Perspective Perspective drawing is a system for creating a two-dimensio nal illusion of a three-dimensional subject or space. Information, whether it's observed or imagined, is translated into a system that allows three-dimensional forms and space to be represented on a two-dimensional surface; creating the appearance of viewing real space on a page. Perspective theory is often separated into two parts, linear perspective, and atmospheric perspective. Linear perspective addresses how the shapes, ed ges and sizes of objects change in appearance when seen at different positions relative to the observer. The distance between the object and the observer, the rotation and elevation of the object, and the viewing angle of the observer are all important in linear perspective . The location of the horizon line, the eye level of the observer, the line of sight of the observer, the location of vanishing points, and the use of trace points and receding lines are key to this practice as we...
