As virtual reality (VR) and the corresponding 3D documentation and modelling technologies evolve into increasingly powerful and established tools for numerous applications in architecture, monument preservation, conservation/restoration and the presentation of cultural heritage, new methods for creating information-rich interactive 3D environments are increasingly in demand. In this article, we describe the development of an immersive virtual reality application for the Imperial Cathedral in Königslutter, in which 360° panoramic photographs were integrated within the virtual environment as a novel and complementary form of visualization. The Imperial Cathedral (Kaiserdom) of Königslutter is one of the most important examples of Romanesque architecture north of the Alps. The Cathedral had previously been subjected to laser-scanning and recording with 360° panoramic photography by the Photogrammetry & Laser Scanning lab of HafenCity University Hamburg in 2010. With the recent rapid development of consumer VR technology, it was subsequently decided to investigate how these two data sources could be combined within an immersive VR application for tourism and for architectural heritage preservation. A specialised technical workflow was developed to build the virtual environment in Unreal Engine 4 (UE4) and integrate the panorama photographs so as to ensure the seamless integration of these two datasets. A simple mechanic was developed using the native UE4 node-based programming language to switch between these two modes of visualisation.

The recent and rapid developments of immersive, interactive 3D environments have been critical in advancing interfaces for entertainment, design, and education. For cardiovascular research, our laboratory and others have been able to use such software tools for the construction of heart models from DICOM files. These models can then be printed in hard or soft plastic from a 3D printer. In general, such models are considered useful for surgical planning and education; these modalities are being applied as critical tools in the field of cardiovascular research. Recently, the development of virtual reality (VR) has introduced a new modality for exploring 3D virtual structures with high resolution, high flexibility, and fast turn-around times. Until recently, the adoption of these technologies has been hindered by the high costs of VR goggles and the complexities in their setup. New developments in phone software and hardware, however, have alleviated some of these difficulties by allowing smartphone screens, graphics units, and gyroscopes to provide the necessary technologies for VR. In this way, phones can be placed inside a headset holder and used freely, without being connected to the computer. Here we explore the utility of using this VR setup in the context of internal heart anatomy visualization.

Accessibility Evaluation

With the rapid development of the air transport industry, more attention is paid to interior ergonomics analysis which directly affects the time and cost spent during design. To provide a quick and human-in-loop accessibility way to evaluate accessibility in aircraft cabin, a new method based on virtual reality is proposed. In this method, the digital mock-up model is converted to other format which is need to build a virtual environment first, then virtual environment is built and a virtual hand is driven through tracking hand’s position by A.R.T(Advanced Realtime Tracking ) system to carry on accessibility evaluation in the virtual environment. Based on above-mentioned method the aircraft cabin accessibility evaluation system is designed and realized, which is verified by one case of a certain aircraft cabin. The result shows this method is simple and useful, offering a new way for accessibility evaluation in aircraft cabin.

Virtual reality simulation may significantly benefit a geographically dispersed learner demographic in the medical outpatient setting. Our research used an immersive virtual reality platform as a novel way to recreate high-risk medical scenarios targeted for office-based emergencies. Using a design-based research approach we designed virtual-reality-based simulation scenarios to prepare interprofessional office personnel for emergencies. Learners were connected using laptop computers, via a browser interface, with learner controlled team member avatars and educator controlled patient avatars. The virtual environment was modeled after a multi-provider healthcare office setting in a large suburban health network. Evaluation occurred via post-event surveys and feedback transcribed from video recordings and debriefings. Three office-based emergency scenarios were created (chest pain, respiratory distress/allergic reaction, and suicidal risk), with progressively smaller changes to the virtual environment with each iterative improvement. In total, 18 individuals representative of a typical outpatient office interprofessional care team participated in the pilot study. Qualitative design-related feedback from participants and faculty improved the educational environment, artifacts, and scenarios. Participant feedback was overwhelmingly positive and enthusiastic about the use of virtual reality-based simulations to explore teamwork, build scope of practice, and rehearse infrequently used clinical skills. We successfully created novel outpatient virtual reality simulations in a first-person-perspective virtual environment. Pilot testing revealed successful rapid development, implementation, and participant orientation, with the ability to present learning opportunities. Future efforts will include assessments and attempt to overcome development barriers by switching to a more versatile platform.

<p><strong>Abstract.</strong> Virtual Reality (VR) is a highly topical subject in many branches of science and industry. Thanks to the rapid development and advancement of computer technology in recent years, it can now be used to a large extent, with more detail to show and is now more affordable than before. The use of virtual reality is currently devoted to many disciplines and it can be expected that its popularity will grow progressively over the next few years. The Laboratory of Photogrammetry at the Czech Technical University in Prague is also interested in VR and focuses mainly on documentation and visualization of historical buildings and objects. Our opinion is that in the field of virtual reality there is great potential and extensive possibilities. 3D models of historical objects, primarily created by photogrammetric IBRM technology (image based modelling and rendering) or by laser scanning, gain a completely different perspective in VR. In general, most of the newly designed buildings are now being implemented into BIM. For certain projects, historical buildings or constructions should also have implemented into BIM. As a basic input into BIM, an accurate 3D spatial documentation of the condition is needed with special accent to additional information like engineering networks, materials, etc. Creating BIM is one thing, visualizing a model is another. The historical object is irregular and it is difficult to create its simplified form as the CAD model; it is much easier with modern buildings. The question is always the appropriate type of visualization, where virtual reality can be a very useful technology. So-called game engines such as Unreal engine or Unity are used to create a virtual world. These are highly sophisticated tools that make it possible to create a suitable environment, where you can place created models and then view and analyse them with the help of VR glasses. In our contribution, we would like to show an example of a technology line that allows you to convert an object documented by laser scanning into virtual reality. An older industrial building prepared for future reconstruction was chosen as a case study. This object was scanned by a laser scanner, a 3D model was created and material types and engineering networks were added into the model.</p>

