序

　　又是快两个月没写随笔了，长时间不总结项目，不锻炼文笔，一开篇，多少都会有些生疏，不知道如何开篇，如何写下去。有点江郎才尽，黔驴技穷的感觉。

　　写随笔，通常三步走，第一步，搭建框架，先把你要写的内容框架搭建出来；第二步，添砖，在框架基础上，填写各部分内容；第三步，加瓦，再写好的内容上进行修改，润湿。然后文章的质量，就因人而异了。但不管怎么说，得写，得练，得经受的起各路能人志士的批评指教，至于改不改，那也是写文章的人的事了（通常我是认真接受批评指教的）。

　　你看，写道这里，我又不知道再序些啥了，索性就这样吧。

　　闲话少序，切入正题

前言

　　前面的课程有讲解过库房相关的，但都是密集架库房，档案室库房类的（《如何用webgl(three.js)搭建一个3D库房,3D密集架,3D档案室（升级版）》《如何用webgl(three.js)搭建一个3D库房,3D密集架,3D档案室,-第二课》《如何用webgl(three.js)搭建一个3D库房-第一课》）

　　该篇主要讲解堆放箱体的库房，以及码头集装箱类似的库房场地解决方案。

　　可视化孪生系统实现起来主要是数据源、业务系统、展示方案这三大部分。

　　数据源：就是数据的来源，针对该篇文章，是如何对库房，库位的数据进行采集，录入。物联网厂家通常叫做前端采集模块。

　　　　　　该项目，数据源主要通过 rfid+手动录入的方式，项目中库位主要分了室内和室外两大部分，室内通过门口rfid门禁知道箱子的出入，再通过操作员手动录入箱子的位置（再库位上，详细划分了位置编号）；室外部分直接通过操作员手动录入入库出库信息。

　　　　这里还涉及到车辆定位（叉车），采用的是定位卡+基站以及分站的方式。

　　业务系统：针对采集上来的数据，如何进行有效的处理与存储，如何有效符合客户功能需求，以及要综合考虑数据源结构，展示端需求数据结构，系统性能等。这些都是业务系统的主要功能要求。

　　　　　　　业务系统，也是我们程序员常说的后端服务。

　　展示方案：争对客户需求，设计符合客户要求的交互三维可视化方案。

　　该篇我们主要详细讲解展示端方案。

一、整体效果及功能

1.1、库房外部及周遭场景

//展示货物信息 function showGoodInfo(name, id) {     //显示结构部分     var html = ' XXXXX';     //弹窗     layer.tips(html, "#MarkMessageHelper", {         tips: [1, '#003333'],//弹窗类型与颜色         time: 0,//弹窗自动关闭时长 0表示不自动关闭         area: ["415px", "230px"],//弹窗大小         success: function () {//弹窗显示后回调             setTimeout(function () {                 //数据接口 根据id获取货物详细信息                 webapi.GetAllGoodsInfo(id, function (result) {                     if (result) {                         modelBussiness.cacheData = {                             id: id,                             result: result                         };                         for (var item in result) {//填充弹窗内结构的数据                             $("#devParamValue3D" + id + "_" + item).html(result[item]);                             if (item == "photo_urls") {                                 var _html = "";                                 $.each(result[item], function (_pindex, _pobj) {                                      _html += ' <div style="float:left;cursor:pointer;margin-right:10px;" onclick="modelBussiness.showPics('' + _pobj.url + '','' + _pobj.doctype + '')">' + _pobj.doctype + '</div>';                                 })                                 $("#devParamValue3D" + id + "_photos").html(_html);                             }                         }                     } else {                         $("#devParamValue3D" + id + "_content").html("<font style='color:red;'>获取数据异常</font>");                     }                 })             }, 200);         }     });  }

