The construction method of interactive geological scene model based on XR technology

The Extended Reality Technology (XR) includes Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR).With the development of computer hardware and software, these technologies have gradually entered the public view and have been applied to various fields.XR technology can make abstract concepts more intuitively and dynamically in geoscience, which can promote geological data visualization, geographic information interaction and geoscience education.This paper introduces the basic concepts and technical means of these technologies, as well as the current situation of the development of Extended Reality Technology in the geoscience, and advanced several interaction patterns in extended reality technology.Besides, in this paper we choose Danyang Quaternary System model to build three demos in each VR, AR and MR devices with each 3 3D-Engines: IdeaVR, Unity 3D and UnrealEngine, explore the characteristics, advantages and disadvantages of the three technology platforms, and summarize the practical methods suitable for geoscience display.This paper also proposes solutions to the problems that may occur when geological data are imported into a 3D engine.
