media that lets us look around a 360 plane from a fixed position (a.k.a. head tracking).
But what about the best of both worlds?
We're talking volumetric spaces in which you can move around, but are also photorealistic. In addition to things like positional tracking and lots of processing horsepower, the heart of this vision is lightfields. They define how photons hit our eyes and render what we see.
Because it's a challenge to capture photorealistic imagery from every possible angle in a given space -- as our eyes do in real reality -- the art of lightfields in VR involves extrapolating many vantage points, once a fixed point is captured. And that requires clever algorithms, processing, and whole lot of data.

What is HDbitT?



What is HDbitT?

A new standard protocol of digital connective, the next generation solution for AV over IP.
HDbitT stand for High-Definition Digital bit Transmission Technology, It’s a new standard protocol of digital connective , specilized in professional Audio/Video over IP delivery and transmission.

HDbitT enables high-definition Audio/Video up to 4Kx2K@60Hz transmit via network cables, optic fiber, power line cable, wireless and even more transmission mediums, it provides more stable performance, better image clarity, further transmission distance and other significant advantages, easily to facilitate the requirement of HD signals long-distance transmission without any converter.

EyeQue Personal Vision Tracker

http://www.eyeque.com/

A series of pixel-powered tests to determine your refraction measurement and generate your EyeGlass Numbers.



The EyeQue Personal Vision Tracker does not provide a prescription.

EyeQue provides users with a refractive tool which, when operated correctly, measures the user’s refractive correction. Results can be used to determine if corrective eyewear would be beneficial. Personal testing does not replace the need for regular eye health exams provided by an eye doctor.
