Principles of Three-Dimensional Computer Design for Understanding Impossible Figures

For a better understanding of the impossible figures, it is advisable to use modern technological means by which the design of the geometry of the models gives a complete understanding of how they are made. Computer-aided 3D design completely solves this problem. That is, on the one hand, the ultimate visual variant of impossible figures is created, on the other hand, there is the possibility for real manipulation, movement, rotation and other models of space. In this study, 3D models of impossible figures are fully constructed, which are applied in the educational process in order to develop logical thinking. The steps of creating 3D geometry using open source software Blender 3D are described in details

Computer parametric designing in Blender software for creating 3D paper models

In the contemporary conditions, the implementation of computer parametric design to facilitate the design of 3D paper models is successfully realized using modern technological tools such as the free software Blender. Through the convenient interface of the program, the modeling of the desired three-dimensional shapes is greatly facilitated. This also applies to the automated process of constructing a drawing of the resulting polygonal 3D models, which in the future are assembled into three-dimensional paper models. This paper describes in detail the process of fine-designing 3D paper models using specific exemplary primitive, text, and with relatively complex form.In the contemporary conditions, the implementation of computer parametric design to facilitate the design of 3D paper models is successfully realized using modern technological tools such as the free software Blender.

Principle of work in the process of digitization and reconstruction of model of belt buckle by photogrammetry and 3D computer design

Българската женска народна носия е богата на множество символи, елементи и детайли. Един от най-характерните са пафтите – елемент от колана. Освен като символика със специално преднаначение, пафтите със своята уникална идентичност принадлежат към национално – историческото наследство на България. В настоящото изследване е дигитализиран и реконструиран модел на пафта, притежаващ изящество и красота. Реализацията на завършения тримерен компютърен модел преминава през етапи на фотограметрия и компютърен дизайн със специални скулптуриращи инструменти.Bulgarian female folk costume is rich in multiple characters, elements and details. One of the most characteristic is the belt buckles. As well as specially designed symbolism, the belt buckle - with their unique identity belong to the national - historical heritage of Bulgaria. In the present study a model of a belt buckle is digitized and reconstructed, and possessing grace and beauty. The realization of the completed three-dimensional computer model goes through stages of photogrammetry and computer design with special sculpting tools

Application of modern technological means in the process of digitization of models of national and historical value

България е известна с богатата си история още от древни времена. В рамките на сегашната си територия, страната обхваща най-различни култури, които носят своята характерна специфика и идентичност. Настоящото изследване  цели дигитализацията на модели с национална и историческа стойност, като се прилагат съвременни технологични средства. За осъществяване на целта се използва методичен процес, оптимизиращ взаимодействието на различните работни етапи.Bulgaria has been known for its rich history since ancient times. Within its current territory, the country encompasses a variety of cultures that bear their specific specificity and identity. The present study aims at the digitization of models of national and historical value, applying modern technological means. To achieve the goal, a methodical process is used to optimize the interaction of the different working steps

Life in the AI era - First result of the Erasmus+ HEDY project

HEDY - Life in the AI era is a 2-year Erasmus+ project started in November 2021 targeting higher education audience. Its goal is to offer a comprehensive and shared view of how Artificial Intelligence (AI) is affecting our lives and reshaping our socioeconomic, cultural, and human environments and to define which topics related to AI are of interest to different university studies and how they should be addressed. Four specific free and accessible sources of information will be produced to reach these goals, the first of which is the Booklet, the subject of this paper. The Booklet is an essay defining the HEDY position on life in the AI era and its aim is to identify the challenges, opportunities and expected impact of AI on four different areas: business, governance, skills & competencies, and people & lifestyle. In this paper, we summarise the content of the Booklet. In particular, we describe our methodology to build our rationales based on collecting information from two sources: i) Literature survey, and ii) Focus groups. These two sources provide a unique contribution on AI panorama by combining state of the art research with first-hand opinions and debated questions, concerns, and ideas of interacting individuals. The main finding is that there is the necessity to train citizens in AI by providing teachings, courses and trainings in schools and higher education institutes to facilitate the use and adoption of AI for young people and future generations

Digitalization of Ancient Sculpting Models and 3D Design Using Photogrammetry Methodology

The digitization of ancient sculptures is particularly relevant and necessary in relation to the preservation of the cultural heritage. And the studied ancient models have their unique identity in terms of their visual and functional qualities. In parallel, the study aims to optimize the technological process related to photogrammetric measurements and calculations, technological tools and specialized software applications such as Autodesk ReCap, Blender and MeshMixer. The used models in the article are for re-presentation of popular ancient models & artifacts from city of Varna (by the ancient name Odessos). By using a 3D print device, one of the resulting digitized models of an ancient angel will materialize by applying specific techniques to redesign its geometry. The completed 3D printed item of re-designed model of ancient stone angel is only for personal and non-comercial use. One of the main point in the article is to show advanced computer techniques for teaching and studying. The information in this article has been built for helping other specialist working in digital field regarding photogrammetry. Also the material can be useful for designers, engineers, archaeologists and others in their work for the publicity of ancient treasures
