Multiple Window 3D Scene Synchronization with Three.js and LocalStorage
A proof-of-concept project demonstrating how to synchronize a Three.js 3D scene across multiple browser windows or tabs using the browser's LocalStorage API.
Project Introduction
Summary
This project provides a minimalist example showing how to keep the camera perspective of a Three.js 3D scene synchronized across several browser windows or tabs using LocalStorage as a simple communication channel.
Problem Solved
Addresses the challenge of maintaining a consistent 3D view or interactive state across multiple independent browser windows without requiring a dedicated backend server.
Core Features
Multi-Window Camera Synchronization
Synchronizes camera position, rotation, and view frustum across all open browser windows displaying the scene.
LocalStorage State Broadcasting
Uses the browser's LocalStorage as a simple, serverless mechanism for broadcasting state changes between windows.
Three.js Integration
Builds upon the Three.js library for rendering and managing the 3D environment.
Tech Stack
Use Cases
The core technique demonstrated in this project can be adapted for various scenarios requiring coordinated visual output or interactive state sharing across multiple browser windows or displays.
Interactive Exhibitions or Installations
Details
In an exhibition or art installation, a 3D model can be viewed from different angles or detail levels on multiple screens, all controlled synchronously from a single point or interaction.
User Value
Creates a more dynamic and multi-dimensional viewing experience for visitors.
Collaborative 3D Model Review
Details
Allow multiple team members to view the same 3D design model simultaneously in their respective browser windows, with one person's navigation actions reflected in others' views for collaborative review.
User Value
Facilitates real-time discussion and alignment on 3D assets across a team.
Multi-Monitor Monitoring or Dashboard Systems
Details
Display different dashboards or control panels related to a central 3D scene (e.g., a factory layout) on different monitors, while keeping the main view synchronized.
User Value
Enhances situational awareness by providing coordinated, specialized views.
