Graphical projection Perspective projection is a linear projection where three dimensional objects are projected on a "picture plane". This has the effect that distant objects appear smaller than nearer objects. It also means that lines which are parallel in nature (that is, meet at the point at infinity) appear to intersect in the projected image, for example if railways are pictured with perspective projection, they appear to converge towards a single point, called vanishing point. Photographic lenses and the human eye work in the same way, therefore perspective projection looks most realistic. Perspective projection is usually categorized into "one-point", "two-point" and "three-point
No Line on the Horizon to the halfway point. "Moment of Surrender" closed every show. U2 made minor changes to the setlists for the second leg of the tour. "No Line on the Horizon" was performed later in the concerts, while "Unknown Caller" was dropped for several weeks before being revived towards the end of the leg. The band did not play "Stand Up Comedy", "Fez – Being Born", "White as Snow", or "Cedars of Lebanon" at any point in 2009. The 25 October 2009 concert at the Rose Bowl in Pasadena, California, U2's penultimate concert of 2009, was filmed and streamed live over YouTube.
