Streaming Real-Time IoT Telemetry to 3D Digital Twins via MQTT & WebSockets
Learn how to bridge MQTT broker telemetry streams into WebGL and WebGPU viewports for live building monitoring and anomaly detection.
Traditional static 3D BIM models lack operational context. Integrating low-latency MQTT message queues transforms static geometry into dynamic Digital Twins reacting to real-time physical conditions.
1. MQTT-over-WebSockets Architecture
To ingest sensor data directly in modern browser clients, edge gateways translate raw MQTT payloads into WebSockets, enabling sub-100ms updates to node properties inside 3D web viewports.
2. Binding Live Data Points to IFC Object GUIDs
Map incoming JSON streams containing temperature, vibration, or occupancy data to individual structural elements via their persistent Global Unique Identifiers (IfcGloballyUniqueId).
3. Dynamic Shader Colorization and Heatmaps
Update custom GLSL/WGSL fragment shaders on the fly to highlight overheating equipment, HVAC airflow pressure shifts, or room usage intensity without re-rendering geometry buffers.
