Perceptographic code in visual culture

Leonid Tchertov

Abstract.

Visual culture can be considered from semiotic point of view as a system of visual codes. Several of them have natural routs. So the perceptual code is formed already on biological level mediating translation of sensory  data into perceptual images of the spatial world. The means of natural perceptual code are transformed in culture, where they are involved in communication by depictions. The depiction on the flat performs the function of a “perceptogram”, which, on one hand, is an external record of an internal perceptual image or an idea, and, on the other hand, serves as a program for a spectator’s visual perception. The means of this “perceptography” form an artificial code, which is, on the contrary to the perceptual code, communicative, deliberately used and transformed in various ways at different periods of time in diverse kinds of practical and artistic activity. Not all perceptograms become pieces of art, but all history of pictorial arts can be considered as a process of development and mastering with the different versions of this perceptographic code. The changes of this code in visual culture are connected with the intrinsic development of “vision forms” as well with invention of external means of communication.

Evolutionary Visual Art and Design

Summary.

This chapter presents an introduction to the different artistic design domains that make use of interactive evolutionary design approaches, the techniques they use, and many of the challenges arising. After a brief introduction to concepts and terminology common to most artificial genetic design, there is a survey of artistic evolutionary systems and related research for evolving images and forms. While the focus is primarily on purely aesthetic fitness landscapes, the survey also ventures into areas such as product design and architecture. The overview shifts from technique to application as organizational strategies, as appropriate. After briefly

surveying additional information sources, the chapter concludes with a discussion of major topics of relevance to evolutionary system designers, providing context for the following chapters. It is hoped that this snapshot of the state of the field will increase exposure to projects and issues, discussion amongst participants, and ultimately the accessibility of these techniques and approaches.
