WebGL和three.js的关系是啥样的？

Posted 2023-05-17

webgl和three.js是共生关系。两者的区别如下：

webgl: html5官方的Web 3D解决方案，并且以网页形式进行展示

three.js: 基于webgl的3D框架，three.js在它的基础上进行了进一步的封装和简化开发

所以three.js会继承webgl的所有优势，并且更快速地绘制3D立体图像，高效体现在：

iframe在线分享：无论是PC端还是手机端，只需要单击项目所在链接即可运行

支持浏览器查看：省去了传统游戏安装客户端的麻烦，同时保证了项目代码不被泄露

支持跨平台推广：微信平台兼容性的快速发展，进一步降低WebGL 2.0的推广成本

但常规的html+css+javascript基础远远不够，要想hold住three.js，需要了解专业的3d开发知识，这也是学习曲线较长的卡点。

thingjs在线平台推荐了解一下，也是基于Webgl的3D类库，这两年在国内兴起，对于前端开发转3D更加容易，因为它把3D专业概念这一过程都简化了，打包成类库，直接用javascript就可以调用材质、灯光、空间变换等概念。

学习曲线变短，这是相对于three.js的一个很大的优势，代码变少，开发门槛降低，出错率更低。

3D的未来一定是虚拟漫游技术，在消费者端以及企业端，都有发展前景，我所在的物联网行业，3D可视化主要用于远程管理和安全监控，想看项目案例可登录官网-资源中心查看。

如何用webgl(three.js)搭建一个3D库房-第一课

three.js,webGL,3D库房,3D机房

今天我们来讨论一下如何使用当前流行的WebGL技术搭建一个库房并且实现实时有效交互

第一步、搭建一个3D库房首先你得知道库房长啥样，我们先来瞅瞅库房长啥样（这是我在网上找的一个库房图片，百度了“库房”一下，找不到合适的全景，我们也只能窥一斑思全豹了，就它了，特此声明：此图片归原作者所有 非本人所拍，拿来只是给读者做个案例）

下面是我用webgl做出来的3D效果图（当前展示没有货物时的整体模拟）：

 

第二部、开干

　1、 首先我们创建一个页面，引入各种需要的库文件

        <script src="/js/jquery-2.2.2.js"></script>
　　<script src="/js/commonFunction.js"></script>
　　<script src="../js/tldesign3D/tl3DLoadData.js"></script>
　　<script src="/js/tldesign3D/tlcoreBSP.js"></script>
　　<script src="/js/tldesign3D/tlcoretween.js"></script>
　　<script src="/js/tldesign3D/sourse/Detector.js"></script>
　　<script src="/js/tldesign3D/sourse/OBJLoader.js"></script>
　　<script src="../js/tldesign3D/sourse/ParticleEngine.min.js"></script>
　　<script src="/js/tldesign3D/tlcoreControls.js"></script>
　　<script src="/js/tldesign3D/TransformControls.js"></script>
　　<script src="/js/tldesign3D/stats.min.js"></script>
　　<script src="/libs/layer/layer.js"></script>

　　2、开始写代码

　　　　a、搭建场景，要想webGL 3D展示 首先要创建画布，搭建场景

　　　　　　创建一个div 放置画布

　　　　　　

 <div id="canvas-frame" class="canvas_frame"></div>

　　　　　　初始化画布与场景

 1     tl3dCoreObj = new tl3DCore();
 2     tl3dCoreBusiness = new TL3DCoreBusiness();
 3     var initOption = {//画布参数
 4         antialias: true,
 5         loadSyn: false,//是否启用异步加载
 6         showHelpGrid: false,//是否显示网格线
 7         clearCoolr: 0x002323,
 8         clearColorOp: 1,
 9     };
10     var Aobjects=[];//对象列表
11     tl3dCoreObj.inittl3DCore(\'canvas-frame\', initOption, Aobjects);
12     tl3dCoreObj.start();//开始吧

