3D Scanning, Digital Twins & Spatial Data

The Challenge

The construction, survey, and geospatial industries increasingly rely on 3D data to understand and document physical spaces. From laser-scanned point clouds to photogrammetric models and ground resistivity measurements, the volume and complexity of spatial data continue to grow exponentially. Yet the tools for processing, visualising, and sharing this data often lag behind, locked into expensive desktop applications that limit collaboration and accessibility.

Organisations need browser-based platforms that can render complex 3D datasets in real time, support volumetric analysis and temporal playback, and integrate with existing monitoring and survey workflows. The technical challenge of rendering millions of data points in a web browser while maintaining interactive performance requires specialist expertise at the intersection of 3D graphics, data processing, and web engineering.

Our Approach

Digital Tactics developed browser-based 3D visualisation capabilities using three.js and WebGL for hardware-accelerated rendering directly in the browser. For the SOCOTEC/British Geological Survey PRIME instrument project, we built a system capable of rendering 3,410 voxels per device from an 11x31x11 electrode mesh, with volumetric slicing, real-time data switching between sensor channels, and temporal playback animation showing changes over time.

With 3dYu, we created scanning software and a web platform for 3D body scanning, processing raw scan data into usable 3D models. Our work with Plowman Craven and SLATE Technologies extended this expertise into construction survey workflows, while the Point Tagger project developed tools for annotating and classifying point cloud data. Each engagement pushed the boundaries of what could be achieved with 3D data processing and visualisation in web-based environments.

• Browser-based 3D rendering with three.js, WebGL, and Unity WebGL builds
• Volumetric voxel visualisation with slicing, temporal playback, and data switching
• Point cloud processing, annotation, and classification tools
• Augmented reality sandbox and shape detection R&D prototypes

Projects & Clients

The 3dYu platform and 3dYu Scanning Software delivered end-to-end 3D body scanning capabilities, from capture through processing to web-based model viewing. 4D Reality (4D.me) extended this into consumer-facing 3D experiences. Our collaboration with Plowman Craven, one of the UK's leading survey companies, and SLATE Technologies brought our 3D expertise to construction and infrastructure survey workflows at scale.

The Point Tagger project developed purpose-built tools for point cloud annotation, while 3D Mapping and UAV Photo Testing explored aerial data capture and processing pipelines. The Augmented Reality Sandbox and Shape Detection projects advanced our research capabilities in spatial computing and computer vision, feeding insights back into commercial delivery. SurveyScience.ai brought AI-powered analysis to survey data processing.
