This paper presents a virtual reality (VR) system of evacuation in the cases of various disasters. We considered a combination of disasters under realistic scenarios. Disaster simulations by numerical models were imported into the VR system to express a realistic situation. Not only disaster experts but also designers and non-professionals are able to share realistic experiences for escape from the disasters. This system is useful for performance-based design, planning of escape, disaster prevention, evacuation drill etc. The VR system consists of Building Information Modelling, physical simulation models for disasters and human behaviour’s simulation.

This special issue of ITCON brought together ten papers on Construction 4.0 related topics. These papers are drawn from papers presented at the 20th International Conference on Construction Applications of Virtual Reality (CONVR 2021) held at Teesside University, Middlesbrough TS1 3JN, the UK, in October 2020. CONVR is one of the world-leading conferences in the areas of Virtual Reality, augmented reality and building information modelling. Each year, more than 100 participants from all around the globe meet to discuss and exchange the latest developments and applications of virtual technologies in the architectural, engineering, construction and operation industry (AECO). The conference is also known for having a unique blend of participants from both academia and industry. The overarching theme for CONVR2020 was "Enabling the development and implementation of Digital Twins."

<p><strong>Abstract.</strong> With a growing interest in the use of virtual reality (VR) for dissemination of cultural heritage sites, the question of how to leverage existing documentation as content for virtual experiences becomes a potentially valuable opportunity. Notably, as sites are increasingly documented with building information modelling (BIM) for the purposes of conservation, there is potential to give these models a second life as content for public education and promotion. However, although software exist for viewing BIM in VR headsets, they are inadequate for complex models typical of heritage buildings, and lack functionality for integrating custom didactic content and storytelling. To make BIM performative in VR and allow for custom content, a workflow was developed to translate BIM into game engine scenes — which optimizes geometry following performance guidelines of VR while maintaining the high visual fidelity of the BIM. As a case study, six heritage spaces of the Centre Block of the Canadian Parliament which had been previously documented and modelled by CIMS were prepared for Unity3D, enabling their later use in a storytelling experience.</p>

Virtual Reality (VR) opens new possibilities in the fields of architecture, design and engineering. If combined with Building Information Modelling (BIM) or simpler 3D models, it could be possible to walk into buildings not yet built or to examine designed objects in three dimensions before they are made. This literature review examines studies in which VR was used in architecture, design and engineering as part of design processes. The review highlights promising benefits, such as increased understanding of complex issues concerning design tasks, size and dimensions. At the same time, several challenges are revealed, such as the inability of VR-systems to offer satisfactory functionalities for sketching and designing. Finally, the author discusses how VR can be implemented in relevant subjects in lower and upper secondary school.

The supply of surveying tools and software has grown rapidly in recent decades, as has the quality demands of surveying products from designers, customers and supervisors. This article examines innovative surveying methods and compares the methods in terms of accuracy, availability, and cost. The author, drawing on the views of industry leaders, has outlined future surveyor missions, tasks and opportunities to influence and improve the design process. The article explores the latest spatial data acquisition techniques like laser scanning, digital photogrammetry, LIDAR, Unmanned aerial vehicles (UAV), appliances and perspectives of Building Information Modelling (BIM) and Virtual Reality (VR) and Augmented Reality (AR) as parts of Extended Reality (XR) in design and visualization.

AbstractWe present a summary of the development and clinical use of two custom designed high-fidelity virtual-reality simulator training platforms. This simulator development program began in 2016 to support the phase III clinical trial Archway (ClinicalTrials.gov identifier, NCT03677934) intended to evaluate the Port Delivery System (PDS) developed by Genentech Inc. and has also been used to support additional clinical trials. The two simulators address two specific ophthalmic surgical procedures required for the successful use of PDS and provide state-of-the-art physical simulation models and graphics. The simulators incorporate customized active haptic feedback input devices that approximate different hand pieces including a custom hand piece specifically designed for PDS implantation. We further describe the specific challenges of the procedure and the development of corresponding training strategies realized within the simulation platform.
