Web-based Digital Twin 3D Visualization

Hi Dear,

I’m looking for a web-based 3D Digital Twin / interactive 3D visualization POC for a cloud-based BMS platform.

The client already collects HVAC data through BACnet/IP, Modbus, MQTT and LoRaWAN, and exposes normalized data to northbound applications through REST API or MQTT.

Initial POC: AHU

We need a detailed AHU 3D model rendered inside a browser using Three.js/WebGL or an appropriate web 3D technology, preferably optimized GLB/GLTF.

The model must be data-driven, not just a static 3D viewer.

The BMS JSON contains:

* Supply/return/mixed/outdoor air temperature
* CHW supply/return temperature
* Humidity, filter DP, duct static pressure, CO₂
* CHW/heating valve position %
* Supply/return fan VFD speed
* Outdoor/return/exhaust damper position
* Fan ON/OFF status
* VFD faults
* Smoke/freeze/filter alarms
* Fan start/stop and damper commands

Required behaviour

JSON values must dynamically control the 3D model.

Examples:

VFD speed → fan animation speed
Valve % → valve position
Damper % → damper angle
Fan status → fan ON/OFF
Alarm/fault → visual alarm state
Temperature/pressure/humidity/CO₂ → live UI values

For the POC, simulated JSON is sufficient, but the architecture should later support the client's REST API/MQTT.

Reusability

This must be designed as a reusable framework for:

AHU, Chiller, Cooling Tower, Pumps, VAV, VRF, STP and other HVAC/Energy/Water equipment.

We want parameter-to-object/animation mapping to be configurable wherever practical rather than hard-coded for one AHU.

POC deliverables

1. Browser-based interactive 3D AHU
2. GLB/GLTF support
3. JSON-driven parameter mapping
4. Dynamic values and animations
5. Fan, valve and damper movement
6. ON/OFF and alarm states
7. Basic BMS-style UI
8. Clean reusable code architecture
9. Documentation for extending the framework
10. Working demo ready for future API/MQTT integration

The main validation is:

JSON → Parameter Mapping → 3D Model → Dynamic Values/Animation

Please provide:

1. Recommended technology/architecture
2. POC cost
3. Timeline
4. What you need from us
5. Examples of similar Digital Twin/IoT/real-time 3D projects

Please quote the AHU POC separately first. If successful, this can become a larger recurring project covering multiple equipment and projects.
