The Arnold cylindrical camera can operate in two modes. With 'projective' set to off, all rays have a common origin - they are cast from the center of the cylinder. In the vertical direction the camera acts as a pinhole camera, and in the horizontal direction, it acts as a spherical camera. With 'projective' set to on, the camera is more of a true cylindrical camera; in the vertical direction the camera acts as an orthographic view, and in the horizontal direction it acts as a spherical camera.
