00023 //       Class : OSphereLens
00024 // Description : A OSphereLens is a special nonlinear lens that
00025 //               doesn't correspond to any real physical lenses.  It's
00026 //               primarily useful for generating 360-degree wraparound
00027 //               images while avoiding the distortion associated with
00028 //               fisheye images.
00029 //
00030 //               A OSphereLens is similar to a Cylindrical lens and
00031 //               PSphereLens, except that it is orthographic in the
00032 //               vertical direction.
