There are two popular layouts:Д®quirectangular layout: This is the most widely-used format in computer graphics to represent spherical surfaces in a rectangular form with an aspect ratio of 2:1.

To achieve true 3D in our setup, we went with 6-12 GoPro cameras having 120В° field of view (FOV) arranged in a ring, and an additional camera each on top and bottom, with each one outputting 2.7K at 30 FPS.Д«ecause a 360В° view is a spherical video, the surface of this sphere needs to be projected onto a planar surface in 2D so that video encoders can process it. But this setup of cameras does not support a user tilting their head at 90В°. In traditional 360В° video that is captured using only a single-axis (what we refer as horizontal video), a user can turn their head from left to right. However this required too many cameras вЂ“ instead we use view interpolation in the stitching step to create virtual cameras.ДЄnother important consideration with 360В° video is the number of axes the camera is capturing video with. In initial experiments, we tried capturing 3D video using two cameras side-by-side, for left and right eyes and arranging them in a spherical shape. Though it sounds simple, there is a real challenge in capturing a scene in 3D 360В° as most of the 360В° video cameras offer only 2D 360В° video capture. Such a camera uses either fish-eye lenses or has an array of wide-angle lenses to collectively cover a 360 (Оё) by 180 (П•) sphere as shown below. In order to capture a virtual reality video, you need access to a 360В°-capable video camera. The diagram below shows the end-to-end workflow for streaming 360В°/VR that we built on YahooвЂ™s video platform. During experimentation, we enhanced this same proven platform and set of APIs to build a complete 360В°/VR experience. YahooвЂ™s video platform has a workflow that is used internally to enable streaming to an audience of tens of millions with the click of a few buttons. We also discuss challenges yet to be solved and the opportunities they present in streaming VR. Our experiments and research goes from camera rig setup, to video stitching, to encoding, to the eventual rendering of videos on video players on desktop and VR headsets. In this blog post, we take a look at whatвЂ™s involved in building an end-to-end VR streaming workflow for both Live and Video on Demand (VOD). While this is not an experience that is live in product, it is an area we are actively exploring. The opportunity to produce and stream such content in 360В° VR opens a unique opportunity to Yahoo to offer new types of engagement, and bring the users a sense of depth and visceral presence. Yahoo streams lots of engaging sports, finance, news, and entertainment video content to tens of millions of users. This has been accelerated by the release of new camera capture hardware like GoPro and streaming capabilities such as 360В° video streaming from Facebook and YouTube. When it comes to entertainment and sports, streaming in VR has become the new 4K HEVC/UHD of 2016. With the advent of headgear capable of rendering 3D spatial audio and video, realistic sound and visuals can be virtually reproduced, delivering immersive experiences to consumers. Over the years, significant advancements have been made to bring reality closer to that vision. In that he said, вЂњYou shouldnвЂ™t think of a computer screen as a way to display information, but rather as a window into a virtual world that could eventually look real, sound real, move real, interact real, and feel real.вЂќ

Ivan Sutherland, widely regarded as the father of computer graphics, laid out the vision for virtual reality in his famous speech, вЂњUltimate DisplayвЂќ in 1965. A viewer is вЂњinвЂќ the story, and not on the sidelines as an observer. Unlike a traditional scenario in which a person views a screen in front of them, VR places the user inside an immersive experience. Virtual reality (VR) 360В° videos are the next frontier of how we engage with and consume content. Bringing the Viewer In: The Video Opportunity in Virtual Reality
