Building an IDC Digital Twin with 3D Web Technology: A Front‑End Blueprint

01 Business Background

Rapid growth of Internet Data Centers (IDC) and increasing numbers of self‑built data halls raise the demand for better resource management and operations. A digital‑twin solution based on data visualization and 3D interactive scenes is proposed to meet evolving business and technical needs.

02 Solution Composition

Business Architecture

Field investigations identified a four‑level business chain: region → data hall → room → equipment. Requirements and functional points were derived for each level.

Technical Solution

A three‑dimensional interactive application framework was designed to satisfy the needs of web‑based IDC digital twins.

Key points of the solution:

Lights, meshes and data can be reused across multiple scenes.

View switching is achieved by combining scenes and cameras.

Camera control layer encapsulates interactions such as click, drag and zoom.

3D Application Framework

The framework, named IDC 3D Drama , is built on ThreeJS and offers:

Open capability & business‑driven : ThreeJS‑compatible API, configuration‑driven development.

Efficient restoration : Optimized rendering for visual fidelity and web performance, with a resource library for rapid business shape reconstruction.

Fast integration : Modular import, no special front‑end environment requirements, on‑demand loading and native PWA support.

Business Components

Core IDC models and resources were packaged into reusable components. The generic rack component demonstrates data‑driven real‑time rendering, enabling visual composition through explicit configuration and commands.

03 Technical Principles

Front‑End Application State

SPA Application: The current React SPA. 3D Application: An instance built on the 3D framework, containing multiple scenes, cameras, graphics and data sources.

In a SPA, routing controls page switching. For the digital‑twin, additional challenges include lifecycle management of the 3D view, cross‑page persistence, and bidirectional communication between the 3D view and the page.

User Interaction

User interaction focuses on the camera, using ThreeJS raycasting and camera controls. The framework provides business‑friendly events such as onClick, onDoubleClick, and onMouseover.

Business Component Implementation & Usage

Components follow a defined lifecycle and API, implemented via base class inheritance. The generic rack component example shows how to configure and render it within a business page.

Visual Restoration

A bright “white‑model” style is used, enhanced with directional light, shadow maps, SAO, FXAA and other post‑processing effects to achieve realistic scene appearance.

Other Optimizations

Application performance (model size, loading strategy, device state, network conditions).

Multi‑platform adaptation (mobile interaction, fullscreen browsers).

Large‑screen delivery (screen‑casting control solutions).

04 Case Showcase

Case 01 – IDC Digital Twin (Hangzhou Renhe Data Hall) – PC and mobile links provided.

Case 02 – “Shadow‑less” Cloud PC experience – PC link and QR code for mobile.

05 Planning & Outlook

Future work will enrich applications, tools and resources to deliver a one‑stop digital‑twin solution for IDC operation, resource monitoring, IoT device management and other scenarios, supporting the new‑infrastructure era.
