Abstract:

The article considers the components of graphic training concept for future mechanical engineers in institutions of higher and vocational education. The definition of «concept» is analyzed in various aspects of application. The essence of «didactic concept» is clarified and pedagogical theories that are embedded in the concept of the developed methodology are identified. It is determined that on the basis of the theory the methodology of learning at university is formed. It is proved that the implementation of this approach in training is based on both purely didactic principles and didactic principles of production training: polytechnic principle, the principle of combining learning with practical activities, the principle of modeling professional activity in the educational process, the principle of professional mobility, the principle of modularity, the principle of self-management in cognitive and production training, the principle of computerization of the pedagogical process, the principle of individuality, the principle of subjectivity, the principle of free choice, the principle of creative realization, the principle of developing potential. Principles of production training have their own characteristics, which are characterized in the article. It is determined that the detailed stage of the concept expresses the specific subject methodology and includes: the goals of teaching engineering graphics by means of computer modeling at the level of engineering and graphic training of future mechanical engineers, at the level of training of engineering and graphic disciplines (in particular, the educational discipline «Descriptive geometry, engineering and computer graphics»), at the level of organization of educational and cognitive subject activities training; didactic principles of structuring the content of engineering and graphic disciplines (including the discipline «Descriptive geometry, engineering and computer graphics»); interactive style of learning engineering graphics by means of computer modeling; criteria, indicators and levels of engineering and graphic training of students as a result of teaching engineering and graphic disciplines.

Abstract:

The article presents the methodology for teaching the theme "Creation and editing of vector graphic information" in basic school, which can be implemented both in full-time education and using distance learning technologies. The methodology is based on the use of the free vector graphic editor LibreOffice Draw and has been tested over several years in teaching vector computer graphics in the seventh grade in informatics course in full-time, as well as in a distance learning format in 2020. The authors substantiate the need to develop universal methods of teaching information technologies that are insensitive to the form of education (full-time or using distance educational technologies) based on the use of free software. Some principles of constructing a methodology for teaching vector graphics based on the new Federal State Educational Standard of Basic General Education are formulated. As the basic operating system used by the teacher, the domestic free operating system "Alt Education 9" is proposed. The article substantiates the choice of the graphic editor LibreOffice Draw as the optimal software tool to support teaching vector graphics in elementary school, formulates the criteria for choosing LibreOffice Draw as a basic tool for studying computer graphics in grades 6–9 for the implementation of distance learning. A universal scheme for the implementation of a distance lesson in teaching information technology based on the use of free cross-platform software, in particular, teaching vector graphics, is proposed.

Abstract:

The article describes the framework of the methodology for teaching basic school students the technology of both processing digital photography and creating raster graphic images from scratch. As a software tool, it is proposed to use the free GIMP raster editor. Raster computer graphics is more complex in relation to vector graphics, since a large number of tools are used in raster graphics, and brush graphic tools (Brush, Pencil, Airbrush) are also actively used, the effective use of which requires user of basic artistic skills. The choice of the free graphic editor GIMP is due to a number of significant advantages of this software tool over analogues. These include the GNU GPL license for its use, cross-platform, relatively low system requirements, functionality close to professional raster editors, as well as a significant stack of educational and methodological literature on the technology of using GIMP in the educational process, that is generally not typical for free software. The complex user interface of the GIMP editor is due to the large number of tools and the full functionality of this software and can be mastered by basic school students, provided that an effective methodology for teaching raster graphics is used in the educational process. When creating a framework for teaching schoolchildren about raster graphics, the technology for using all groups of GIMP editor tools is demonstrated in the process of conducting practical work aimed at creating various raster graphics, the complexity of which gradually increases in proportion to the number of tools mastered by students. Also, the proposed teaching methodology takes into account all the main structural elements of professional raster graphics, namely: the technology for the effective use of the group of operations for selecting image fragments, the technology for the effective use of the group for the transformation operation, the technology for the effective use of the group of drawing tools, image layers, color channels, contours, built-in filters, creation of text elements, creation of GIF-animation.

Abstract:

Vector graphics and 3D modeling have opened up a wide range of perspectives for designers to create various art objects. The use of computer graphics greatly simplified the process of sketch creating, as it provided the ability to change, add colors, and edit entire groups of objects. 3D modeling made it possible to recreate products, taking into account the smallest details in a virtual environment, compose an interior, and perform animation of various processes. The research object is the computer programs Corel Draw and 3D max and their importance for the methodology of development and creation of art objects. As a result of the study, it was found that vector graphics and 3D modeling programs not only made it easier for designers to create art objects, but also made it possible to improve the level of design by changing the usual perception. According to the authors, software products influenced the development of design, which made it possible to create any objects in a virtual environment.

