Abstract
Abstract. This paper describes the results of a research that aimed to focus on a possible approach in the knowledge, representation and dissemination of the Cultural Heritage through CLOUD-to-BIM-to-VR application processes. Starting from reality-based surveys of the current state and information modelling in BIM platforms, the experimentation conducted involved the construction of a VR fruition system for the Simón Ruiz Hospital in Medina del Campo (Valladolid, Spain). An application for mobile devices was therefore designed to describe the artifact and the information acquired - or processed - during the various research phases according to alternative methods and completely independent from the software that generated them. The fruition system is completed with cardboard type supports, for stereoscopic viewing, and controller, to allow the user to navigate in the represented scene and activate the information hotspots that implement the contents of the App.Specifically, the results presented here relate to the operational sequences and products obtained in the organization and programming of the App, structured to allow a multidimensional and multimodal fruition path. The characteristics that connote it, therefore, are related to the setting of incremental levels of knowledge, different by type of content displayed – historical, descriptive, technical, etc. –, form in which it is presented – spherical and photographic images, point cloud, geometric and informative model, textual descriptions, etc. – and integration of hotspots for extend the informative and descriptive content.
Highlights
The renewed interest in the application of virtualization techniques to the Cultural Heritage (CH) and, in particular, the attention paid in recent decades to the integration of the various forms of Extended-Reality (XR) use with the paradigms of information modelling represent the starting point for the experimentation described in this paper
The research focused on the different aspects connoting the connection between the products obtained from the reality-based surveys, the information modelling and the construction of Virtual Reality (VR) environments, pursuing a continuous methodological approach in the collection, processing and management of data relating to the Simón Ruiz Hospital
Unlike the viewers directly associated with the BIM-authoring platforms – specific tools and plugins for VR use of the information model, Unity 3D allows extensive customization during VR programming, being able to intervene on various technical aspects and graphics
Summary
The renewed interest in the application of virtualization techniques to the Cultural Heritage (CH) and, in particular, the attention paid in recent decades to the integration of the various forms of Extended-Reality (XR) use with the paradigms of information modelling represent the starting point for the experimentation described in this paper. It plays a mediating role between reality and the (re)proposed digital one, where the user and the built work are connected through new, alternative and (perhaps) unexpected relationships. The transposition of reality into digital/virtual environments involves careful reflections in the choice of the operative technique to be repeated, in relation to the objectives to be aimed at, because there are many solutions that can be adopted. In this application field, the use of modelling processes and the BIM methodology. This paper tells the results of a research focused on the definition of new tools for understanding and knowledge of the CH, through alternative approaches in the reading, interpretation and visualization of architectural forms, with integrated activities of processing and use of digital data (Figure 1)
