SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Three.js Fundamentals helps developers bootstrap and reason about 3D scenes in the browser by teaching core Three.js concepts.

Core Features & Use Cases

  • Scene creation, camera configuration, and renderer setup for interactive 3D content.
  • Managing Object3D hierarchies, transforms, lighting, and basic animation loops.
  • Use cases include educational tutorials, product visualizations, and live demos.

Quick Start

Create a simple Three.js scene by importing the library, building a scene, adding a camera and renderer, placing a cube with lighting, and starting an animation loop.

FAQPage Schema
How do I set up a basic Three.js scene with a camera and renderer?▼

To set up a basic Three.js scene, you import the library, build a scene graph, configure a WebGLRenderer, add a PerspectiveCamera or OrthographicCamera, place objects with lighting, and start an animation loop.

What is the difference between PerspectiveCamera and OrthographicCamera in Three.js?▼

PerspectiveCamera and OrthographicCamera are both supported for Three.js scene configuration. PerspectiveCamera mimics human eye depth perception, while OrthographicCamera renders objects without perspective distortion, useful for product visualizations.

How do I manage Object3D hierarchies and transforms in a WebGL scene?▼

Managing Object3D hierarchies in WebGL involves structuring parent-child relationships within a Three.js scene graph, allowing grouped transforms, rotations, and scaling to be applied relative to parent objects during the animation loop.

Does Three.js work for building product visualizations and interactive demos?▼

Yes, Three.js is suitable for building product visualizations and interactive demos. It provides the necessary WebGLRenderer, lighting configurations, and camera controls to prototype and render web-based 3D content effectively.

What's the best way to structure a basic animation loop in Three.js?▼

The best way to structure a basic animation loop in Three.js is using requestAnimationFrame, calling the WebGLRenderer's render method each frame to update the scene graph and Object3D transforms continuously.
