这个项目可以实现,该项目的目标是将three.js移植到微信小程序。
下载build目录中的three.weapp.min.js到小程序相应目录。或者你可以构建自己的版本 兼容性
基本模型
OrbitControls
TrackballControls
TextureLoader
GLTFLoader gTLF模型, glb模型加载
OBJLoader obj模型加载
STLLoader
Animation system
Raycaster
DDSLoader or MTLLoader 待测试

<view style="height: 100%; width: 100%;" bindtouchstart="documentTouchStart" bindtouchmove="documentTouchMove" bindtouchend="documentTouchEnd" >
<canvas type="webgl" id="c" style="width: 100%; height:100%;" bindtouchstart="touchStart" bindtouchmove="touchMove" bindtouchend="touchEnd" bindtouchcancel="touchCancel" bindlongtap="longTap" bindtap="tap"></canvas>
</view>
js
import * as THREE from '../../libs/three.weapp.min.js'
import { OrbitControls } from '../../jsm/loaders/OrbitControls'
Page({
data: {},
onLoad: function () {
wx.createSelectorQuery()
.select('#c')
.node()
.exec((res) => {
const canvas = THREE.global.registerCanvas(res[0].node)
this.setData({ canvasId: canvas._canvasId })
const camera = new THREE.PerspectiveCamera(70, canvas.width /...点击查看剩余70%
