Abstract
A stereographic panoramic media (SPM) can be received. The media can include a 360 degree field of view (FoV) within the horizontal plane and a usable FoV within the vertical plane. A first, second, and third field of view associated with the SPM can be identified. The first FoV can be 180 degree field of view and the second and third FoVs can encompass 90 degree FoV within the horizontal plane. The SPM can be translated to a cylindrical panoramic media (CPM). The CPM can conforms to a three dimensional hollow cylindrical projection (CP). The first FoV of the SPM can be mapped onto the inner surface of the CP, and the first and the second field of view can be mapped onto the outer surface. The CPM can provide a visible continuous field of view of at least 270 degrees.
