ABSTRACT
Parallel projections are not only simple to construct, but they also allow for simple reconstructions of common objects. However, if one does not need to take measurements from a projection, it may make sense to take a perspective image, as made by a camera, because of aesthetic reasons or to achieve certain realistic effects, e.g., in computer animation. The first perspective drawings were made about 550 years ago by Italian artists and architects such as Paolo Ucello (1397-1475), who drew the well-known chalice, and Leo Battista Alberti (1404-1472), who drew a true perspective view of Venice.
