“…In the built environment, these may either be interiors or outdoor environments (Fritsch and Kada, ). In this area of interest, several methods have been developed to convert geographical information system (GIS) data (Virtanen et al., ) and building models (Bille et al., ) into formats compatible with game engines. This allows creation of a virtual environment for existing data sources.…”

By combining game engines with indoor mapping, it is possible to create interactive virtual environments that represent the real world. In this paper a virtual version of an audio installation in a historic building is produced, where the user freely explores the building and experiences a set of audio clips, creating a virtual radio play. A depth camera indoor mapping system, Matterport, captured a set of staged interiors. The aim was to evaluate the quality and usability of the indoor models and to demonstrate applying them in 3D application development. The quality of the models was evaluated by comparison with laser scanning, revealing limitations with Matterport: increasing the size of the measured area lowered the level of detail and accuracy of volumetric models. The quality of textures was not affected by this limitation, maintaining the appearance of models. To obtain optimised models for mobile 3D applications, a manual revision process was applied.

“…Reapplication of textures, heaviness of the models generated in BIM authoring tools in the rendering and VE navigation, manually re-entering information to gaming engines, and interoperability between the BIM authoring tools and the gaming engines are highly referred challenges in the literature (e.g. Nopachinda, Ergan 2016;Shen et al 2007Shen et al , 2012Dalton, Parfitt 2013;Figueres-Munoz, Merschbrock 2015;Bille et al 2014).…”

Building information models (BIMs) have been used by the Architectural/Engineering/Construction (AEC) industry with a focus on storing and exchanging digital information about building components. However, the untapped potential of BIMs in facility operations and the experience of facility operators while they interact with digital building information have not been understood widely. One of the underlying bottlenecks in the use of BIMs in the FM phase is the lack of interactions with components to easily access information of interest, and the lack of ways to navigate in models with full spatial understanding. Virtual environments (VEs), which represent physical spaces digitally in virtual worlds, enable interactions with virtual components to access information with spatial understanding. The underlying challenges in the conversion of BIMs to VE hinder a streamlined process. This paper provides a detailed analysis of building size, geometric complexities of discipline models and level of geometric granularity as factors contributing to inefficient transformation of BIMs to VE. The paper also provides research findings on a set of computational approaches such as polygon reduction and occlusion culling to overcome challenges and improve the data transfer faced in converting BIMs into VEs over a range and size of facility models.

“…Figueres-Munoz et al (Shiratuddin & Thabet, 2011) indicated that integration of BIM and gaming technology has the potential for combinatorial innovation. A number of previous studies have proposed methods for integrating game engine, BIM, and VR experience for various purposes, e.g., design review (e.g., (Shiratuddin & Thabet, 2011;Wu, 2015)), construction management (e.g., (Bille et al, 2014)), education (e.g., (Wu, 2015;Goedert et al, 2011)), energy conservation (e.g., (Niu et al, 2015;Jalaei & Jrade, 2014;Brewer et al, 2013)), real-time architectural visualization (e.g., (Yan et al, 2011)), and design feedback (e.g., (Hosokawa et al, 2016;Fukuda et al, 2015;Bahar et al, 2013;Motamedi et al, 2016)). …”

“…However, such tools can only provide static outputs with no interaction between the users and the environment e.g., (Bille et al, 2014;Kumar et al, 2014), and are inadequate for dynamically updating or changing design parameters (Kensek & Noble, 2013) and providing simultaneous energy feedback when comparing multiple design scenarios. Moreover, when using traditional tools, designers are unable to directly experience some lighting phenomena that may affect the visual perception of the occupants, e.g., brightness, darkness, glare, or insufficient illumination.…”

Integrating building information modeling and virtual reality development engines for building indoor lighting design

Background: Lighting simulation tools are extending the functionality of Building Information Modeling (BIM) authoring software applications to support the lighting design analysis of buildings. Although such tools enable quantitative and qualitative analysis and visualization of indoor lighting, they do not provide an interactive environment between users and the design context. Moreover, their visualization environments do not allow users to experience visual phenomena such as glare. In addition, lighting energy consumption generated from traditional tools is often separated from the 3D virtual context of the building. Therefore, an incorrect interpretation by designers regarding the relationship between their desirable lighting design and energy feedback may occur. Methods: This research proposes a method and develops a BIM-based lighting design feedback (BLDF) prototype system for realistic visualization of lighting condition and the calculation of energy consumption. Results:The results of a case study revealed that BLDF supports design stakeholders to better perceive and optimize lighting conditions in order to achieve a higher degree of satisfaction in terms of lighting design and energy savings for future occupants. Conclusions: The developed system utilizes an interactive and immersive virtual reality (VR) environment to simulate daylighting and the illumination of artificial lights in buildings and visualizes realistic VR scenes using head mounted displays (HMD). BLDF allows users to interact with design objects, to change them, and to compare multiple design scenarios, and provides real-time lighting quality and energy consumption feedback.
