3D Visualisation

Wiki title

3D Visualisation

3D visualisation is the process of creating three-dimensional digital representations of objects, environments, or data using specialized software. These models can be static or interactive, allowing users to view and manipulate them from various angles. Techniques such as modeling, rendering, and animation are used to create realistic or conceptual representations. 3D visualisation is widely applied in industries like architecture, product design, gaming, and digital twin technology due to its ability to provide immersive and detailed visual experiences[1][3][8].

Key concepts

3D visualisation provides a functional solution for digital twins by offering immersive, interactive, and realistic representations of physical systems or assets. Its ability to integrate real-time data and support simulation makes it indispensable for industries requiring detailed analysis and predictive insights. By enhancing spatial understanding and decision-making while enabling collaboration across stakeholders, 3D visualisation significantly elevates the utility of digital twin technology across diverse applications.

In the context of digital twins, 3D visualisation plays a critical role by providing an immersive and functional solution for representing physical assets or systems digitally. A digital twin integrates real-world data with a virtual model to simulate, monitor, and analyse physical entities.

Mechanisms

Immersive and Realistic Representation

3D visualisation allows for highly detailed and lifelike models that mirror real-world counterparts. This level of realism is essential for industries like architecture and urban planning, where stakeholders can explore designs or environments virtually before implementation[1][2].

Enhanced Spatial Understanding

By visualising objects or systems in three dimensions, users gain a better understanding of spatial relationships and structural details. For example, in urban planning or facility management, 3D models provide insights into how components interact within a space[2][4].

Interactive Analysis

3D visualisations in digital twins enable real-time interaction with models. Users can manipulate views, simulate scenarios, or integrate IoT data for live monitoring. This interactivity is particularly valuable in applications like aerospace design or industrial operations where dynamic analysis is required[2][5].

Improved Decision-Making

The ability to simulate processes and visualise outcomes in 3D helps stakeholders make informed decisions. For instance, in manufacturing, 3D digital twins can simulate production workflows to identify bottlenecks or inefficiencies[5][13].

Training and Simulation

3D visualisations facilitate immersive training environments by simulating real-world scenarios. This is especially useful in fields like healthcare or aviation, where hands-on experience is critical but physical training resources may be limited[5][7].

Integration with Real-Time Data

Digital twins enriched with 3D visualization can incorporate real-time data streams from IoT sensors. This enables live monitoring of systems, predictive maintenance, and scenario testing, as seen in industries like energy management and transportation[2][15].

Collaboration Across Stakeholders

By providing a shared visual platform, 3D models enhance collaboration among teams. Designers, engineers, and decision-makers can work together more effectively by visualizing complex systems in a unified format[5][12].

Examples

Platform vs. custom solutions

TwinView demonstrates a foundational approach to 3D visualisation in digital twins by creating an accessible, platform-based solution for building management. The system allows users to navigate through 3D building models in real-time while viewing live streaming sensor data overlaid on the building geometry. Users can click on any space or asset within the 3D model to access live operational data, including temperature, occupancy, and equipment status. This approach bridges the gap between design-phase BIM models and operational facility management, making complex building data accessible to both technical and non-technical audiences.

"One of the important things about TwinView is that we very much wanted to do a platform approach because a lot of digital twins seem to be custom-built applications for a specific building... We built TwinView to be a platform where it's a really easy entry to market—you can actually set this up yourself and you can build on top of the platform. It's an API-first solution." - Adam Ward, TwinView

Data integration and analytics

SmartViz advances the concept by demonstrating how 3D visualisation enables predictive modeling and scenario planning for building performance. The platform integrates IoT sensor data with 3D building models to analyze space utilization, energy consumption, and environmental conditions. Users can transition from map views to immersive 3D digital twins where each space is clickable for both historical and live data analysis. The system uses this 3D context to run simulations, identify energy leakage, and model "what-if" scenarios—such as the impact of layout changes or temperature adjustments on building performance and occupant productivity.

"The idea is you see that building on a map and you start to stream all the data on that platform live. You can see the live information on occupancy and environment. You can also use a historic mode. The idea is that you're making all of that information accessible to a non-technical audience as well as a technical audience, even the end user. And you can go from that map view to the 3D digital twin of that building where you can click on every space and look at the live and historic data." - Shrikant Sharma, SmartViz

Scale and accessibility

Virtual Bradford represents a city-scale implementation of 3D visualisation, created using lidar and drone capture technology to produce an open-source digital twin. The project demonstrates how 3D visualisation can serve multiple stakeholders—from urban planners and architects to citizens and developers. The model encompasses 843 listed structures and serves dual purposes: as a planning consultation tool and as a historical digital twin for heritage preservation. This case study shows how 3D visualisation can democratize urban planning by making development proposals visible and understandable to the public, while also providing technical analysis capabilities for professionals.

"We created a historical digital twin. We can't underestimate the significance—there are 843 listed structures captured in the model. Having a digital model of historical heritage provides a tool that enables analysis and simulations for the continued reuse of those historic structures and how new proposals will interact with them." - Adrian Walker, City of Bradford District Council

Rapid deployment

Akademiska Hus presents a pragmatic methodology for creating scalable 3D digital twins by prioritizing reality capture (lidar scanning) over traditional BIM modeling. Their approach creates detailed 3D geometric representations of existing buildings quickly, which can then be enhanced with IoT sensor data for space utilization and energy analysis. The 3D models serve as a visual canvas for displaying real-time and historical data, enabling stakeholders to understand building performance spatially. This methodology has enabled them to digitize approximately 400,000 square meters of campus buildings, with plans to double this by focusing on speed and business value generation rather than perfect modeling.

"We achieve high-speed scalability by LiDAR scanning first and creating BIM later. Reality capture technology gives us a very precise and detailed geo-referenced digital inventory of our buildings. These models are an excellent foundation for creating BIM in later stages of the building's life cycle. By LiDAR scanning first and creating a digital twin, we can add on BIM at later stages, leaving us open to using new potential modeling technologies that future markets may offer." - Timothy Stahle, Akademiska Hus