1.3、车辆出入管理

如何用webgl(three.js)搭建一个3D库房,3D仓库3D码头,3D集装箱,车辆定位,叉车定位可视化孪生系统——第十五课

对进入的车辆实时监控，卡口信息实时展示

实现代码如下：

            var carjp1_4_run = WT3DObj.commonFunc.findObject("car_sanka_3");                       carjp1_4_run.position.x = -858.739;             carjp1_4_run.position.z = 19837.371;               new TWEEN.Tween(carjp1_4_run.position).to({                z: 14344.865             }, 5000).onComplete(function () {                 new TWEEN.Tween(carjp1_4_run.rotation).to({                     y: 0,                 }, 1000).onComplete(function () { }).start();                 new TWEEN.Tween(carjp1_4_run.position).to({                     x: -225.796,                     z: 13523.366                 }, 1000).onComplete(function () {                       layer.tips("", "#MarkMessageHelper")                     layer.msg(`         车牌：<font color='#00ff00'>粤A17001</font><br/>         类型：<font color='#00ff00'>内部车辆</font><br/>         外出：<font color='#00ff00'>2022/10/22 15:36:45</font><br/>         进入：<font color='#00ff00'>2022/10/22 17:56:12</font><br/>         照片：<img src='../img/car_01.png' style="width:100px;height:100px;" />         `)                      setTimeout(function () {                         var dz_3_lg = WT3DObj.commonFunc.findObject("dz_gz_1");                         dz_3_lg.rotation.x = Math.PI / 2;                         dz_3_lg.rotation.z = -Math.PI;                         new TWEEN.Tween(dz_3_lg.rotation).to({                             x: Math.PI                         }, 2000).onComplete(function () {                             new TWEEN.Tween(carjp1_4_run.position).to({                                 x: 1197.955,                                 z: 13308.873                             }, 2000).onComplete(function () {                              }).start();                             new TWEEN.Tween(carjp1_4_run.rotation).to({                                 y: 11.617 / 180 * Math.PI,                             }, 2000).onComplete(function () {                                 new TWEEN.Tween(carjp1_4_run.position).to({                                     x: 10812.744,                                     z: 12807.050                                 }, 6000).onComplete(function () {                                  }).start();                                 new TWEEN.Tween(carjp1_4_run.rotation).to({                                     y: 0,                                 }, 2000).onComplete(function () {                                  }).start();                              }).start();                             setTimeout(function () {                                 new TWEEN.Tween(dz_3_lg.rotation).to({                                     x: - Math.PI / 2                                 }, 2000).onComplete(function () {                                     $("#doAnimationBtn").show();                                 }).start();                             }, 2000);                         }).start();                     }, 2000);                  }).start();             }).start();

