Research on cultural heritage conservation has shifted from emphasizing the digital information process with the advantages of “precision” and “visualization” in the early stage to focusing on the development of “realistic” and “highly experiential” gamified interactive environments. As game technology provides a highly interactive experience, effective communication, and an integrated environment, it brings new application opportunities for the future development of the reconstruction of historical blocks and cultural spaces. This study takes the old city blocks and historic buildings in Taiwan as examples, applies ArcGIS and SketchUp as the information modeling software, uses the Unity3D game engine as the development platform, and carries out the integration and interactive presentation of the scene information model through the two-stage process of information modeling and programming integration. The historical building information model and 3D-GIS attribute data are integrated...

Cultural heritage researchers have recently begun applying Building Information Modelling (BIM) to historic buildings. The model is comprised of intelligent objects with semantic attributes which represent the elements of a building structure and are organised within a 3D virtual environment. Case studies in Ireland are used to test and develop the suitable systems for (a) data capture/digital surveying/processing (b) developing library of architectural components and (c) mapping these architectural components onto the laser scan or digital survey to relate the intelligent virtual representation of a historic structure (HBIM). While BIM platforms have the potential to create a virtual and intelligent representation of a building, its full exploitation and use is restricted to narrow set of expert users with access to costly hardware, software and skills. The testing of open BIM approaches in particular IFCs and the use of game engine platforms is a fundamental component for developi...

This paper outlines a two stage approach for digitally recording cultural heritage sites. This approach involves a 3D modeling stage and the integration of the 3D model into a 3D GIS for further management and analysis. The modeling stage is carried out using a new concept; Historic Building Information Modeling (HBIM) which has been developed at the Dublin Institute of Technology . Historic Building Information Modeling is a system for modeling historic structures from laser scan and photogrammetric data using Building Information Modeling (BIM) software. The HBIM process involves a reverse engineering solution whereby parametric objects representing architectural elements are mapped onto laser scan or photogrammetric survey data. A library of parametric architectural objects has been designed from historic manuscripts and architectural pattern books. These parametric objects were built using an embedded scripting language within the BIM software called Geometric Descriptive Language (GDL). These objects are combined and mapped onto the survey data to build the entire model. After the 3D model has been created the next stage involves integrating the 3D model into a 3D GIS for further analysis. The international framework for 3D city modeling, CityGML has been adopted for this purpose. CityGML provides an interoperable framework for modeling 3D geometries, semantics, topology and appearance properties [13]. The aim of this research is to bridge the gap between parametric CAD modeling and 3D GIS while using benefits from both systems to help document and analyze cultural heritage sites.
Game engines can be regarded as powerful tools in the Cultural Heritage domain, not just as dissemination tools, but for managing the urban context in real time. This case-study is based on the ongoing project of Pietrabuona Castle (Pescia, Italy). It is an interesting example of a stratified historical centre, the conservation and promotion of which might benefit from using a new, integrated survey and alphanumeric data management tool. The method used to survey this medieval fortification had to provide both local institutions and researchers with an interactive tool encompassing several features of Cultural Heritage: from technical (decay, maintenance, environmental risks, etc.) to cultural (urban standard, historical understanding, immaterial features). Due to the cross-disciplinary nature of the ongoing project, we decided to share some major points of our investigation with the scientific community, in particular those concerning our procedure: the opportunity to use interactive applications to display themes of urban settlements as 3D models, based on a survey by laser scanner.

