Anamorphic Perspective

Anamorphic perspective, also known as anamorphosis or trick perspective, involves extreme perspectival distortions which appear undistorted when viewed from a particular viewpoint. Anamorphic effects are produced using linear perspective when the viewer is too close to the picture plane and the object is also nearby. Alternatively these effects can be caused by projecting the image onto other surfaces such as cones (conic perspective), cylinders (cylindrical perspective) or spheres (spherical perspective). Strictly speaking anamorphic perspective is not an independent method. It uses linear, conic, cylindrical and spherical perspective under special conditions. There were mediaeval precedents for these procedures, which we class as proto-anamorphic perspective.
