About the application of the R-function for geometric modeling of 3D objects of complex shapes in a virtual educational environment

This article is devoted to the creation of a national virtual university platform, geometric modeling of the design of exteriors, interiors and characters in the field of information technology based on 3D technologies. We know that visualization uses geometric splines and polygonal mesh construction methods. In virtual reality systems, each object is represented by a three-dimensional model. The real challenge now is to create custom models that control them. A three-dimensional model of a character is represented by a depth map, dots, a polygonal model, a parametric model describing anthropometric, ansaphic and profile features of a human face. The research process includes the study of the rules of visualization of virtual three-dimensional objects through internal and external models, the theory of geometric modeling, algorithms, methods and algorithms of computer modeling, the use of virtual reality algorithms in education. Today, when engineering and technology are rapidly developing in our country, traveling to the virtual world is of great interest to many. As a result, three-dimensional content and landscape design expand the human imagination and serve to capture our knowledge about the subject and object in our memory. It would be more effective to transfer practical classes in computer halls of educational institutions to the virtual world and organize them in this virtual environment using virtual objects. In addition, all aspects of the subject can be explained and taught, and students will be able to use it virtually. Creating a toolbar that includes all virtual objects becomes a priority. Object-oriented programming technologies and testing methods were used. This article proposes new methods of geometric modeling of three-dimensional objects mentioned above, that is, the constructive logical-algebraic method of R-functions (RFM). This method allows you to depict 3D objects of high complexity.
