Virtual Reality of Earthquake Ground Motions for Emergency Response

Ground motions interface earthquake science and engineering to advance understanding of seismic hazards and risk. Virtual reality provides an attractive tool to extend knowledge of the research community to a larger audience. This work visualizes emergency response under extreme motions, in the CAVE of the MARquette Visualization Laboratory. The visualization (a) displays ground motions (from the science community), (b) inputs these motions to structural models (from the engineering community) and illustrates the resulting responses, (c) translates structural responses to damage states of building elements, (d) creates a virtual room subjected to the perception associated with such earthquake shaking, and (e) introduces the human element of emergency response in this immersive environment. Building upon previous work on earthquake simulations, performance-based earthquake engineering (PBEE), building information modeling (BIM), and earthquake awareness, this study integrates elements of PBEE and BIM within the CAVE environment to provide visual information for decision making. Real-time or near real-time information via earthquake early warning (EEW) and structural health monitoring (SHM) further facilitates response within a limited time frame. As advanced technologies contribute to the future of community resilience, visualization plays an emerging role in connecting earthquake science, engineering, and policy

Using Virtual Reality Technology in Oil and Gas Industry

This article introduces the research of virtual reality technologies used in the oil and gas industry. The industry is so vast that the technologies used there are radically different. Various aspects of oil and gas production were considered, such as geodata modeling, real-time production visualization technology. The problems and possible solutions for translating CAD models into virtual reality applications are indicated. Also, using virtual reality technology, can increase the speed of work and reduce the risk of errors, which is extremely important in the oil and gas industry. As well as the benefits of learning and using virtual reality to improve learning and understanding of production processes

Using mixed reality for the visualization and dissemination of complex 3D models in geosciences: application to the Montserrat massif (Spain)

In the last two decades, both the amount and quality of geoinformation in the geosciences field have improved substantially due to the increasingly more widespread use of techniques such as Laser Scanning (LiDAR), digital photogrammetry, unmanned aerial vehicles, geophysical reconnaissance (seismic, electrical, geomagnetic), and ground-penetrating radar (GPR), among others. Furthermore, the advances in computing, storage and visualization resources allow the acquisition of 3D terrain models (surface and underground) with unprecedented ease and versatility. However, despite these scientific and technical developments, it is still a common practice to simplify the 3D data in 2D static images, losing part of its communicative potential. The objective of this paper is to demonstrate the possibilities of extended reality (XR) for communication and sharing of 3D geoinformation in the field of geosciences. A brief review of the different variants within XR is followed by the presentation of the design and functionalities of headset-type mixed-reality (MR) devices, which allow the 3D models to be investigated collaboratively by several users in the office environment. The specific focus is on the functionalities of Microsoft’s HoloLens 2 untethered holographic head mounted display (HMD), and the ADA Platform App by Clirio, which is used to manage model viewing with the HMD. We demonstrate the capabilities of MR for the visualization and dissemination of complex 3D information in geosciences in data rich and self-directed immersive environment, through selected 3D models (most of them of the Montserrat massif). Finally, we highlight the educational possibilities of MR technology. Today MR has an incipient and reduced use; we hope that it will gain popularity as the barriers of entry become lower.This research was funded by MCIN/ AEI/10.13039/501100011033: PID2019-103974RB-I00 and by Interreg V-A, POCTEFA: EFA364/19.Peer ReviewedPostprint (published version

Managing the mining cycle using GeoVisionary

Managing the mining cycle from exploration through to evaluation, planning, construction, operation and finally mine closure can involve many datasets in different formats. To be able to visualise all of these different datasets in one environment is important to locate mineral/ore deposits, moderate risks, increase mining efficiency, monitor the impact on the surrounding environment and communicate these factors to stakeholders. Typically, GIS – Geographical Information Systems have been used to manage the life cycle of a mine, however the three dimensional (3D) complexity is lost in these two dimensional (2D) systems. Virtalis alongside the British Geological Survey, have developed the GeoVisionary software which provides the means to aid the management of many aspects of the life cycle of a mine using a combination 2D, 3D and 4D data in the same virtual environment
