The concept of augmented reality offers a more advanced user interface for visualization due to a combination of natural ways to control the change of angle of an object and visualization in a real context. In the process of performing the work, computer graphics, algorithms, and modeling methods were used. The experimental part of the work was carried out using a set of development tools for tracking Vuforia and Unity development tools. Introduction Augmented reality (AR) is an interactive experience of a real-world environment where the objects that reside in the real world are enhanced by computer-generated perceptual information, sometimes across multiple sensory modalities, including visual, auditory, haptic, somatosensory and olfactory. AR can be defined as a system that fulfills three basic features: a combination of real and virtual worlds, real-time interaction, and accurate 3D registration of virtual and real objects. The overlaid sensory information can be constructive (i.e. additive to the natural environment), or destructive (i.e. masking of the natural environment). This experience is seamlessly interwoven with the physical world such that it is perceived as an immersive aspect of the real environment. In this way, augmented reality alters one's ongoing perception of a real-world environment, whereas virtual reality completely replaces the user's real-world environment with a simulated one. Augmented reality is related to two largely synonymous terms: mixed reality and computer-mediated reality. Main part To implement augmented reality technology, two main software components are needed: tracking and visualization. At the moment, researchers and specialists have developed an extensive theoretical and algorithmic base for their implementation in the form of various individual components, as well as in the form of integrated programs and sets of augmented reality development tools. Individual components include libraries and frameworks of computer vision, three-dimensional graphics engines and other solutions. The structure of the visualization system by means of augmented reality implies the presence of the following basic components (figure 1): * Copyright © 2019 for this paper by its authors.
