Three dimensional expression elements in plastic art

It is observed that, designing object forms, which are in real world (on planes, surfaces), in paintings, sculpture, architecture and in plastic art, visual perception is aimed. The survey about "Three Dimensional Expression Elements in Plastic Art" is prepared in three parts. In part one, the topic is studied from the point of theoritical view. In the second part, "expression elements in plastic art" are mentioned, according to the theory. In third part, art evolved throghout the history is examined, under the topics; "art objects in three dimensional expressions", used by artist in artistic methods. In this survey, first of all, object's absolute perceptual psychology in visual perception and - defining- in plastic arts is mentioned. While discovering the third dimension of the objects on The Earth, our perception driven by our senses plays an active role. The cognitive system is resolved by physicologically and physilogically. These physicological and physilogical impacts of dot, line, tissue, light, color, surface, location, depth, mobility and contrast profiles on art objects are determined and proven. World intrisincly keeps evolving. Like industrial and technological breaktroughs after wars, changing life conditions, science and art has also evolved as socio-cultural life -has been changed- parallelly. In this change, the process of formation of the object of art, its use, and its view on the object of art are evaluated. With this survey, object which basically exists in esthetic description yesterday and today in terms of art, in existing objects world, was questioned onthologically. The function of the art, the language of the art, the effects of three dimensional expression method are explained to art object with examples by paying attention to its formation.
