如何用webgl(three.js)搭建处理3D园区、3D楼层、3D机房管线问题（机房升级版）-第九课（一）

写在前面的话：

说点啥好呢？就讲讲前两天的小故事吧，让我确实好好反省了一下。

　　前两天跟朋友一次技术对话，对方问了一下Geometry与BufferGeometry的具体不同，我一下子脑袋短路，没点到重点定义，被朋友嘲笑一番，亏还搞了three.js 这么久，这么简单的基础知识尽然不能对答如流，原来都是假把式。着实尴尬至极，尴尬至极....

　　朋友间的调侃，本是玩笑，但认真思考，不无道理。正所谓温故而知新，也是我们程序员的必须课程，不仅仅是学习利用新技术，对自己常用的老技术也要时长翻看一下，加强记忆，加深理解。

　　后来我还真好好的整理总结了一下Geometry与BufferGeometry，查漏补缺，也算为时未晚也。

　　一句话，这两个对象的主要区别：主要在数据结构上，BufferGeometry非常高效，主要是因为数据直接放在一个连续的GPU内存空间中，有效减少向 GPU 传输上述数据所需的开销，而three.js后期版本中的geometry最终都转化为bufferGeometry,但始终是比bufferGeomerty多了一步，而且还是从CPU的geometry对象传输到GPU的bufferGeometry对象的一个夸硬件传递过程，所以后期也不建议用geometry了。

序：

在三维机房管理系统中，我们已经可以看到很多实现3d机房的可视化管理方案，常见的功能有动力环境管理、安防监控、资产管理与运维，包括我的前面的文章也有过常规3D机房方案的介绍，可以看我前面的文章（使用webgl(three.js)创建科技版3D机房，3D机房微模块详细介绍(升级版三)—— 1）。

再很多3D机房方案中，管线管理.一直是无法切实解决的痛点。主要原因有如下几个：

1、种类繁杂，机房管线线路繁杂，光是线路类型就包括了强电，弱电走线、光纤网线、消防管线、甚至包括国防线（政策上是规避展示的）

2、施工图纸整理繁杂，涉及到各种类型的线路，施工图都来源一大堆，着实无法入手

3、建模工作量大，线路的建模，是最繁杂的，除了线路多，走势还错综复杂

那么针对上面的痛点，我们又该如何解决。

首先是素材来源问题，记得高中学过，唯物主义辨证方法论的思想，牵牛我们要牵牛鼻子，既然线路繁杂，何不挑重点先解决，数据中心这个行业，管线最关心的还是光纤网络线路，而且是只正对数据服务器的网络线路，其它什么强电弱电，甚至是机房内部的动环系统传感器走线，都不是那么重要。所以我们先提出主要矛盾。重点解决机房数据业务的网络走线即可。

