How does 360 / VR Video work?
Multiple cameras are configured in such a way to capture a full 360 degree spherical view using wide angle lenses. These images are then stitched together in software which bends and distorts the overlapping edges to create a 360 degree single image. This image is unwrapped and delivered as a flat “Equirectilinear” video file (like a map of the earth flattened out as a rectangle).
These equirectilinear files can be viewed using various platforms such as Facebook, Youtube, Vimeo and within purpose made websites and manipulated with a mouse to drag and view or by using the gyroscope built into a smartphone.
Content can also be delivered via higher end purpose made systems like the HTC Vive and Oculus headsets.