Recent building emergency management research has highlighted the need for the effective utilization of dynamically changing building information. BIM (building information modelling) can play a significant role in this process due to its comprehensive and standardized data format and integrated process. This paper introduces a BIM based virtual environment supported by virtual reality (VR) and a serious game engine to address several key issues for building emergency management, for example, timely two-way information updating and better emergency awareness training. The focus of this paper lies on how to utilize BIM as a comprehensive building information provider to work with virtual reality technologies to build an adaptable immersive serious game environment to provide real-time fire evacuation guidance. The innovation lies on the seamless integration between BIM and a serious game based virtual reality (VR) environment aiming at practical problem solving by leveraging state-of-the-art computing technologies. The system has been tested for its robustness and functionality against the development requirements, and the results showed promising potential to support more effective emergency management.

Virtual reality immerses individuals in 3D environments where spatial properties are similar to those of real life. Virtual reality can therefore be effective and relevant in the study of memory processing, especially when spatial properties are involved. We studied the effect of a 20-minute rest period on memory performance for associative and relational learnings. Eighty-one participants were placed in a virtual environment in which they learned 24 associations implicating objects and their respective precise location. As expected, the performance of associative memory was improved by a rest period between study and test phases. We discuss these results and the benefits of using an immersive virtual environment for such memory investigation. In addition, elaborating our environment was highly informative and led to several recommendations that we believe could be useful for researchers who would like to rely on virtual reality for investigating memory.

<p><strong>Abstract.</strong> “A picture is worth a thousand words”: a famous quote about knowledge dissemination but also literally true. The documentation of cultural heritage (CH) monuments is carried out by measurements and photos and stored in 3d models &amp;ndash; not by textual information alone. So what could be a more straightforward way to inform the public about CH than visual information? This approach can be extended not only by providing static images or videos from predefined angles but by giving the user the opportunity to interactively explore the virtual representation and interact with the scene. Recent advances in contemporary Virtual Reality (VR) have made it available to more people as prices have dropped. New devices have entered the market so that VR is not limited to VR labs, but is available even at home. With modern head-mounted displays the user can immerse himself in the virtual CH monument to explore and interact with it. Game engines offer tools for rapid development of interactions and help to produce visually appealing worlds.</p><p>In this paper is presented the generation of a virtual 3D model of Rumeli Hisarı, an Ottoman fortress at the Bosporus in Istanbul, Turkey (Fig. 1) and its processing for data integration into the game engine Unity. The project has been carried out as a co-operation between BİMTAŞ, a company of the Greater Municipality of Istanbul, Turkey and the Photogrammetry &amp; Laser Scanning Lab of the HafenCity University Hamburg, Germany with the aim of a VR application for an immersive and interactive visualisation of the fortress using the VR system HTC Vive. The workflow from data acquisition to VR visualisation, including the necessary programming for navigation, is described. Furthermore, the possible use (including simultaneous multiple users environments) of such a VR visualisation for a CH monument is discussed.</p>

It is very important to study and explore the application of virtual reality technology in landscape garden design, especially in the current environment of triple network integration and Internet of Things construction, to promote and facilitate the rapid development of digital landscape garden design in China. In this paper, we study the implementation method of virtual landscape gardening system and establish a virtual environment based on the ancient city of Yangcheng. On the computer platform, we study and realize a virtual roaming system of medium complexity with more complete roaming functions. Using the Quest3D software platform, a desktop-type virtual garden simulation system was developed, focusing on the virtual reality modeling technology method and virtual system implementation. The experimental results show that the GPU-accelerated drawing method based on GLSL can significantly improve the drawing frame rate of 3D garden landscape vegetation scenes with a small amount of scene data and has a certain feasibility. Based on the OpenSceneGraph (OSG) graphics rendering engine, the visualization of various types of 3D landscape models is realized, and the spatial layout of various types of landscape with parametric control is realized through digital vector layers, which flexibly manage and organize various garden elements and reasonably organize the spatial topological relationship between various types of landscape in 3D space. By integrating cross-platform ArcGISEngine components, the basic data of garden scenes including terrain data and vector data are managed. Through scene view cropping and hierarchical detail modeling technologies, the drawing efficiency and rendering real time of the garden landscape are improved. It realizes interactive 3D scene browsing and provides a six-degree-of-freedom all-round display of the overall landscape.
