Virtual Office 3D
An experimental web project exploring the possibilities of interactive 3D environments in the browser. The application allowed multiple users to move simultaneously within a virtual space, interact with objects, and encounter NPCs, all in real-time via WebSockets. Developed with React Three Fiber for immersive visual experiences.
Overview & Background
Problem Statement: Growing interest in virtual spaces and metaverses raises questions about how to implement performant and user-friendly interactive 3D environments on the web, especially when multiple users need to interact concurrently. The technical challenges in state synchronization and 3D asset management are substantial.
Motivation: To explore the technical feasibility and user experience of real-time multi-user 3D worlds in the browser. The project aimed to leverage React Three Fiber in combination with WebSockets, gaining practical experience with asset integration, animation, and multiplayer synchronization.

Challenges & Solutions
Challenge 1
Real-time Synchronization via WebSockets:
The biggest challenge was implementing a stable and performant WebSocket connection for real-time synchronization of user positions, movements, and object interactions among multiple users. Managing connections and minimizing latency were critical.
Solution
Built a dedicated WebSocket server that efficiently managed user states and distributed updates to all connected clients. Implemented robust message logging and a fine-grained update rate to ensure a fluid multi-user experience
Challenge 2
Pathfinding and Animation of NPCs:
Adding non-player characters (NPCs) required implementing pathfinding algorithms for realistic movement within the space, as well as smoothly integrating their animations.
Solution
Pathfinding and Animation of NPCs:
- Adding non-player characters (NPCs) required implementing pathfinding algorithms for realistic movement within the space, as well as smoothly integrating their animations.
- Solution: Utilized GLB models and the gltf-to-jsx function in React Three Fiber for easy integration of animated characters. Developed simple pathfinding logic (e.g., waypoints) and leveraged Three.js's animation APIs to render smooth NPC movements.
Challenge 3
Integration and Optimization of 3D Models:
Incorporating 3D models from external sources like PolyPizza and optimizing them for performant rendering in the browser.
Solution
Consistently used optimized GLB models and the gltf-to-jsx tool, which transforms 3D assets directly into React components, significantly simplifying integration. Focused on efficient loading and rendering to maintain high browser performance
