The article is devoted to the peculiarities of teaching the discipline "Descriptive geometry" in the conditions of distance learning, it examines the application of information technologies in the educational process in geometric and graphic disciplines. Increasing the speed of information processes, reducing the number of hours for mastering the discipline. the conditions of distance learning set new tasks for teachers and dictate their requirements for teaching graphic disciplines and the use of teaching experience in a new reality; there is a need to introduce and develop new forms of education without losing the quality of education. Geometric-graphic disciplines occupy one of the important places in technical education, the complexity of the study of which lies in the development of a graphical representation of phenomena, objects and processes by methods of constructive geometric modeling. The knowledge and skills acquired by students contribute to the development of spatial, imaginative and rational thinking, which is necessary for future professional activities. Descriptive geometry is a discipline that is not easy to master on your own without a conscious understanding of the logic and sequence of geometric constructions, without deep knowledge of theoretical foundations and constant, repeated implementation of practical tasks. The acquisition of practical skills in mastering the methods of discipline has become more difficult in the current epidemiological situation. In modern conditions of distance learning, the use of the Simplex geometric modeling system made it possible to develop and propose a new concept of geometric-graphic interaction, which significantly reduced the time for completing and checking educational tasks in real time. The proposed technology reveals the deep informational essence of the studied discipline "Descriptive Geometry" and becomes a powerful research tool for students. The integration of traditional teaching methods in the graphic preparation of students with computer and communication facilities increases the possibilities of communication and improves the quality of teaching.

Two geometric-graphic Olympiads are held in St. Petersburg: the urban Olympiad in descriptive geometry, initiated by BSTU “VOENMECH” since 1979, and the Olympiad called “Engineering Computer Graphics”, conducted by LETI and ITMO. The peculiarity of the Olympiad in descriptive geometry is its democracy. Its content and organization features are supervised by the professional community, which is united by the section “Geometry, Graphics, Design” of the House of Scientists named after M. Gorky. Competition tasks are developed not only by the organizers. Accepted and suggestions of participants. The content of the Olympiad eventually changes, contributing to its development. Thus, at the suggestion of a number of participants, a comprehensive task was introduced to know the main sections of the course, the task of composition of the task. Despite the withdrawal of the course of descriptive geometry from a number of standards, the fundamentals of this discipline are kept up to date with engineering graphics, which ensures participation in the Olympiad of 7–10 leading technical universities of the city. Olympiad in engineering computer graphics can be attributed to the problem: the level of tasks, focused exclusively on the bachelor degree; on the principles of organization (problem bank of tasks, features of the appeals process); authoritarian chairman of the jury. As a result, it was boycotted by universities, which, unlike the winners, show decent results at All-Russian Olympiads. Among the All-Russian Olympiads, the Olympiad held by MIT stands out. The organizers managed to create a complex competition, which included the ability to solve interesting applied problems on an orthogonal drawing, possession of tools for creating three-dimensional models and drawings of technical products. Given the experience of MIT, the need to create in St. Petersburg an alternative computer graphics competition that is not purely instrumental in nature, the GUT organized an Olympiad called “Total Drawing”. This competition, held under the direction of the chairman of the jury of Professor D.Voloshinov, is gaining popularity. The article discusses and analyzes the principles of organization and the content of these competitions, offers for their modernization and development.

