一覽

Three.js is a JavaScript library for 3D graphics in browsers. Uses WebGL under the hood but abstracts complexity. Used for product visualization, games, AR/VR, data visualization. Salary band: 110–180k USD for specialists. Time to learn: 6–8 weeks. Adjacent to WebGL, game development, and graphics. Growing demand for immersive web experiences.

什麼是 Three.js 3D Graphics

Three.js is an open-source JavaScript library that simplifies WebGL programming for 3D graphics in web browsers. It provides scene management, cameras, lights, materials, geometry, and animation systems. Three.js abstracts WebGL's complexity, allowing developers to build 3D experiences without low-level graphics knowledge. Three.js is used for product visualization (e-commerce), data visualization, browser games, AR/VR experiences, and architectural visualizations. It powers immersive web experiences on modern browsers.

❓ 常見問題

Should I learn Three.js or Babylon.js?
Three.js is more popular and has larger ecosystem. Babylon.js is more feature-complete and often easier. Start with Three.js for community size; switch if needs require Babylon features.
What can I build with Three.js?
Product visualizers, 3D data visualizations, browser-based games, AR/VR experiences, architectural visualizations, physics simulations. Anything 3D that runs in a browser.
How do I optimize Three.js for performance?
Use LOD (level-of-detail), frustum culling, reduce draw calls, optimize shaders, use instancing for repeated objects. Profile with Chrome DevTools. Target 60 FPS.
Can I import models from Blender?
Yes. Export from Blender to glTF format (recommended) or Babylon format. Import into Three.js with loaders. Rig and animate in Blender or Three.js.
Is Three.js suitable for production games?
For casual/indie games, yes. For AAA or performance-critical, consider Babylon.js or game engines (Unity WebGL, Godot). Three.js is sufficient for many indie projects.