In recent years, considerable efforts have been made by cultural heritage institutions across the globe to digitise cultural heritage sites, artifacts, historical maps, etc. for digital preservation and online representation. On the other hand, ample research projects and studies have been published that demonstrate the great capabilities of web-geographic information systems (web-GIS) for the dissemination and online representation of cultural heritage data. However, cultural heritage data and the associated metadata produced by many cultural heritage institutions are heterogeneous. To make this heterogeneous data more interoperable and structured, an ever-growing number of cultural heritage institutions are adopting linked data principles. Although the cultural heritage domain has already started implementing linked open data concepts to the cultural heritage data, there are not many research articles that present an easy-to-implement, free, and opensource-based web-GIS architecture that integrates 3D digital cultural heritage models with cloud computing and linked open data. Furthermore, the integration of web-GIS technologies with 3D web-based visualisation and linked open data may offer new dimensions of interaction and exploration of digital cultural heritage. To demonstrate the high potential of integration of these technologies, this study presents a novel cloud architecture that attempts to enhance digital cultural heritage exploration by integrating 3D digital cultural heritage models with linked open data from DBpedia and GeoNames platforms using web-GIS technologies. More specifically, a digital interactive map, 3D digital cultural heritage models, and linked open data from DBpedia and GeoNames platforms were integrated into a cloud-based web-GIS architecture. Thus, the users of the architecture can easily interact with the digital map, visualise 3D digital cultural heritage models, and explore linked open data from GeoNames and DBpedia platforms, which offer additional information and context related to the selected cultural heritage site as well as external web resources. The architecture was validated by applying it to specific case studies of Australian cultural heritage and seeking expert feedback on the system, its benefits, and scope for improvement in the near future.

The promotion and dissemination of architectural heritage for cultural enhancement and touristic enjoyment are increasingly focused on innovative ICTs, including 3D Geographic Information Systems, photorealistic models and scenes, and VR/AR immersive digital environments, which enable the interaction of visitors with a variety of informational contents, both educational and specialist. Within the above-mentioned framework, this paper will firstly outline the general objectives of the project "3D-IMP-ACT", which has been funded under the international cooperation programme IPA CBC Interreg Italy-Albania-Montenegro. In this research, some ICT tools are tested and validated to create "virtual networks" of international ancient architectures and sites, based on the identification of "physical networks" of common historic, environmental and technical characteristics and infrastructural connections, in order to address coordinated strategies and transversal policies for development and management. Then, the paper will describe and discuss some results from the design and implementation of the project WebGIS system, which integrates virtual tours of 360° panoramas, 3D models from photomodelling of pictures taken by drones, multimedia contents, and 2D/3D historic evolution schemes within a single platform, where the users are supported in recognizing and exploring the tangible and intangible correspondences among the project pilot-cases. In conclusion, some remarks will be proposed on the potential benefits of the platform as an expert system which supports the technical assessment and control of architectural heritage toward maintenance, refurbishment and conservation.
Beyond Hbim: Serious Games and Procedural Modelling for Heritage Dissemination
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2021
In the study of built heritage, the potential offered by the BIM methodology finds effective application in the knowledge and dissemination process. Today, the HBIM methodology often develops from 3D scanning point clouds with the so-called Scan-to-BIM processes. The complexity that often characterizes the architectural elements of the historical heritage and the lack of information on construction details and geometries, constitute a critical factor that sometimes affects the effectiveness of the application of the BIM methodology. Procedural methods define an approach that can help us when it is necessary to use external modelling tools for the local modelling of complex elements. Algorithmic modelling potentially could significantly reduce the investment normally required in digital content modelling operations, also in terms of time consuming. Furthermore, in procedural modelling, the definition of the detail can be calibrated a priori according to the objectives of the workflow. The research addresses the difficult management of point clouds in workflows aimed at the realization of the so-called serious games, tools that have proved invaluable in educational and teaching processes, as well as in the dissemination and promotion of heritage. Involving a remarkable variety of digital instruments for representation, serious games define a research topic in which the different needs related to the representation of the complexity of the objects can be investigated. Aimed at defining an effective development process for serious games, the paper proposes an HBIM workflow for reconstruction of 3D environments of historic buildings starting from laser scanning surveying approach.

The dissemination of the tangible and intangible values of heritage building represents one of the most important objectives in the field of Digital Cultural Heritage (DCH). In recent years, different studies and research applied to heritage monuments have shown how it is possible to improve the awareness of the architectural heritage through the integration of latest developments in the field of 3D survey, 3D modelling, Building Information Modeling (BIM) and eXtended Reality (XR). On the other hand, this digital workflow requires a huge amount of data sources and a holistic approach to reach a high level of information sharing coming from different disciplines and sectors such as restoration, geomatics, 3D virtual museums and serious gaming. In conjunction with entertainment software and gaming, this research shows the main results obtained during the generative process of digital environments oriented to improve the level of information and to enrich the contents coming from the ...
