three.js (Fork)

这是 three.js 项目的一个fork。

关于这个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

原项目信息

JavaScript 3D library

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.

Examples — Docs — Manual — Wiki — Migrating — Questions — Forum — Discord

Usage

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.