　　　　　好了 就这么简单 所有需要的3D场景、渲染器、摄像机等等基础已经搭建好了 

　　　　b、开始搭建建筑

　　　　　　先创建地板，分析一下 这个地板主要是绿色地板 加上黄色标线、我们可以让美工先将地板所需要的贴图画好，也可以直接自己画用模型创建，这里我们可以自己画

　　　　　　

Aobjects.push({
    "show": true,
    "uuid": "",
    "name": "floor",
    "objType": "floor",
    "length": 2000,
    "width": 1500,
    "height": 10,
    "x": 0, "y": 0, "z": 0,
    "style": { "skinColor": 16777215, "skin": { "skin_up": { "skinColor": 1529655, "side": 1, "opacity": 1 } } },
    "showSortNub": 4,
    "animation": null,
    "dbclickEvents": null,
    "scale": { "x": 1, "y": 1, "z": 1 },
});
Aobjects.push({ "show": true, "uuid": "", "name": "line_5", "objType": "line", "length": 3, "width": 40, "height": 2, "x": 601.986, "y": 8.801, "z": -730.723, "style": { "skinColor": 16777215, }, "showSortNub": 5, })

效果酱紫的：

　　　　紧接着我来创建围墙，为了便于用户操控，库房的顶部不用画

　　　　　　　　　　

Aobjects.push(

这时候有点样子了 有点感觉了，下面就是细节了 正所谓细节决定成败，即使是个演示，我们也得添加窗户 门 盆栽 窗台 门框什么的

b、搭建货架 货物等等

基础场景已经搭建好了 下面就是搭建货架了

for(var i=1;i<=36;i++){
    Aobjects.push({
        "show": true, "uuid": "", "name": "shelf_" + i + "_1", "objType": "GroupObj",
        "scale": { "x": 1.5, "y": 1, "z": 1.2 },
        "position": { "x": 595 + 90 * i, "y": -95, "z": 140  + 40 * i }, "showSortNub": 54,

    });

    Aobjects.push({
        "show": true, "uuid": "", "name": "shelf_" + i , "objType": "GroupObj",
        "scale": { "x": 1.5, "y": 1, "z": 1.2 },
        "position": { "x": 595 + 90 * i, "y": -95, "z": 140 }, "showSortNub": 54,

    })
}

 

 

添加36个货架之后，整个场景的帧率变成了14帧 这样的体验效果是非常不好的 

所以需要调用优化算法 将场景总物体的画布算法进行优化 

//优化算法
tlcore3DObj.commonFunc.MergeOptimizationByNames([
\'cM_shelf_1\',\'cM_shelf_1_1\',\'cM_shelf_2\',\'cM_shelf_2_1\',
\'cM_shelf_3\',\'cM_shelf_3_1\',\'cM_shelf_4\',\'cM_shelf_4_1\',
\'cM_shelf_5\',\'cM_shelf_5_1\',\'cM_shelf_6\',\'cM_shelf_6_1\',
\'cM_shelf_7\',\'cM_shelf_7_1\',\'cM_shelf_8\',\'cM_shelf_8_1\',
\'cM_shelf_9\',\'cM_shelf_9_1\',\'cM_shelf_10\',\'cM_shelf_10_1\',
\'cM_shelf_11\',\'cM_shelf_11_1\',\'cM_shelf_12\',\'cM_shelf_12_1\',
\'cM_shelf_13\',\'cM_shelf_13_1\',\'cM_shelf_14\',\'cM_shelf_14_1\',
\'cM_shelf_15\',\'cM_shelf_15_1\',\'cM_shelf_16\',\'cM_shelf_16_1\',
\'cM_shelf_17\',\'cM_shelf_17_1\',\'cM_shelf_18\',\'cM_shelf_18_1\']);

 

最后得到结果是场景帧率又回到了60帧

好了 ，第一课先讲到这里吧

下集预告：

　　第二课我们将详细讲解如何添加货物，货架容量管理、以及动态操作货物上下架 、厂房的温湿度 空调 通风 防火 消防定位等操作

　　通过可视化操作 直接控制厂房中各种具体设备
