Abstract

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 informative models. The case study is represented by one of the most important Lombard monuments: the Basilica of Sant’Ambrogio in Milan. This study, starting from the 3D survey and the data collection of the historical records of the church, improves the creation of an XR experience that reaches a new level of interactivity for different types of devices (desktop, mobile, VR headset) and users (experts, non-experts).Highlights:Generative modelling requirements and novel grades of generations (GOG) and accuracy (GOA) are presented in order to improve the digitisation of built heritage from the 3D survey, reducing time and costs of the scan-to-BIM process.The holistic value of generative modelling allows experts to create digital worlds able to faithfully and accurately represent the detected reality and improve new immersive environments for Virtual Reality (VR) and Augmented Reality (AR) projects.Immersive environments are created with a mixture of the latest generation software and hardware, allowing users to discover the hidden historical values of built heritage with new levels of interactivity and information.

建筑遗产的扩展现实和信息模型:从扫描到bim过程到虚拟和增强现实

传播遗产建筑的有形和无形价值是数字文化遗产领域最重要的目标之一。近年来，应用于遗产古迹的不同研究表明，如何通过整合3D调查、3D建模、建筑信息建模（BIM）和扩展现实（XR）领域的最新发展，提高对建筑遗产的认识是可能的。另一方面，这种数字工作流程需要大量的数据源和整体方法，以实现来自不同学科和部门的高水平信息共享，如修复、地理信息学、3D虚拟博物馆和严肃游戏。结合娱乐软件和游戏，本研究展示了在数字环境生成过程中获得的主要结果，旨在提高信息水平，丰富信息模型的内容。案例研究以伦巴第最重要的纪念碑之一：米兰的圣安布罗焦大教堂为代表。这项研究从3D调查和教堂历史记录的数据收集开始，改进了XR体验的创建，使不同类型的设备（台式机、移动设备、VR耳机）和用户（专家、非专家）的互动达到了一个新的水平。亮点：提出了世代建模要求和新的世代等级（GOG）和精度（GOA），以提高3D调查中建筑遗产的数字化，减少扫描到BIM过程的时间和成本。生成建模的整体价值使专家能够创建能够忠实准确地表示检测到的现实的数字世界，并为虚拟现实（VR）和增强现实（AR）项目改善新的沉浸式环境。沉浸式环境由最新一代软件和硬件混合而成，使用户可以通过新的互动和信息水平发现建筑遗产的隐藏历史价值。

期刊介绍： Virtual Archaeology Review (VAR) aims the publication of original papers, interdisciplinary reviews and essays on the new discipline of virtual archaeology, which is continuously evolving and currently on its way to achieve scientific consolidation. In fact, Virtual Archaeology deals with the digital representation of historical heritage objects, buildings and landscapes through 3D acquisition, digital recording and interactive and immersive tools for analysis, interpretation, dissemination and communication purposes by means of multidimensional geometric properties and visual computational modelling. VAR will publish full-length original papers which reflect both current research and practice throughout the world, in order to contribute to the advancement of the new field of virtual archaeology, ranging from new ways of digital recording and documentation, advanced reconstruction and 3D modelling up to cyber-archaeology, virtual exhibitions and serious gaming. Thus acceptable material may emerge from interesting applications as well as from original developments or research. OBJECTIVES: - OFFER researchers working in the field of virtual archaeology and cultural heritage an appropriate editorial frame to publish state-of-the-art research works, as well as theoretical and methodological contributions. - GATHER virtual archaeology progresses achieved as a new international scientific discipline. - ENCOURAGE the publication of the latest, state-of-the-art, significant research and meaningful applications in the field of virtual archaeology. - ENHANCE international connections in the field of virtual archaeology and cultural heritage.
