Pyramid of vision

The visual pyramid, also called cone of vision, the geometric- optical term in painting which conveys a three-dimensional two-dimensionally in an image space by means of perspective. It serves as an auxiliary structure to the illusion of spatial depth on the screen and is responsible for the creation of such a picture of concern. Lead from the image of (imaginary ) finite - even theoretically infinite - perspective lines on the points, each cross section of the line of sight between the visual axis and the eye forms a visual pyramid. The top of the pyramid is therefore in the eye, and the perspective on the image forms the base with their individual pixels. The maps a visual process.

The Italian Leon Battista Alberti (1404-1472) introduced the term in his treatise De Pictura art theory 1435/1436 in the art of the Renaissance one. The considerations were incorporated into the painting and had an impact not only during the early Renaissance, but also for many centuries thereafter.

According to Jacques Lacan (1901-1981) found in the visual pyramid a " localization of the gaze " or the " systematization of space" instead. The vanishing point should correspond to the eye point; the sitter should be designed so that it is centered on the seeing and is projected to the horizon.
