这是 three.js 项目的一个fork。
这个fork的目的是加强几何算法能力,并添加一些辅助工具
主要修改包括:
- 添加了几何面板中的面法线工具(FaceNormalsHelper)
预期添加更多的几何算法:
- 三角网格的面积、周长、重心等计算方法
- 凸包、三角剖分
- 简化、细分
- 修复、对齐
- 投影、裁剪
- 碰撞检测、拾取
- 切片
- 显示顶点、面、边的索引

The aim of the project is to create an easy-to-use, lightweight, cross-browser, general-purpose 3D library. The current builds only include a WebGL renderer but WebGPU (experimental), SVG and CSS3D renderers are also available as addons.

This code creates a scene, a camera, and a geometric cube, and it adds the cube to the scene. It then creates a WebGL
renderer for the scene and camera, and it adds that viewport to the document.body
element. Finally, it animates the cube within the scene for the camera.
import * as THREE from 'three';
const width = window.innerWidth, height = window.innerHeight;
// init
const camera = new THREE.PerspectiveCamera( 70, width / height, 0.01, 10 );
camera.position.z = 1;
const scene = new THREE.Scene();
const geometry = new THREE.BoxGeometry( 0.2, 0.2, 0.2 );
const material = new THREE.MeshNormalMaterial();
const mesh = new THREE.Mesh( geometry, material );
scene.add( mesh );
const renderer = new THREE.WebGLRenderer( { antialias: true } );
renderer.setSize( width, height );
renderer.setAnimationLoop( animate );
document.body.appendChild( renderer.domElement );
// animation
function animate( time ) {
mesh.rotation.x = time / 2000;
mesh.rotation.y = time / 1000;
renderer.render( scene, camera );
}
If everything goes well, you should see this.
Cloning the repo with all its history results in a ~2 GB download. If you don't need the whole history you can use the depth
parameter to significantly reduce download size.
