Abstract (sommario):

The article discusses the problems of teaching students engineering and computer graphics in a single course based on a computer-aided design (CAD) system. Examples of training tasks for acquiring knowledge, skills and abilities in the environment of the drawing and graphic editor of the AutoCAD system are given. They are necessary when performing drawings on engineering graphics, as well as the graphic part of course projects for students of mechanical specialties. Examples of exercises for self-study of the material are considered for a deeper study of the drawing-graphic module structure of the system and the acquisition of skills to work with its tools. The article also discusses several topics for studying the graphical editor AutoCAD, it reveals their contents and provides methods for completing practical tasks. A comprehensive training program extends the ability of teachers to submit material, increases students' interest in graphic disciplines, so it can achieve better results in their development. However, there are a number of problems with this approach. Different levels of basic knowledge of students in the field of computer technology require greater individualization in the organization of the educational process. An additional burden for the teacher is to check the electronic drawings and to control the independence of students' work when performing graphic works using CAD. Combining engineering and computer graphics requires more intensive work from students. It is noted that the implementation of the proposed set of tasks is only the first stage of training students in computer technologies for creating design documentation. The acquired knowledge, skills and working skills in the environment of the AutoCAD system will be in demand when studying modern means of three-dimensional modeling. The execution of drawings using computer tools is undoubtedly more attractive to students, compared to traditional drawing. It is also important to create conditions for actualizing the intellectual potential of students, as well as the formation of positive motivation. Enthusiastic students independently master the functions of the system that are not intended for study by the curriculum. They participate with pleasure in Olympiads in engineering and computer graphics. Ways of improving the verification of graphic works by a teacher are developped. A partial solution to the problem of checking the graphic part of course projects using preliminary drawings in a draft version and intermediate printouts of their electronic versions are proposed.

Abstract (sommario):

This work develops an algorithm for solving computational and graphical work from a cycle of constructive problems of engineering and construction design (construction graphics) using CAD, based on the transition from the traditional method of solving this problem (building a 2D drawing manually) to the method of computer geometric modeling. The application of geometric 3D modeling as a useful CAD tool for solving educational and applied problems is considered. The algorithmization of the solution from the cycle of graphic works on the training course “engineering and computer graphics”, which is the basis for solving problems of engineering and construction design, is shown. A comparison is made between the classical method of solving an engineering problem and using CAD. The use of computer graphic modeling methods using CAD systems facilitates solving the problem, calculating the necessary data, visualizing the results, and contributing to the mastery of universal and professional competencies for students. Their use is expedient in solving applied problems on the training course “engineering and computer graphics” for students of engineering and construction.

Abstract (sommario):

Within the last few years the range of scientific applications for which computer graphics is used has become extremely large. However, not all scientists require the same level of computing power. Until recently the software interface to graphics display systems has been provided by the manufacturers of the hardware. This generated interest in the possibility of using graphics standards. Another important issue is related to the deluge of data generated by super-computers and high-volume data sources which make it impossible for users to have an overall knowledge of either the data structures or the application programs. Partial solutions can be found in emerging products providing an interactive computational environment for scientific visualization. Some of the characteristics required for graphics hardware are presented. From a hardware perspective, graphics computing involves the use of a graphical computer system with sufficient power and functionality that the user can manipulate and interact with displayed objects. To achieve such a level of performance computers are usually designed as networked workstations with access to local graphics capabilities. Finally, it is made clear that the main computer graphics applications are scientific activities. From high energy physics experiments with wireframe event displays up to medical imaging with interactive volume rendering, scientific visualization is not simply displaying data from data intensive sources. Fields of computer graphics like image processing, computer aided design, signal processing and user interfaces provide tools helping researchers to understand and steer scientific computation.

Abstract (sommario):

With the development and application of artificial intelligence, the technical methods of intelligent image processing and graphic design need to be explored to realize the intelligent graphic design based on traditional graphics such as pottery engraving graphics. An optimized method is aimed to be explored to extract the image features from traditional engraving graphics on historical relics and apply them into intelligent graphic design. For this purpose, an image feature extracted model based on convolution operation is proposed. Parametric test and effectiveness research are conducted to evaluate the performance of the proposed model. Theoretical and practical research shows that the image-extracted model has a significant effect on the extraction of image features from traditional engraving graphics because the image brightness processing greatly simplifies the process of image feature extraction, and the convolution operation improves the accuracy. Based on the brightness feature map output from the proposed model, the design algorithm of intelligent feature graphic is presented to create the feature graphics, which can be directly applied to design the intelligent graphical interface. Taking some pottery engraving graphics from the Neolithic Age as an example, we conduct the practice on image feature extraction and feature graphic design, the results of which further verify the effectiveness of the proposed method. This paper provides a theoretical basis for the application of traditional engraving graphics in intelligent graphical interface design for AI products such as smart tourism products, smart museums, and so on.

