SphericalProjector | projector_ |
Warper that maps an image onto the unit sphere located at the origin.
Projects image onto unit sphere with origin at (0, 0, 0) and radius scale, measured in pixels. A 360 panorama would therefore have a resulting width of 2 * scale * PI pixels. Poles are located at (0, -1, 0) and (0, 1, 0) points.