1.4、内部仓库场景

双击进入内部室内仓库

如何用webgl(three.js)搭建一个3D库房,3D仓库3D码头,3D集装箱,车辆定位,叉车定位可视化孪生系统——第十五课

绑定双击事件，实现跳转即可

实现展开楼层如下：

ModelBussiness.prototype.tempNameList = []; ModelBussiness.prototype.tempDataList = []; ModelBussiness.prototype.videoDataCache = {}; ModelBussiness.prototype.showFloorState = "close"; //显示楼层内部情况 ModelBussiness.prototype.showBuildFloors = function (buildnub, callBack) {     var _this = this     _this.showFloorState = "open";     var builds = WT3DObj.commonFunc.findObjectsByNames(["ckbuild_486"]);     //隐藏大楼     WT3DObj.commonFunc.setSkinColorByname("ckbuild_486", 0x00ffff);     WT3DObj.commonFunc.changeCameraPosition({ x: 3652.5144280174954, y: 990.805706980618, z: 5107.394022507952 }, { x: 1914.4771268074287, y: -723.8717024746979, z: 2181.6118222317314 }, 500,         function () { });     WT3DModel.commonFunc.changeObjsOpacity(builds, 1, 0.1, 500, function (obj) {         var _obj = WT3DObj.commonFunc.findObject("ckbuild_486");         if (typeof (_obj.oldPositionY) == 'undefined') {             _obj.oldPositionY = _obj.position.y         }         _obj.position.y = 1000000;         _obj.visible = false;          WT3DObj.commonFunc.changeCameraPosition({ x: -1181.6606035933219, y: 7695.800119393643, z: 17124.216668774727 },{ x: 7526.409787213892, y: 2616.2148116624617, z: 7792.131296514065 }, 500,             function () { });          var names = ["zgx_102_f1", "zgx_102_f2", "zgx_102_f3", "zgx_102_f4"];         var floors = WT3DObj.commonFunc.findObjectsByNames(names);         modelBussiness.openFloors(floors, function () {             if (callBack) {                 callBack();             }         });     });  }//显示楼层 ModelBussiness.prototype.openFloors = function (floors, callBack) {     //显示楼层     $.each(floors, function (_index, _obj) {         if (typeof (_obj.oldPositionY) == 'undefined') {             _obj.oldPositionY = _obj.position.y         }         if (_obj.position.y > 100000) {             _obj.position.y -= 1000000;         }         _obj.visible = true;     });     setTimeout(function () {         $.each(floors, function (_index, _obj) {             //展开楼层             _obj.floorPosition = _obj.position.y;             var floor = parseInt(_obj.name.split("_f")[1]);             height = (floor - 1) * 1500 + 50;             new TWEEN.Tween(_obj.position).to({                 y: height             }, 500).start();         });         setTimeout(function () {              if (callBack) {                 callBack()             }         }, 600);     }, 500)  }

1.5、分区块信息

建模时，已经固定分区，所以直接将分区标题固定即可。

如何用webgl(three.js)搭建一个3D库房,3D仓库3D码头,3D集装箱,车辆定位,叉车定位可视化孪生系统——第十五课

实现方法

ModelBussiness.prototype.showAreaGoods = function (code, callBack) {     var objs = [];     var hideobjs = [];     $.each(WT3DObj.scene.children, function (_index, _obj) {         //遍历所有模型，找到对应的模型展示。非对应货物 隐藏         if (_obj.name.indexOf("location2_") == 0) {             _obj.visible = true;             if (_obj.oldPositionY || _obj.oldPositionY == 0) {                 _obj.position.y = _obj.oldPositionY;             }         }         if (_obj.name.indexOf("g_") == 0) {             _obj.visible = true;             if (code == "ALL") {                 _obj.visible = true;             } else {                 if (_obj.name.indexOf("_Area_" + code) > 0) {                     _obj.visible = true;                 } else {                     _obj.visible = false;                 }             }         }     });    }

1.6、单独库位展示

单独库位展示，采用iframe弹框方式，有效节约资源，降低逻辑复杂度。

//展示货物信息 function showGoodInfo(name, id) {     //显示结构部分     var html = CONTENT;     //弹窗     layer.tips(html, "#MarkMessageHelper", {         tips: [1, '#003333'],//弹窗类型与颜色         time: 0,//弹窗自动关闭时长 0表示不自动关闭         area: ["415px", "230px"],//弹窗大小         success: function () {//弹窗显示后回调            }     });  }

1.7、货物搜索定位

　生成模型注意对于批量模型消耗浏览器性能，掉帧问题。这里后面我会用专门的篇幅讲解，如何优化加载大量货物且不掉帧的解决方案。

  //获取区域库位划分数据         webapi.GetAllArea(1, function (result) {             var models = [];             if (result && result.length > 0) {                 $("#room_shelfNub").html(result.length);                 $.each(result, function (_index, _obj) {                     var _color = _obj.color;                     if (_color == "") {                         _color = Math.random() * 16777215 + "";                     } else {                         _color = _color.replace("#", "0x")                     }                     _color = parseInt(_color)                     //生成区域画线                     var model = createAreaModels(_obj.code, _obj.name, _color, _obj.AreaPoints);                     models = models.concat(model);                 })             }             console.log(models);                          WT3DObj.commonFunc.loadModelsByJsons(models, { x: 0, y: 0, z: 0 }, { x: 0, y: 0, z: 0 }, true, function () {              });          })
