Everyone is talking about VR GPU manufacturers to do what

On Wednesday (January 13), several waves of technology journalist to arrive in a hotel room near the international trade, the Oculus Rift and experience the latest HTC Vive equipment. Event organizers are not the companies, but a graphics chip maker Nvidia. People familiar with VR knows that this epoch-making technology, demand for graphics computing power has been an order of magnitude. At the upper reaches of the chain of the graphics chip maker, on the VR technology to do what? Ted Baker phone cover

First of all, according to the data provided by Nvidia, "immersive VR experience on performance requirements are the General Gaming PC 7 with. "PC game 1080p 30FPS refresh rate and resolution for technical data, while the VR game's actual rendering resolution 1512x1680x2, refresh rate to arrive at 90FPS, will provide a good experience. Otherwise, cannot be guaranteed when moving picture sharpness and picture detail. Secondly, immersive VR experience delay time must be guaranteed, the user head movement to see the feedback time, should less than 20ms. Otherwise, the human brain can occur due to inability to calculate disorders, symptoms are dizziness, lightheadedness, dizziness.

Nvidia Gameworks VR development platform, offers 5 types of graphics rendering technology, namely: Multi-res shading (Multiresolution color), VR SLI (graphics rendering), Context priority (priority context), Direct mode (direct mode) and the Front buffer rendering (buffer before rendering). Next, let me under the science in simple language, and by the time the next time you're talking about VR, but also seems to understand better.

Multi-res shading

The basic principle of this technology is that optical distortion of the graphics rendering and VR helmets together. VR helmet close to the eye, so lens is needed to help the user focus. Because there are lenses, can cause picture distortion, so the picture needs to be compensated.

Distortion compensation of image information required, screen less than that GPU rendering (part lens optical losses, while the human eye to see more clearly the vision Center than at the edges). So the GPU essentially did a lot of wasted effort. Multi-res shading you want to do is, every frame of the screen into multiple parts, retaining more detail and edge retention in less detail. Another way is to compress images, so as to enhance the rendering speed. Ted Baker phone cover

VR SLI

Graphics rendering technology principle is very simple, is to support two GPU rendering at left and right eye images.

Context Priority

Context priority is not very well understood. For example, if you turn too fast, new pictures have not rendered, or there is a location picture before, it will cause discomfort. How to solve this problem? Technical experts think a way to artificially insert a frame placeholder that is calculated according to the location. GPU need a separate thread to do the work, and stronger before the next frame appears, thereby reducing the picture delay (or jitter caused by frame).

Direct mode

Direct mode requires Windows operating system support. What it means is that when the VR helmet is connected to your computer before, the computer will not recognize it as an extension monitor and Direct mode can let the computer recognize the VR helmet into a new special display device. The benefits below.

Front buffer rendering

Principle related to direct mode is buffer before rendering. If your computer as normal VR helmet display case, you need to be using a standard two-level buffering mode rendering; identify a VR helmet, you can cross the Back Buffer directly to the Front Buffer, reducing delays.

Another similar programme called LiquidVR GPU maker AMD, also has the technical, but in the high-end GPU market share in recent years leading Nvidia.

"It will give 6 iPad charging at full speed, I still 5 iPad." 2A charging equipment will be more and more, if you already have more than one such device at home, while the pursuit of efficiency and convenience, this 6 monster really worth considering. For me, now there are 4 full speed USB is very happy.

Unmanned aerial vehicles wearable and virtual reality changing media and emerging

Impression in the last one, and receive breaking news via the implanted chips idea sounds more like a scene from a science fiction movie. And now look at this thing, this phenomenon seems to be going to happen. Although available for implantation of the chip still needs several years of research and development in order to truly useful, but several others filled with futuristic technology has been put into use. Has seized the opportunity to prepare for the media industry. hello kitty iPhone cases

Salon Media Group CEO and CTO,Cindy Jeffers has been looking for ways to integrate new technologies into media content collection and distribution process, and how they are using these technologies to attract users, Salon is a set up time is really early, and only online news Web site. Some media have already begun to see a new technology can change the news content of the experience, both creators and consumers of news.

UAV

At the CES held in January this year, the news media observed, Advanced UAV technology is the media an opportunity to usher in change.

Cindy Jeffers through demo 3D Robotics development Iris+ drones, he was immediately inspired by the potential of this industry as a whole. "Follow" option (control the drones follow users) and flight planning function (allows the user to set the shooting mode) brings more opportunities for reporters, it was filmed by reporters focus on the things that are taking place, flying in the sky and not just a camera.

Thanks to its good compatibility with the GoPro, it helps to make journalists and media users easier access to unmanned areas, and now many people have started using GoPro to shoot their own stories. And other similar companies, such as Bebop Drone Parrot launched unmanned by integrated control functions in a mobile application and appears more human.

Therefore, the report is obviously a drone "interesting ideas", but whether or not it is feasible, and whether necessary?

United States Federal Aviation Administration (FAA) recently relaxed the drones use policies, all aimed at commercial use of drones has the possibility to really work. From the use of drones to survey of factory farming, to now to monitor police misconduct during the protest, journalists have started to use these relatively low cost equipment for its news gathering.

Wearable device

From the sky to our wrists, hottest new consumer technologies will change the way users getting news, and news.

Although not the first product in the field of wearable device, but Apple Watch has demonstrated great potential for fast news. As Twitter limits focus social media users to 140 characters to say, Apple Watch on the news media's challenge is to be rendered in the space of 42 mm.

Wearable device is not limited to watches and wrist bands, has been extended to embedded chips and digital contact lenses, and even clothing, but wearable and will not replace the traditional equipment, we will continue to see deeper content on a larger screen.

Virtual reality technology

At the Sundance Film Festival earlier this year, in the development of virtual reality have appeared in the news and entertainment soon.

From a hardware point of view, low-price products, such as Google's device and a Cardboard, and integration of mobile phone Samsung Gear VR, easier to extend this technology, and open virtual reality media experience to a wider audience of potential.

These technologies are no longer science fiction or fantasy, but a real product. Wearable devices, unmanned and virtual reality for us News provides a very natural extension.
