PERSPECTIVE PROJECTION

Perspective view or projection gives the appearance of an object as it appears to the human eye. It is similar to a photographic picture. In a perspective all the projectors appear to meet at a point e.g. it an observer stands in the railway track, the railway lines appear to meet at a point, even the sleepers seem to be shortening in length as they recede from the eye. If such a view is drawn with the help of drawing instrument ona plane, it is known as a perspective projection.