Exploring the work of Antonio Gaudi and his knowledge in descriptive geometry, which develops a spatial imagination, we notice the use of lines, shapes, volumetric geometric images in architectural creativity. In his early work, Antonio Gaudi designs buildings under the influence of the Moorish style, using geometric shapes and lines that emphasize Arabic motifs in the patterns. So in the house of Vissenty, made in the style of modernism, he applied the idea of a self-repeating element of a simple form toa more complex one. In a fragment of the gallery of the city park Guell, which is an example of the urban style, Gaudi used the transformation of one surface to another, while showing the smoothness of lines and the accuracy of surface construction and without violating their regularity.Combining various forms in one building or structure, Gaudi perfectly mastered the geometry of the curved lines of the second and third order in space. To achieve a similar effect of shaping, scientists tried in the 60s of the XX century by constructing curved lines and Bezier surfaces. Gaudi achieved a similar effect of shaping in a practical way.n his work, he used cylindrical, conical and spherical surfaces that smoothly passed one into another, as well as the surfaces of Catalan: a hyperbolic paraboloid, conoid, cylindroid. In creating volumetric interior plastic, the curved lines with a kinematic movement created bizarre shapes of the ceiling, smoothly turning into other geometric shapes of the walls.The staircasein one of the towers of the Sagrada Familia is a geometric image of a helicoid, where a complex geometric shape is taken as the generatrix, and the guides are two helises -cylindrical helical lines of different radii.In the geometric construction of a direct or inclined helicoid, it is necessary to have two guides and a movement step, which can be set mathematically. In any case, such a surface remains one of the most unique in nature because the helicoid is a minimal surface.Park Guell is located in Barcelona on the Carmel hill, an area of 17.2 hectares. It was built in the first half of the last century. The customer, who was Eusebi Güell.He huge park complex includes a territory with residential buildings and comfortable relaxation areas, amazing picturesque gardens, quaint shady alleys, multi-tiered terraces, colorful flower arrangements, winding grottoes and gazebos.Working on a park project, Gaudi was inspired by the beauties of the surrounding nature of the Carmel Upland and its picturesque landscapes. In the project, walking paths stretched across the entire park, the mountains were not specially cut from the terrain to emphasize the natural landscape of nature.Necessary for the construction of the elements of the park: poles and beams, were decorated under palm trees. Despite the fact that the height difference was 60 meters, the master skillfully beat the landscape with bizarre forms, emphasizing the desire of a person from simple to sublime.If you delve into history, you can see that the construction work is divided into three stages: the strengthening of hills and slopes with the arrangement of terraces for curved paths and the erection of walls; the construction of a colonnade, a market and mansions; building a bench in the shape of a snake. To date, all the facilities of the complex have been preserved in their original form. At the entrance to the park there are two houses resembling fabulous gingerbread houses, the walls of which arelined with ceramic fragments. The facade of eachhouse is decorated with a medallion with the inscription “Park Guell”. In Gaudi’s work, the “hundred columns” hall, which is inscribed in the landscape of the hill, is a terrace with 86 columns of 6 meters each. These columns support a ceiling with a bizarre shape of complex geometric surfaces of revolution. The plastic of the ceiling vault is made of modern concrete of the time, the decoration of which is made of ceramic in the form of a mosaic. In practical work, Antonio Gaudi took a self-repeating algorithm that developed in space in the form necessary for his design. Gaudi perfectly mastered the skills and knowledge of the discipline called Descriptive Geometry. Developing the spatial imagination, this discipline offers us all kinds of lines, geometric shapes and three-dimensional bodies, for the embodiment of the ideas of masters of architecture, one of which is Antonio Gaudi.

Improving the quality of products associated with improving the quality of their design, which is achieved by using modern information technologies. Considering the high density layout of a modern transport technology, is an urgent development of mathematical software and automated layout system. The basis for the creation of mathematical development and software development need the steps to geometric modeling as placed objects, and the allocating process. The article discusses the layout automation products with a high density layout (especially means of transport). Since the problem of accommodation is a classical geometrical problem, then it is necessary to develop solutions appropriate geometric models. The article describes the main types of geometric models describing the shape of composable objects, their classification and application. We describe an automated layout problem as a problem of placement of a certain group of objects of specified sizes and shapes in a confined space. The paper shows that with an abundance of models used in modern applied geometry, allowing to describe the geometric shape of objects of any complexity, their use in computer-aided layout does not provide a solution to the problem of automated layout. The article shows the possibilities of modern software and reasons that do not allow its direct use in tasks of automated layout. The mathematical formulation of the problem as a layout optimization problem, indicating its objective function, constraints and performance criteria. An approach (unit normal equations), which allows the creation of geometric models of automated layout, move from exhaustive search of accommodation options composable objects to intelligent automated placement algorithms.

In descriptive geometry, the problem of finding a surface curve section with a plane is common. One such surface curve is a quadric. Due to the increased demand for tasks related to quadric, the synthetic modeling method becomes relevant. In recent years, geometric constructions of dimensions of more than three began to be studied more and more often. Multidimensional geometric shapes in multidimensional space are typically constructed using geometric modeling software. However, without additional building automation tools, software does not sufficiently facilitate human labor. The larger the dimension of the constructions, the more cumbersome and time consuming the drawing process becomes. The increasing complexity of constructions requires automation of constructions that can be traditimatized. Geometric constructions made using automation tools make us rethink the process of structural geometric modeling in descriptive geometry. Within the framework of the article, the algorithm for crossing the N-dimensional hyperquadric with N-1-dimensional hyperspace is presented. Special cases of this geometric construction are also considered: intersection of a three- dimensional quadric with a plane and intersection of a four-dimensional hyperquadric with a three-dimensional space. The implementation of the developed algorithm is carried out using the Simplex system and the built-in interpreter of the prolog logical programming language.

Abstract Among cartographic works, three-dimensional panoramas should be marked out as a special kind of map, which are characterised by visual modes of representing objects in space. The main principles of the creation of both hand-painted and automated maps vector and raster graphics software (Corel Draw and Adobe Photoshop) are considered in the paper. The use of modern information technologies has several advantages over traditional mapping.
