Симулятор виртуальной реальности по оказанию первой медицинской помощи для использования при обучении персонала АСУП

Abstract

The article considers the proposed models and methods of designing, developing and implementing a virtual reality VR simulator on first aid for training specialists of the staff management subsystem of the automated pro-duction management system. Analysis of information about the injured at work in the territory of the Russian Federation is given, according to the data of the Federal State Statistics Service. The system structure has been developed. There is proposed a new approach to creating more realistic 3D models for visualizing in virtual reality, developing clothes for 3D models of people in virtual reality in the Marvelous designer software, and a strategy for optimizing 3D models for loading them into a virtual reality application. The process of model development, types of incorrect and correct model topology, types of high-polygonal model before retopology and low-polygonal model after retopology, the process of baking a normal map in Substance Painter software and a baked normal map, a model without and with a normal map, light adjustment, texturing and baking maps, materials consisting of PBR textures and main maps Albedo, Metallic, Roughness, Normal, Ambient Occlusion, Emission maps and models with and without textures, shaders. There is considered an approach to creating clothing for a human model in ZBrush software, as well as a seam on clothing for 3D models in virtual reality. Algorithms for real-time accounting, interaction with three-dimensional models in real time, as well as an algorithm for the operation of animated objects in a virtual reality simulator have been developed. The simulator has been tested in training the staff of the Moscow state budgetary institution the Center for Innovative Technologies in Leisure and Sports “Progress” and in the professional training program for the profession Car Driver implemented by SBVEI 26KADR in 2019. The positive results of the implementation are described.
