However, due to accessibility issues (e.g., remote location, weak online presence), the Villa remains nearly unknown in comparison to popular sites like Pompeii, despite its cultural importance. VILLAE, a collaboration between archaeologists, classicists, and game designers at the University of South Florida and the University of Arkansas, aims to build academic and public engagement with the Villa through a serious game played directly online using WebGL. Addressing the issues of accuracy in 3D reconstruction versus digital embodiment and meaningful game play, this paper outlines the project's pipeline for synthesizing the extensive 3D documentation of the site to create the digital prototype for an immersive narrative that unfolds the Villa's history against the development of modern archaeology in Italy and focuses the human story and professional life of a pioneering female archaeologist, Ersilia Caetani-Lovatelli.","PeriodicalId":362468,"journal":{"name":"The 26th International Conference on 3D Web Technology","volume":" 18","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132095340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To easily identify such constructional modifications, this paper proposes a smart digital twin for construction site monitoring that supports web-based collaboration with external experts to discuss possibly required solutions to this problem. Therefore, a system pipeline was designed that allows automatic detection and visualization of deviations between real and planning data. In addition, the pipeline allows generating an interactive difference visualization that uses the original planning data as well as the 3D scanned real data. The latter is recorded using an AR-capable mobile device or headset like the Microsoft HoloLens, whereas the mentioned differences are obtained via a point-cloud-based algorithm. The differences between real and planning data are then emphasized on the respective client, which uses X3DOM for visualization. Besides the server part of the pipeline, the application consists of several clients that enable a collaborative discussion between the various stakeholders, such as an AR-based mobile viewer for the craftsman on site and a web-based viewer for the building owner at home or the architect.","PeriodicalId":362468,"journal":{"name":"The 26th International Conference on 3D Web Technology","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114800811","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, upon measuring performance of WebXR scenes, we found users can suffer from high latency while waiting for all 3D objects appear in their field-of-view. This is because storage and fetching of 3D objects in WebXR (and its underlying WebGL libraries) are agnostic to the user’s orientation and location, leading to latency issues. Specifically, fetching of texture files in arbitrary order results in 3D objects waiting on their texture dependencies, and the storage of all objects’ geometry data in one large file blocks individual objects from rendering even if their texture dependencies are satisfied. To address these issues, we propose a systematic prioritization of which 3D objects and their dependencies should be fetched first, based on the user’s position and orientation in the VR scene. To improve efficiency, the geometry data belonging to each 3D object are optimally grouped together to minimize the average latency. Our experiments with various WebXR scenes under different network conditions show that our scheme can significantly reduce the time to all 3D objects appearing in the user’s field-of-view, by up to 50%, compared the default WebXR behavior.","PeriodicalId":362468,"journal":{"name":"The 26th International Conference on 3D Web Technology","volume":"289 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114263995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

X3D version 4 (X3D4) authors have the option to Inline (i.e. load) glTF models directly or else utilize native X3D nodes to create corresponding 3D models. Physically-based rendering (PBR) and non-photorealistic rendering (NPR), with corresponding lighting techniques, are each important additions to the X3D4 rendering model. These lighting models are compatible and can coexist in real-time with legacy X3D3 and VRML97 models (which utilize classic Phong shading and texturing) either independently or composed together into a single scene. The X3D4 approach to representing glTF2 characteristics is defined in complete detail in order to be functionally identical, thus having the potential to achieve the greatest possible interoperability of 3D models across the World Wide Web. Nevertheless, a persistent problem remains in that glTF renderers do not always appear to produce visually identical results. Best practices for mapping glTF structures to X3D4 nodes are emerging to facilitate consistent conversion. This paper describes a variety of techniques to help confirm rendering consistency of X3D4 players, both when loading glTF assets and when representing native X3D4 conversions. Development of an X3D4 conformance archive corresponding to the publicly available glTF examples archive is expected to reinforce the development of visually correct software renderers capable of identical X3D4 and glTF presentation.","PeriodicalId":362468,"journal":{"name":"The 26th International Conference on 3D Web Technology","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126913582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent XR collaboration studies have focused on sharing and understanding the overall situation of the objects of interest (OOIs) and its surrounding ambient objects (AOs) rather than simply recognizing the existence of OOI. The sharing of the overall situation is achieved using three-dimensional (3D) models that replicate objects existing in the physical workspace. There are two approaches for creating the models: pre-reconstruction and real-time reconstruction. The pre-reconstruction approach takes considerable time to create polygon meshes precisely, and the real-time reconstruction approach requires a considerable time to install numerous sensors to perform accurate 3D scanning. In addition, these approaches are difficult to be used on the collaboration in a location beyond the reconstructed space, making them impractical to an actual XR collaboration. The approach proposed in this study separates the objects that form the physical workspace into OOI and AO, models only the OOI as a polygon mesh in advance, and reconstructs the AO into a point cloud using light detection and ranging technology for collaboration. The reconstructed point cloud is shared with remote collaborators through WebRTC, a web-based peer-to-peer networking technology with low latency. Each remote collaborator collects the delivered point cloud to form a virtual space, so that they can intuitively understand the situation at a local site. Because our approach does not create polygon meshes for all objects existing at the local site, we can save time to prepare for collaboration. In addition, we can improve the practicality of XR collaboration by eliminating the need to install numerous sensors at the local site. We introduce a prototype and an example scenario to demonstrate the practicality of our approach.","PeriodicalId":362468,"journal":{"name":"The 26th International Conference on 3D Web Technology","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125363411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