然后是技术实现方面：

有三种方案选择：

　　1、全程建模，通过建模的方式实现走线展示，这虽然准确，但哪有那么多的人力物力去建模，还有建模过程中，也不能确保没有遗漏与错搭。

　　2、数据节点驱动：只保存每条线路的关键节点，使用代码生成的线路方式。这很大程度上减少了工作量，但是整理的工作量也不小。

　　3、逻辑线路：只记住起点与经过的设备节点以及终点，自动智能化生成线路。线路不按照实际走向，只记录描述线路上设备的逻辑点位。

我们的解决方案是采用后面两种，虚实结合。

好了 闲话少叙，归入正题：

一、定义：

管道：顾名思义，就知道是指放线缆的固定建筑，有时候是铁管道，有时候是水泥管道

井：每隔一段管道就会有一个便于施工人员维护的井出现

线缆：通常情况下，是放在管道里面的粗黑粗黑的电缆。

电路：是指在线缆里面的一根一根的电线，通常一根电缆里面有几根或者十几根电路

光纤：在电路里面的光纤

二、效果与代码实现：

1、整体园区效果，我们还是采用深色科技蓝风格（科技的主流风）。模型我们还是采用代码创建的方式，楼宇标号采用精灵模型。这里的井盖采用黄色标亮，便于识别。

全场景实现主要代码如下：

function threeStart(_height) { // dataFunc 获取机柜，空调，墙等设备的json对象
    WT3DModel = new WT3D();   // 实例化 3D 核心对象，见 WT3D.core.js 文件。
    var initOption = {
        antialias: true, // 启用平滑、抗锯齿效果
        loadSyn: false, // 是否启用异步加载
        showHelpGrid: false, // 是否显示网格线
        clearCoolr: 0x4068b0,  // 背景色
        clearColorOp: 0,    // 透明度
    };
    //初始化模型
    var models = [];
    httpGetSyn("../models/build.json", function (res) {
        models=res;
    });
    //q {x: -1886.6067471471795, y: 4391.583740697971, z: -5331.98996721255}
    //WT3DObj.controls.target
    //q {x: 66.88861133235778, y: 755.2546885005784, z: 750.5239600058044}
    //加载效果
    showLoadingNoLine(
            models.length,//模型个数
            null,
            roomConfig.cameraPostion,
            roomConfig.cameraTarget,
            function () {//加载完成后回调
                modelBussiness = new ModelBussiness();
                modelBussiness.init();
                 pageindex = new Page();
                pageindex.initPage();
                //旋转注册
                WT3DObj.mouseMoveRotateEvent = function (v) {
                    pageindex.transLeftBall(v);
                }
                //拓展功能
                WT3DObj.commonFunc.transToScreenCoord = function (point) {
                    var _this = WT3DObj; var screenCoord = {};
                    var vector = new THREE.Vector3(point.x, point.y, point.z);
                    vector.project(WT3DObj.camera);
                    screenCoord.x = (0.5 + vector.x / 2) * _this.width; screenCoord.y = (0.5 - vector.y / 2) * _this.height; return screenCoord;
                };
                WT3DObj.commonFunc.transToThreeCoord = function (x, y) { var _this = WT3DObj; var pX = (x / _this.width) * 2 - 1; var pY = -(y / _this.height) * 2 + 1; var p = new THREE.Vector3(pX, pY, -1).unproject(WT3DObj.camera); return p; };

            });
    console.log(models);
    var Aobjects = {  // 给3D对象绑定事件
        objects: models,
        Animation: [
            {
                obj_name: "",
                obj_animation: function (_obj) {

                },
                animationType: 0, // 动画类型 -1永久循环执行 0触发执行 >=1执行多少次
                aniInterval: 1000, // 执行时间间隔 毫秒
            }],
        events: {
            dbclick: [
                {
                    obj_name: "ALL",
                    obj_event: function (_obj, face,c,d) { // 被选中的对象 被选中的面
                        // 此处设置双击聚焦
                        {
                            modelBussiness.dbClickSelect(_obj, face);
                            if (_obj.name.indexOf("build") == 0 || _obj.name.indexOf("ecn") == 0) {
                                return;
                            }
                            modelBussiness.commonFunc.ZoomINShow(_obj, face, c);
                        }
                    }
                },
            ],
            mouseDown: [
              {
                  obj_name: "ALL",
                  obj_event: function (_obj, face, objs) { // 被选中的对象 被选中的面
                      if (window.location.href.indexOf("index.html") >= 0) {
                      } else if (window.location.href.indexOf("floor.html") >= 0) {
                          showFloorDetail(_obj);
                      }
                  }
              },
            ],
            mouseMove: [
                {
                    obj_name: "ALL",
                    obj_event: function (_obj) {
                    console.log(_obj.name);
                    return true;//返回true表示移动
                }
            },
            ]
        },
        //WT3DModel.viewState;表示0编辑状态 1表示运行状态
        btns: []
    }

    if (parent != null && parent.Aobjects_objects != null) {
        Aobjects.objects = parent.Aobjects_objects;
    }
    //修改btns

