Leveraging WebGL for Interactive and Real-Time Data Visualization through Digital Shadows in Automotive Industry. International Conference on Engineering and Emerging Technologies, ICEET. Kuala Lumpur:Institute of Electrical and Electronics Engineers Inc.ISSN 2409-29832409-2983http://hdl.handle.net/10198/36617The rise of Industry 4.0 and the increase of data captured, as well as its diversification, has intensified the need for advanced data visualization methods that support this volume of information, real-time monitoring and decision-making in industrial manufacturing environments. Traditional dashboards, while widely adopted, often rely on static 2D representations that lack spatial context, limiting their effectiveness in scenarios where complex and three-dimensional physical objects, such as vehicles, are involved. To address this gap, this work presents a WebGLbased module integrated into a dashboard system to enhance the visualization of data captured in vehicle production lines. The proposed module leverages interactive 3D models, designed as digital shadows of the physical counterpart, to provide a more intuitive and immersive understanding of the production state. This system establishes seamless bidirectional communication between the dashboard and the WebGL module, enabling realtime updates and user interactions, while the data captured in the industrial manufacturing workstations by methods such as geometric measuring systems and sensors is mapped to the 3D model, allowing overseers to identify measurement points and potential defects with improved clarity. Based on the combination of interactive visualization with rule-based monitoring, the system supports the pursuit of zero-defect manufacturing. This work contributes with a replicable use case of integrating WebGL into dashboards for industrial applications, highlighting both technical implementation and practical benefits.engWebGL3D Scanning3D ModelsData VisualizationDigital ShadowsIndustry 4.0conference paper10.1109/iceet67911.2025.11424056
