Cylindrical projection

In cylindrical projection, the image is first mapped onto the surface of a cylinder and then the cylinder is unrolled.  It can represent a full 360 degrees horizontally, but cannot represent the full vertical view.  It is the type of image produced by a swing-lens or rotational panoramic camera.  Straight lines are not preserved and the image shows a characteristic “panoramic distortion”.  Some find this appealing and others find it objectionable.