    //优化Aobjects 此处用于优化 可以先异步加载图片

    Aobjects.imageList = [];
    imageUUIDList = [];
    //遍历获取图片资源
    function getImageList(obj) {
        if (obj && typeof (obj) == "object") {
            $.each(obj, function (_index, _obj) {
                if (_obj && _obj.imgurl) {
                    var imgObj = {};
                    imgObj.uuid = _obj.imgurl;
                    imgObj.imgurl = _obj.imgurl;
                    if ($.inArray(imgObj.uuid, imageUUIDList) < 0) {
                        imageUUIDList.push(imgObj.uuid);
                        Aobjects.imageList.push(imgObj);
                    }
                }
                getImageList(_obj);
            });
        }
    }
    getImageList(Aobjects.objects);
    if (_height != null && typeof (_height) != 'undefined' && _height == 0) {
        $("#canvas-frame").height($(document).height());
    }
    //检查是否存在动态资源需要加载
    var dynamicSource = [];
    $.each(Aobjects.objects, function (_index, _obj) {
        /*
        动态资源结构
        {
               name: '',
               objType: 'dynamicSource',
               file:"";
               loadedCallBackFuncName:""
           }
        */
        if (_obj && _obj.objType && _obj.objType == "dynamicSource") {
            dynamicSource.push(_obj);
        }
    });
    if (dynamicSource.length > 0) {
        WT3DModel.additionModels = {};
        var loadednub = 0;
        $.each(dynamicSource, function (_index, _obj) {
            $.getScript(_obj.file).done(function () {
                /* 耶，没有问题，这里可以干点什么 */
                loadednub++;
                if (loadednub == dynamicSource.length) {
                    $.each(dynamicSource, function (_dindex, _dobj) {
                        if (_dobj.loadedCallBackFuncName && _dobj.loadedCallBackFuncName != "") {
                            eval(_dobj.loadedCallBackFuncName + "()");
                        }
                    });
                }
            })
                .fail(function () {
                    /* 靠，马上执行挽救操作 */
                    console.log("文件加载失败");
                });
        });
    }
}

2、显示地下所有管道，实现方式也比较简单，只需要隐藏上方的建筑与园区地面，把管道显现出来即可。这里可以看到一个园区渐变隐藏的效果。

代码实现：

//隐藏园区模型
ModelBussiness.prototype.hideYuanquModel = function (cb) {
    if (!this.helpBuildModels) {
        this.helpBuildModels = WT3DObj.commonFunc.findObjectsByNames(this.helpBuildNames);
    }
    // WT3DObj.commonFunc.changeObjsOpacity(this.helpBuildModels, 0,0.5, 1000, function () {});
    WT3DObj.commonFunc.changeObjsOpacity(this.m_yuanquModels, 1,0.2, 1000, function () {
        modelBussiness.hideDistance()
        WT3DObj.commonFunc.findObject("backGround").visible = false;
        cb&&cb()
    });
}
ModelBussiness.prototype.showYuanquModel = function (cb) {
    if (!this.helpBuildModels) {
        this.helpBuildModels = WT3DObj.commonFunc.findObjectsByNames(this.helpBuildNames);
    }
    WT3DObj.commonFunc.changeObjsOpacity(this.helpBuildModels, 0.5, 0, 1000, function () {});
    WT3DObj.commonFunc.changeObjsOpacity(this.m_yuanquModels, 0.2, 1, 1000, function () {
        cb&&cb()
     });
}

3、井下走线方式展现,可以查看井下每条线路的信息，便于运维人员运维查看管理

主要代码逻辑：

//双击线缆
ModelBussiness.prototype.dbClickSelect = function (_obj, _face, formRoute, searchParam) {
    var _this = this;
    if(_obj.name.indexOf('jing_line_')>-1){//线缆
        $("#guangLan").hide()
        _this.inVisibleJing(function () {
            $(".cableImg").css("transform", "scale(1)");
        })
    }
}
var jingNameArr = ['jing_jing', 'jing_guandao', 'jing_line_4', 'jing_line_6', 'jing_line_7', 'jing_line_8', 'DirectionalLight_29'];
// 显示井
ModelBussiness.prototype.visibleJing = function (cb) {
    WT3DModel.commonFunc.changeObjsOpacityByName(jingNameArr, 0, 1, 1000, function () {
        cb && cb()
    })
}
// 隐藏井
ModelBussiness.prototype.inVisibleJing = function (cb) {
    WT3DModel.commonFunc.changeObjsOpacityByName(jingNameArr, 1, 0, 1000, function () {
        cb && cb()
    })
}
//绑定悬停事件
ModelBussiness.prototype.bindHoverEvent = function () {
    //悬停回调
    WT3DObj.mouseOverCallBack = this.mouseOverCallBack;
    //进入回调
    WT3DObj.mouseOverInCallBack = this.mouseOverInCallBack;
    //离开回调
    WT3DObj.mouseOverLeaveCallBack = this.mouseOverLeaveCallBack;
    //悬停触发时间长度
    WT3DObj.mouseOverTimeLong = 1000;
    window.onresize = function () {
        modelBussiness.mouseEvent();
    };
}
//悬停
ModelBussiness.prototype.mouseOverCallBack = function (_obj, face) {}
//鼠标滑入回调
ModelBussiness.prototype.mouseOverInCallBack = function (_obj, face, _objs) {
    console.log(_obj)
    var obj=_obj.name.indexOf("_OBJCREN_")>-1?_obj.parent:_obj;
    if(_obj.name.indexOf("jing_line_")>-1){
        showLightLineData(obj.name);
    }
}
//鼠标滑出回调
ModelBussiness.prototype.mouseOverLeaveCallBack = function (_obj, face, nowobj) {
    var obj=_obj.name.indexOf("_OBJCREN_")>-1?_obj.parent:_obj;
    if(_obj.name.indexOf("jing_line_")>-1){
        $("#guangLan").hide()
    }
}