Abstract:

A Computer Graphic Model (CGM) was realized on a personal computer for the purpose of river water pollution simulation and planning. With the aid of common software AutoCAD, a color map of a complex river system was established and a suite of graphic symbol blocks such as pollution source, water intake, wastewater treatment plant etc. was designed to fit the needs of basin pollution management and planning. A person can insert, move/remove or modify these symbol blocks in the CGM of the river basin freely. While a new idea is confirmed, a simulation program POLSIM (written with AutoLISP) can be started which redraws the river with different width and color by the mean flow quantity and water quality. The result of a case study and a group of photographs is presented. The methodology of CGM makes the planning process of basin water pollution control easier, visual and interactive. CGM is a friendly tool to link the decision maker, planner and system analyst with active graphics.

Abstract:

Purpose The purpose of this paper is to establish a cyber physical environment for digital product design and manufacturing. To realize this goal, the specific issue of integrating design knowledge-based system (KBS) and 3D printing (3DP) system is focused. A graphics generation method is thereby developed to transform the KBS outputs into graphical format which can be directly read and manufactured by 3DP system. Design/methodology/approach A graphics generation method is proposed in this paper.

Abstract:

The paper investigates the efficiency of algorithms for solving computational mathematics problems that use a multilevel model of parallel computing on heterogeneous computer systems. A methodology for estimating the acceleration of algorithms for computers using a multilevel model of parallel computing is proposed. As an example, the parallel algorithm of the iteration method on a subspace for solving the generalized algebraic problem of eigenvalues of symmetric positive definite matrices of sparse structure is considered. For the presented algorithms, estimates of acceleration coefficients and efficiency were obtained on computers of hybrid architecture using graphics accelerators, on multi-core computers with shared memory and multi-node computers of MIMD-architecture.

Abstract:

3D computer graphics is information technology that is not mandatory for studying at the level of basic general education. Its study is more related to pre-profile training in advanced programs used in such educational projects as the Mathematical Vertical. In this regard, there is a certain shortage of teaching methods for this topic, using Russian free or open source software as software tools.As the best software to support the teaching of the topic "3D computer graphics", it is proposed to consider both the domestic free 3D modeling system KOMPAS-3D LT V12 for non-commercial and educational purposes, and the free 3D parametric modeling system FreeCAD. The choice of KOMPAS-3D LT V12 is primarily due to the need to use domestic software in the face of constant tightening of economic sanctions against the Russian Federation by a number of unfriendly Western states. These sanctions also have a negative impact on the information infrastructure of Russian educational institutions.The author's method of teaching the topic "3D computer graphics" in basic school has the following characteristic features: it can be used both for distance learning and for full-time education; is based on domestic software, in connection with which the infrastructure of Russian educational organizations does not fall under the threat of an unmotivated refusal of licenses to use foreign proprietary software. In addition, the use of free versions of software in the educational process optimizes government spending on education.

Abstract:

Due to varied personal, social, or even cultural situations, people sometimes conceal or mask their true emotions. These suppressed emotions can be expressed in a very subtle way by brief movements called microexpressions. We investigate human subjects' perception of hidden emotions in virtual faces, inspired by recent psychological experiments. We created animations with virtual faces showing some facial expressions and inserted brief secondary expressions in some sequences, in order to try to convey a subtle second emotion in the character. Our evaluation methodology consists of two sets of experiments, with three different sets of questions. The first experiment verifies that the accuracy and concordance of the participant's responses with synthetic faces matches the empirical results done with photos of real people in the paper by X.-b. Shen, Q. Wu, and X.-l. Fu, 2012, “Effects of the duration of expressions on the recognition of microexpressions,” Journal of Zhejiang University Science B, 13(3), 221–230. The second experiment verifies whether participants could perceive and identify primary and secondary emotions in virtual faces. The third experiment tries to evaluate the participant's perception of realism, deceit, and valence of the emotions. Our results show that most of the participants recognized the foreground (macro) emotion and most of the time they perceived the presence of the second (micro) emotion in the animations, although they did not identify it correctly in some samples. This experiment exposes the benefits of conveying microexpressions in computer graphics characters, as they may visually enhance a character's emotional depth through subliminal microexpression cues, and consequently increase the perceived social complexity and believability.

Abstract:

Computer gaming is a key component of the rapidly growing entertainment industry. Computer games are a multi-billion pound worldwide part of the entertainment industry. However, they are a relatively new type of software product and as such the manner in which they are designed and developed is still evolving. Computer games can be highly complex software systems that involve the expertise of a wide range of professionals ranging from programmers to animators, artists and musicians. When designing computer games, new game concepts can be difficult to communicate. In addition, the creative process could be benefited if game design ideas were capable of being shared widely and discussed. In this paper, we are to some extent shifting the focus from real world situation to what we shall term game world situation. That is, a logically simulated environment is created by defining situations and events based on the hierarchy structure of the situation. Our study defines event type, causality events and event normalization, and aims to develop a logical simulation method. These methods allow us to understand the communication of new game environment design. Specially, the introduction of the definition of events allows us to approach game design in a structural manner rather than by their classification. The proposed method was implemented in the context of changing among natural phenomena in a game environment.

