A dedicated development team in India employed Three.js to produce 3D models of various scientific phenomena, including the solar system, atomic structure, and biological processes. The app allowed students to interact with the models, view simulations, and take comprehension tests.

Result:

The application was adopted by numerous educational institutions, including schools, enhancing students' learning experiences. The app's interactive features improved information retention and made learning more enjoyable.

Best Practices for Using Three.js to Create Mobile 3D Applications

Here are some best practices to help developers create mobile 3D applications with Three.js that deliver optimal speed and user experience:

1. Optimize Models: Utilize low-poly models whenever possible to reduce the computational workload. Tools like Blender can be used to optimize models before importing them into Three.js.
2. Optimal Use of Textures: Textures can significantly impact performance. Use compressed textures and consider texture atlases to minimize texture bindings.
3. LOD (Level of Detail): Implement LOD strategies to display models with less detail the farther they are from the camera. This can save processing power and improve frame rates.
4. Reduce Draw Requests: Combine geometries and utilize instancing whenever possible to minimize draw calls. This can help maintain smooth performance.
5. Performance Monitoring: Continuously monitor the application's performance using tools like WebGL Insights and Chrome DevTools. Identify and address bottlenecks to ensure seamless functioning on mobile devices.
6. Cross-Device Testing: Test the application on various devices to ensure it functions well with different screen sizes and hardware configurations.
7. Adaptive Style: Ensure the app is responsive and offers a consistent user experience across all orientations and devices.