4、双击管线，查看管线内部光纤信息，快速掌握光纤走向与状态。

  var _this = this;
    if(_obj.name.indexOf('jing_line_')>-1){//显示详细线缆
        $("#guangLan").hide()
        _this.inVisibleJing(function () {
            $(".cableImg").css("transform", "scale(1)");
        })

5、展现所有线缆信息，标注线缆，以及点击查看线缆信息。

这里主要用精灵模型，精灵贴图的方式。

function createPicModel(param) {
    var models = [{ "objType": "envMaps", "envMaps": [{ "name": "skybox", "imgs": ["../img/3dImg/skyboxs/1/UP.jpg", "../img/3dImg/skyboxs/1/UP.jpg", "../img/3dImg/skyboxs/1/UP.jpg", "../img/3dImg/skyboxs/1/UP.jpg", "../img/3dImg/skyboxs/1/UP.jpg", "../img/3dImg/skyboxs/1/UP.jpg"] }, { "name": "skybox2", "imgs": ["../img/3dImg/water.jpg", "../img/3dImg/water.jpg", "../img/3dImg/water.jpg", "../img/3dImg/water.jpg", "../img/3dImg/water.jpg", "../img/3dImg/water.jpg"] }] }, { "show": true, "showHelper": true, "uuid": "", "name": "DirectionalLight_8", "objType": "DirectionalLight", "shadowCameraNear": 1, "shadowCameraFar": 1, "shadowCameraLeft": 0, "shadowCameraRight": 0, "shadowCameraTop": 0, "shadowCameraBottom": 0, "shadowMapWidth": 1024, "shadowMapHeight": 1024, "distance": 5000, "targetName": "floor", "intensity": 1, "color": 16775651, "castShadow": true, "position": { "x": 4222.947, "y": 4379.619, "z": 2859.101 }, "showSortNub": 8, "customType1": "", "customType2": "", "animation": null, "dbclickEvents": null, "shadowCameraFov": null, "decay": null, "BindDevId": null, "BindDevName": null, "devInfo": null, "BindMeteId": null, "BindMeteName": null }];

    }
    if (param.width && param.length) {

    }
    if (param.builds && param.builds.length > 0) {
        $.each(param.builds, function (_index, _obj) {
            for (var i = 1; i <= _obj.floors; i++) {
                var points = [];
                if (_obj.shape && _obj.shape.length > 0) {
                    $.each(_obj.shape, function (_sindex, _sobj) {
                        _sobj.type = "nomal";
                        points.push(_sobj);
                    });
                } else {
                    points = [{ "x": (0 - _obj.width / 2), "y": (0 - _obj.length / 2), "type": "nomal" }, { "x": (0 - _obj.width / 2), "y": (_obj.length / 2), "type": "nomal" }, { "x": (_obj.width / 2), "y": (_obj.length / 2), "type": "nomal" }, { "x": (_obj.width / 2), "y": (0 - _obj.length / 2), "type": "nomal" }]
                }
                console.log(points);
                if (i == _obj.floors) {
                    models.push({ "show": true, "uuid": "", "name": "parkbuild_" + _obj.name + "_f_" + i, "objType": "ExtrudeGeometry", "position": { "x": _obj.x, "y": 151 * (i - 1), "z": _obj.y }, "style": { "skinColor": 16711680, "skin": { "skin_up": { "skinColor": 6992593, "materialType": "Phong", "side": 2, "opacity": 0.8, "imgurl": "../../img/3dImg/wall/top3.jpg", "repeatx": true, "width": 0.01, "repeaty": true, "height": 0.01, "envMap": { "name": "skybox", "reflectivity": 0.4, "refractionRatio": 0.8, "combine": "" } }, "skin_down": { "skinColor": 16711680, "materialType": "Phong", "side": 1, "opacity": 1 }, "skin_side": { "skinColor": 13099775, "side": 2, "materialType": "Phong", "opacity": 0.65, "imgurl": "../../img/3dImg/wall/inner-wall11.jpg", "repeatx": true, "width": 0.01, "repeaty": true, "height": 0.004, "envMap": { "name": "skybox", "reflectivity": 0.8, "refractionRatio": 0.8, "combine": "" } } } }, "scale": { "x": 1, "y": 1, "z": 1 }, "shapeParm": { "points": points, "holes": [] }, "extrudeSettings": { "amount": 150, "curveSegments": 2, "steps": 2, "bevelEnabled": true, "bevelThickness": 1, "bevelSize": 1, "bevelSegments": 2, "extrudePathPoints": [] }, "showSortNub": 800 + i, "customType1": "", "customType2": "", "animation": null, "dbclickEvents": null, "rotation": [{ "direction": "x", "degree": -1.5707963267948966 }, { "direction": "y", "degree": 0 }, { "direction": "z", "degree": 0 }], "BindDevId": null, "BindDevName": null, "devInfo": null, "BindMeteId": null, "BindMeteName": null })