Abstract:

This paper outlines the possibilities of implementing the elements of smart computer graphics (applets and animations) into the curriculum of science-oriented school subjects. Applet is a purposeful (especially educational) program, which was developed on the platform of modern elements of smart computer graphics. These elements allow us to visualize technical and natural objects, phenomena or processes in such a degree of clarity which cannot be achieved by traditional ways of visualisation or by using traditional technological techniques. To be more specific, thanks to computer animations and simulations it is possible to slow down, speed up or shred the processes over time as well as phenomena taking place in natural systems. Moreover, we are able to visualize objects that cannot be seen with the naked eye because of their size (too small or too large), inaccessibility to humans or, in fact, their non-existence. Application components called Interactive Computer Graphics (hypertext, drag and drop, etc.) as well as Flash animations included into the teaching-learning process are together with a comprehensive methodology of their application, a part of newly designed teaching method. The efficiency of this method is verified by pedagogical experiment.

Abstract:

In the shipbuilding industry, it is relatively common knowledge that CAD/CAM (Computer Aided Design/ Computer Aided Manufacturing) systems can generate accurate and consistent drawings. These drawings can then be used for production support lofting, parts generation, reference material and so forth. However, one of the most significant advantages of utilizing a CAD/CAM system is not so commonly known: the development of a design database. While conventional computer systems generate, store and analyze numerical or textual databases or both, CAD/CAM systems generate, store and analyze data bases of graphics. This paper illustrates methods which optimize use of a graphic data base, focusing on the application of CAD/CAM analytical capabilities to mass properties analyses (as practiced in naval ship design). These methods are results of combining CAD/CAM technology with existing systems and knowledge to achieve cost-effective, technically superior, more accurate methods of performing engineering tasks. Accordingly, methodology, actual productivity comparisons and other related applications are presented.

Abstract:

The article presents an innovative methodology for teaching the discipline «Engineering Graphics», aimed at increasing the level of preparedness of students of engineering specialties to perform drawings of parts of complex geometric shapes. Students experience the greatest difficulties when applying dimensions due to the fact that they do not have sufficient knowledge of the production technology of practical experience. The novelty of the technique lies in the application of some provisions of the section of geometry called «Graph Theory». Training maps have been developed that contain algorithms of actions for the stage of applying dimensions to drawings. Particular attention of students is drawn to the knowledge gained in the study of the section of descriptive geometry «Surfaces». As the experience of introducing the new methodology has shown, thanks to the algorithms that organize the sequence of actions of students when applying dimensions to drawings, it is possible not only to help students overcome difficulties in completing an educational task. In addition, since the «Graph Theory» has some elements of the game, it is possible to captivate students with the task. It would not be superfluous to quote the words of the French writer Anatole France (1844-1924): «Only by having fun, they learn.»

Abstract:

Architects and architectural students are exploring new ways of design using Computer Aided Architectural Design software. This exploration is seldom backed up from a design methodological viewpoint. In this paper, a design methodological framework for reflection on innovate design processes by architects that has been used in an educational setting is introduced. The framework leads to highly specific, weak design methods, that clarify the use of the computer in the design process. The framework allows students to grasp new developments, use them in their own design work, and to better reflect on their own position relative to CAAD and architectural design.

Abstract:

Purpose The purpose of this paper is to achieve the acceleration of 3D object transformation using parallel techniques such as multi-core central processing unit (MC CPU) or graphic processing unit (GPU) or even both. Generating 3D animation scenes in computer graphics requires applying a 3D transformation on the vertices of the objects. These transformations consume most of the execution time. Hence, for high-speed graphic systems, acceleration of vertex transform is very much sought for because it requires many matrix operations (need) to be performed in a real time, so the execution time is essential for such processing. Design/methodology/approach In this paper, the acceleration of 3D object transformation is achieved using parallel techniques such as MC CPU or GPU or even both. Multiple geometric transformations are concatenated together at a time in any order in an interactive manner. Findings The performance results are presented for a number of 3D objects with paralleled implementations of the affine transform on the NVIDIA GPU series. The maximum execution time was about 0.508 s to transform 100 million vertices using LabVIEW and 0.096 s using Visual Studio. Other results also showed the significant speed-up compared to CPU, MC CPU and other previous work computations for the same object complexity. Originality/value The high-speed execution of 3D models is essential in many applications such as medical imaging, 3D games and robotics.
