It entails handling large amounts of data for height and color as well as high-performance algorithms that can benefit from the parallel rendering power of GPUs. The main challenge is (1) to create a detailed renderable mesh using a fraction of the data that is most relevant to a specific camera position and orientation, and (2) to update this mesh in real time as the camera moves while keeping the transition artifacts low. Many algorithms have been proposed for adaptive adjustment of the level of detail (LOD) of large terrains. However, the existing web-based terrain rendering frameworks do not use state-of-the-art algorithms. As a result, these frameworks are prone to classic shortcomings of simpler terrain rendering algorithms such as discontinuities and limited visibility. We introduce a novel open-source web-based framework for rendering high quality terrains with adaptive LOD: Terrender. Terrender employs RASTeR, a modern LOD-based terrain rendering algorithm, while running smoothly with a limited bandwidth on all common web browsers, even on mobile devices. Finally, we present a thorough analysis of our system’s performance when the camera moves on a predefined trajectory. We also compare its performance and visual quality to another well-known framework.","PeriodicalId":277384,"journal":{"name":"Proceedings of the 27th International Conference on 3D Web Technology","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123766545","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}

Our team made use of the API in combination with Web3D technologies to create a spatial audio design tool for digital audiovisual creators. Our primary design challenge was creating an interface for visualizing and manipulating sound design in 3D space. We wanted our interface to be learnable and usable for our target user groups: digital music creators, digital audiovisual 3D artists, and physical audiovisual installation artists who wish to develop ideas in a virtual space. From user interviews, we learned that users needed a detailed visual 3D space as a starting point to populate with sound, as well as fine control over positioning of sound sources. The prototype web app can be used by digital and physical artists to create novel virtual audiovisual experiences, or to model a physical audiovisual installation to share and test with others. More work needs to be done to add direct spatial controls for sound fields and to make the app more natural to use. We asked artists of varying technical skill to use the app and re-create a reference scene, and measured how accurate their re-creation is.","PeriodicalId":277384,"journal":{"name":"Proceedings of the 27th International Conference on 3D Web Technology","volume":"174 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116887700","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}

The best reproducibility can be achieved when performing the benchmarks in the same hard- and software environment. This can be offered as a web service. One challenge of such a web service is the integration of new algorithms into the existing benchmarking tool due to security concerns. In this paper, we present a framework that allows the safe execution of user-uploaded algorithms in such a benchmark-as-a-service web tool. To guarantee security as well as reproducibility and comparability of the service, we extend an existing system architecture to allow the execution of user-uploaded algorithms in a virtualization environment. Our results show that although the results from the virtualization environment are slightly slower by around 3.7% to 4.7% compared with the native environment, the results are consistent across all scenarios with different algorithms, object shapes, and object complexity. Moreover, we have automated the entire process from turning on/off a virtual machine, starting benchmark with intended parameters to communicating with the backend server when the benchmark has finished. Our implementation is based on Microsoft Hyper-V that allows us to benchmark algorithms that use Single Instruction, Multiple Data (SIMD) instruction sets as well as access to the Graphics Processing Unit (GPU).","PeriodicalId":277384,"journal":{"name":"Proceedings of the 27th International Conference on 3D Web Technology","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117182612","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}

Among various use-cases, AR has started to be used as a training tool in manual assembly, by enabling workers to access contextualized digital information overlaid in the physical world. However, very few AR solutions have been adopted so far in industrial sectors, mainly because of technical and acceptability issues, as well as the effort to create AR contents. In this paper we present an AR training system designed for and within the framework of manual assembly production. The proposed approach aims to find the right balance between usability, effectiveness, user acceptance and authoring efforts, to address significant industrial challenges and provide an AR training tool adapted to the shop floor context. We demonstrated the usability and effectiveness of the proposed AR system in multiple experiments and comparatively evaluated authoring efforts with the state-of-the-art. Overall, our proposal reported excellent usability scores and was almost unanimously preferred by the participants to the experiments. Authoring was almost twice as fast as the state-of-the-art while the error rate during training was zero, validating therefore the effectiveness of the system.","PeriodicalId":277384,"journal":{"name":"Proceedings of the 27th International Conference on 3D Web Technology","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121408724","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}

While the 3D Master for engineering & manufacturing is rather established, availability of 3D data along the full value chain e.g., as part of the Digital Thread, and the ability to easily relate it to other business information is still a huge challenge. On top of this, Digital Twins introduce the demand to dynamically link 3D data with IIoT, AI and other business information to visually bring such Digital Twins to live or even into Mixed Reality applications, adding another level of complexity. Building on established Web technology patterns, we experienced that an API-based harmonization over (brownfield) data backends and file formats can help to establish a \"single source of truth\" as a prerequisite for the required agile utilization of 3D data and highly flexible interconnectivity. Many solutions rely on explicitly exporting and preparing use case or application specific subsets of 3D data before making such available, often heavily limiting its utilization on the way. Instead, a high level of interconnectivity is achievable by combining a virtualization of 3D data and algorithms with a unified addressing scheme to abstract over file boundaries and formats while enabling dynamic resolution and mapping of contained 3D data elements with business information on many levels. In our talk, we will present the underlying approach and explain its utilization throughout several industrial use cases in the area of Digital Twins with a focus on dynamic linkage and enrichment of 3D product data across software, solution and format boundaries.","PeriodicalId":277384,"journal":{"name":"Proceedings of the 27th International Conference on 3D Web Technology","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122179785","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}

Digital Therapeutics (DT) have grown exponentially in the last decade, and could be a stepping stone for dyslexia therapy. Making full use of new technologies, they offer new treatments for various disorders. The advancement and diffusion of Virtual Reality (VR) technologies are a new step in the therapeutic domain, notably for the treatment of neurological troubles. In this paper we propose a hybrid VR interface using eye-tracking (ET) and Brain-Computer Interface (BCI) with a gamified application for the rehabilitation of dyslexia. This prototype was designed in collaboration with medical professionals to create a gamified set of exercises adapted in 3D for dyslexia rehabilitation. The interface VR-ET-BCI serves as a monitoring device for the patient and a therapy evaluator for the practitioner. As of today, it lacks yet the clinical trials to show validated results, but an increase in motivation and adherence to therapy is expected.","PeriodicalId":277384,"journal":{"name":"Proceedings of the 27th International Conference on 3D Web Technology","volume":"469 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123661747","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}
