![]() The company claims an 80% reduction in bandwidth with this projection, with the disadvantage that many more viewports need to be rendered and stored. It was detailed by Facebook on January 21, 2016, mainly aimed at VR video. ![]() The video is rendered in multiple viewports (in Facebook's case 30) where the base of the pyramid contains the full resolution and is right in front of the viewer, while the sides are rendered with a gradually decreasing resolution. The Pyramid projection is a variation of the cubemap using a pyramid geometry. A custom fork of FFmpeg and a tool called max2sphere however do enable. Mainstream video tools have not yet added support for EAC formats, such as GoPro's. This projection was then split horizontally in two streams of 4032x1344 and encoded, which could be decoded by regular UHD decoders. While using a supported Samsung device, simply click View in VR in the top left corner of the video, place the phone in the Gear VR, and experience the photo in an immersive VR environment. They noted that EAC enabled then in using 25% less pixels by packing the equivalent of 5376x2688 pixels into an EAC projection of 4032x2688 pixels. Beyond News Feed, you’ll also be able to explore Facebook 360 photos in virtual reality with the Samsung Gear VR, powered by Oculus. GoPro adopted the EAC format in 2019 when they released the GoPro MAX. In January 2018 the company started using the spherical projection to stream 360 degree videos on YouTube. ![]() It was detailed by Google on March 14, 2017. Explore photos on Flickr in 360° with the Flickr VR app and Samsung Gear VR powered by Oculus. This keeps the density of information consistent, regardless of which direction the viewer is looking. The Equi-Angular Cubemap (EAC) projection is a variant of the cubemap that distributes the pixels evenly by angle. Still, the edges and corners of faces receive more pixels than the center. The image distortion is markedly reduced, especially when looking at the faces head-on. Cube mapping records the environment as the six faces of a cube.