Abstract (sommario):

This paper presents an efficient implementation of the SCIARA Cellular Automata computational model for simulating lava flows using the Compute Unified Device Architecture (CUDA) interface developed by NVIDIA and carried out on Graphical Processing Units (GPU). GPUs are specifically designated for efficiently processing graphic data sets. However, they are also recently being exploited for achieving excellent computational results for applications non-directly connected with Computer Graphics. The authors show an implementation of SCIARA and present results referred to a Tesla GPU computing processor, a NVIDIA device specifically designed for High Performance Computing, and a Geforce GT 330M commodity graphic card. Their carried out experiments show that significant performance improvements are achieved, over a factor of 100, depending on the problem size and type of performed memory optimization. Experiments have confirmed the effectiveness and validity of adopting graphics hardware as an alternative to expensive hardware solutions, such as cluster or multi-core machines, for the implementation of Cellular Automata models.

Abstract (sommario):

Currently, the field of application of computer graphics is becomingwider. Over the past half century, the computer graphics technology has come a long way from a nascent field to a technology without which not a single area in the modern world can do. The rapid spread has led to research aimed at improving the process ofcreating graphic images. Computer graphics found application in medicine in three-dimensional visualization of computed tomography in the middle of the second half of the twentieth century. Since then, it has become an important part of almost every aspect of the field, from teaching anatomy to helping with diagnosis. However, the specificity of this area and a number of requirements that it imposes have led to the fact that the number of technologies and computer graphics methods used is limited. But despite the limited scope of application, there are still a large number of different implementations of methods used in medicine. Therefore, when developing a new application in the medical field that requires an imaging module, software developers have difficulty choosing the most prefera-ble method to implement. This article analyzes the possibilities of using computer graphics technologies in the field of medicine using the example of lung imaging in the conditions of limited data.

Abstract (sommario):

Object In this study, the authors used preoperative simulation employing 3D computer graphics (interactive computer graphics) to fuse all imaging data for brainstem cavernous malformations. The authors evaluated whether interactive computer graphics or 2D imaging correlated better with the actual operative field, particularly in identifying a developmental venous anomaly (DVA). Methods The study population consisted of 10 patients scheduled for surgical treatment of brainstem cavernous malformations. Data from preoperative imaging (MRI, CT, and 3D rotational angiography) were automatically fused using a normalized mutual information method, and then reconstructed by a hybrid method combining surface rendering and volume rendering methods. With surface rendering, multimodality and multithreshold techniques for 1 tissue were applied. The completed interactive computer graphics were used for simulation of surgical approaches and assumed surgical fields. Preoperative diagnostic rates for a DVA associated with brainstem cavernous malformation were compared between conventional 2D imaging and interactive computer graphics employing receiver operating characteristic (ROC) analysis. Results The time required for reconstruction of 3D images was 3–6 hours for interactive computer graphics. Observation in interactive mode required approximately 15 minutes. Detailed anatomical information for operative procedures, from the craniotomy to microsurgical operations, could be visualized and simulated three-dimensionally as 1 computer graphic using interactive computer graphics. Virtual surgical views were consistent with actual operative views. This technique was very useful for examining various surgical approaches. Mean (± SEM) area under the ROC curve for rate of DVA diagnosis was significantly better for interactive computer graphics (1.000 ± 0.000) than for 2D imaging (0.766 ± 0.091; p < 0.001, Mann-Whitney U-test). Conclusions The authors report a new method for automatic registration of preoperative imaging data from CT, MRI, and 3D rotational angiography for reconstruction into 1 computer graphic. The diagnostic rate of DVA associated with brainstem cavernous malformation was significantly better using interactive computer graphics than with 2D images. Interactive computer graphics was also useful in helping to plan the surgical access corridor.
