The article describes the stages of the process of creating a virtual reality simulator using the example of a standard operating procedure for replacing a check valve on a Christmas tree. A brief overview of the Christmas tree arrangement and an analysis of the stages of the check valve replacement are described. A short algorithm has been developed based on 11 out of 16 implemented stages. The choice of hardware platform and software is substantiated. Using the Christmas tree as an example, the processes of creating a three-dimensional model and unfolding textures in the three-dimensional editor 3ds Max, creating color maps, reflection and texture normals in the graphical editor Substance Painter are described. The process of creating a landscape in the Unity3D environment is described. Oculus Integration and VR TK assets were used in the development of the main scripts.

This paper presents original solutions for creation of training complex learning cosmonauts to control a space jet pack on purpose self-rescue when emergency happens. An approach is proposed in which training is carried out in a virtual environment using virtual reality gloves and headset. The idea is that control of virtual space jet pack model is performed by interaction of virtual hands, copying movements of cosmonaut's hands, with three-dimensional model of jet pack's control panel. To implement the training complex, methods and approaches were developed for movement synchronization simulation of virtual and real hands, as well as simulation of jet pack's control panel and thrusters. Approbation of proposed methods and approaches was carried out as part of our virtual environment system VirSim developed at the SRISA RAS. Results obtained in the paper can be used to create training complex for learning cosmonauts to rescue when they accidentally separate from the International Space Station.

The purpose of thesis was to comprehensively develop the construction project of a long reach compact excavator. Optimal solution was selected and its frames were determined by carrying out classic structural calculations. Then, based on them, a preliminary three-dimensional model was designed in the CAD environment. The prototype was subjected to a series of verification calculations and simulation tests using the finite element method under typical, but also non-standard operating conditions. Then, the structure was optimized and then tested again. Next, technical documentation of the final version was created. In the final part of work, technical and operational parameters of designed compact excavator were summarized and the direction of further actions was determined. The thesis ended with a summary of the observations arose during its implementation.

Archeological Artifacts

The paper puts forward the methodologies for the virtual restoration of the archeological artifacts that were obtained from the various missions. The proposed methodology combines the both the augmented and the virtual reality (C-ARVR) technologies enabling a virtual restoration of the artifacts that were damaged by visualizing the virtual three dimensional model with the actual one. The methodology provides an enhanced perception of the damaged substances. This enables the restoration of the historical artifacts that are more valuable.

Main Research

Up to now, the main research in china about Chang'e satellite and data sent by it is about rail orbit determination and data use, but the study concerning the Lunar Virtual Reality Structure has not appear. Based on Lunar DEM and lunar image having been done, with Super3D Editor as a platform, lunar three-dimensional virtual operating system has been completed. This paper mainly introduces the coordinate transformation, the construction of three-dimensional model and model spatial index, and provides better technology for the information extraction.
