Polubok A. Principles and methods of introducing sculptural plastic in a subject-spatial environment

Thesis for a candidate degree in technical sciences in specialty 05.01.03 – Technical aesthetics. Kyiv National University of Construction and Architecture, Kyiv, 2021. The dissertation is devoted to the improvement of the theoretical base and solving practical problems – research within the technical aesthetics of basic principles and development of methods of organization, interaction of sculptural plastics with design of a subject-spatial environment, as rationally substantiated and practically motivated certain actions, which is the creation of organic and artistic expressive volumetric spatial structure of the subject environment. An analysis and systematization of theoretical and practical material, as well as informative sources of domestic and foreign authors, was carried out. The main existing positions of the interconnection and patterns of perception of sculpture plastics (SP) in an external subject-spatial environment (SE) are outlined. The purpose, task of dissertation work and methods for solving the tasks: bibliographic; structural; analysis, comparison and synthesis; Experimental and natal; composite; Modeling method. The conceptual apparatus of basic terms and contractions is specified. The main existing patterns of interconnection between the SP and SE are revealed: large-scale ratio, methods of placement, environmental formation by joint venture, synthesis of silhouette and detail, perception of expressiveness of sculptural plastic silhouette in SE. On the basis of identified patterns of structural interconnection between sculpture and subject-spatial environment, the principles of introducing sculptural plastics in SE are determined: 1) a large-scale combination; 2) generalization of the SP silhouette; 3) detail of SP; 4) рerception of SP in the types of SE (according to spatial signs). Based on the defined principles, methods are developed and proposed: 1) set the levels of a general large-scale ratio (GSC), adjusting the scale of SE by using the SP; 2) establishing a level of generalization of the SP silhouette; 3) establishment of the level of detail and depth of the relief of the SP; 4) installing the type of SP perception. As a result of systematization and determination of basic principles and methods of composite interconnections of sculptural plastic and subject-spatial environments for practical implementation of SP in SE, as a basis for creating a new or addition to an existing software product, a linear algorithm of a sequence of actions with the possibility of adding and replenishing the combinator bank is developed. Based on a linear algorithm and based on the computer program «Excel» with the use of principles and methods for introducing sculptural plastic in a subject-spatial environment, such as a practical tool and a technical tool for designing sculptures, an interactive algorithm with variable parameters and coefficients with the possibility of replenishing them are developed. and adjustment. The principle of operation of an interactive algorithm based on the computer program «Excel» is mathematical calculations of determining all the following numerical parameters that need to be obtained by introducing initial numerical data. The introduction and implementation of certain principles and developed methods of designing sculptural plastic in a subject-spatial environment with the use of an interactive algorithm on an example of author's creative work has been demonstrated. The practical value of the linear and interactive algorithm has been proved, the effectiveness of the developed methods of implementation and functionality of the algorithmic sequence in the use of an author's technique in the design of sculptural plastic in a subject-spatial environment is confirmed.
