* A OSphereLens is a special nonlinear lens that doesn't correspond to any
|
|
* real physical lenses. It's primarily useful for generating 360-degree
|
|
* wraparound images while avoiding the distortion associated with fisheye
|
|
* images.
|
|
*
|
|
* A OSphereLens is similar to a Cylindrical lens and PSphereLens, except that
|
|
* it is orthographic in the vertical direction.
