Methods building and printing 3D models historical architectural objects

Abstract

The authors present methods building and printing three-dimensional models for graphical reconstruction of historical architectural objects. Procedure sequence of the methods is exemplified through building the model of the Parochial Cathedral of St. Mary of the Perpetual Assistance of the 1950s. After analyzing and assessing the most popular specialized software means, the 3DS Max environment is chosen to build a three-dimensional model. Suggested software tools enable increased accuracy, speed and granularity of fixation of complex systems and expanded databases, providing efficient instruments to deal with bulk data and being relevant to new IT achievements. Sequence and content of operations for analytical and modeling cycles are substantiated. The cathedral model is built on the basis of archive photographs and drafts. The authors describe methods and the algorithm of procedures, principles of architectural and spacious modeling to recreate the architectural object. The three-dimensional model is built by applying a stereogram miniature of the destroyed Cathedral. Reconstruction of spacious configuration of the objects is based on parallax assessment of images. Stages of project implementation are determined. There are described methods of implementing modeling by 3DS Max tools and preparing the model for 3D printing in Cura.

Current trends in the development of pedagogical systems of ukraine in the conditions of digitalization of society

“…Each historical period of society's development is characterized by a basic pedagogical paradigm, which is a set of principles necessary to solve educational problems. Until recently, there was a pedagogical paradigm, which was defined as a paradigm of preparation for life and professional activity [4].…”

“…"The content of ICT education meets modern requirements. "Achieving the set goals can be achieved by providing: educational institutions with technology for creating a digital educational environment and access to broadband Internet; regular training of scientific and pedagogical workers for the development of digital competences, and in the standards of education for pedagogical specialties, provide requirements for the formation of digital competences of graduates; updating ICT curricula and availability of accessible digital content to ensure education[4].It follows from the above that the digitalization of education creates prerequisites for the widespread introduction into pedagogical practice of psychological and pedagogical developments, which allow to intensify the educational process, to implement the ideas of education, including within the framework of new models.Conclusions. Summarizing the analysis of the main trends and features of pedagogicalsystems at the current stage, it is very important to take into account the orientation of global educational processes.…”

The Method of Decomposition of Architectural Objects for the preparation of 3D Virtual Models and Replication

“…The first is the use of various reverse engineering methods, which is not the subject of this work, and the second are manual modelling methods that can also be applied to the reconstruction of objects that no longer exist. In [12] the authors, by using the 3DSMax program, made a virtual model of the Parochial Cathedral of St. Mary of the Perpetual Assistance (Tarnopol, Ukraine), completely destroyed in 1954. This model was linearly scaled using the Cura program and printed on a 3D printer.…”

“…In both works, the authors did not delve into the issues of adapting the D3DMs for printing, did not provide the procedure used, and the obtained prints were characterised by the loss of some architectural elements. The scheme of D3DM generating activities shown in [12] did not concern the problem of modelling the architectural details of the object.…”

Formation of practical skills modeling and printing of three-dimensional objects in the process of professional training of IT specialists

“…So, the need arises to ensure a balance of three components: environment-nature, society, and the economy with the priorities of reasonable, sustainable and comprehensive growth [1]. Under such conditions, vocational education and training are the key prerequisites for achieving sustainable development of society, and also a tool to increase the competitiveness and mobility of the country's labor potential [2].…”