                }
            }
        });
    }
    return models;
}

6、双击线缆，查看线缆内的光纤数据信息。

7、标注井深与管深。便于施工与土建规避。知道深度，能有效辅助运维人员下井准备，而且再土建施工时，能有效规避风险，不会有挖断线缆情况发生。

代码实现：

//显示管道
ModelBussiness.prototype.showGD = function (cb) {
    this.hideDistance()
    var guandao = WT3DObj.commonFunc.findObject("yqgx_guandao");
    guandao.position.y =0;
    guandao.visible = true;
    WT3DObj.commonFunc.changeObjsOpacity([guandao], 0.1, 1, 500, function () {
       cb&&cb()
    });
}
//隐藏管道
ModelBussiness.prototype.hideGD = function (cb) {
    var guandao = WT3DObj.commonFunc.findObject("yqgx_guandao");
    WT3DObj.commonFunc.changeObjsOpacity([guandao], 1, 0.1, 500, function () {
        guandao.position.y = -100000;
        guandao.visible = false;
        cb&&cb()
    });
}

// 显示深度
ModelBussiness.prototype.showDeep=function(cb){
    modelBussiness.showDistance()
    // 缓存相机位置
    this.cameraPostion_cache=JSON.parse(JSON.stringify(WT3DObj.getCameraPosition()));
    this.cameraTarget_cache=JSON.parse(JSON.stringify(WT3DObj.getCameraTarget()));
    var position={x: -520.4091455366863, y: 144.35504820242926, z: 627.9302907417292};
    var positionTarget={x: -263.56663925875796, y: -150.20066997406482, z: 240.69791289652335};
    WT3DObj.commonFunc.changeCameraPosition(position,positionTarget,1000,function(){cb&&cb()})
}
//隐藏深度
ModelBussiness.prototype.hideDeep = function (cb) {
    var yuanqu=WT3DObj.commonFunc.findObject(["zysjzx_yuanqu_7"]);
    WT3DObj.commonFunc.changeObjsOpacity([yuanqu],0.1,1,500,function(){
        modelBussiness.hideDistance()
        WT3DObj.commonFunc.findObject(["backGround"]).visible=true;
        WT3DObj.commonFunc.changeCameraPosition(roomConfig.cameraPostion,roomConfig.cameraTarget,1000)
        cb&&cb()
    })
}

// 显示井深、管道深尺寸标注
ModelBussiness.prototype.showDistance=function(){
    var that=this;
    WT3DObj.commonFunc.findObject("backGround").visible=false;
    WT3DObj.commonFunc.findObject("zysjzx_yuanqu_7").visible=false;
    WT3DObj.commonFunc.changeObjsOpacity(this.m_shenduModels,0.2,1,1000,function(){
        for(var i=0;i<that.m_shenduModels.length;i++){
            that.m_shenduModels[i].visible=true;
        }
    })
}
// 隐藏井深、管道深尺寸标注
ModelBussiness.prototype.hideDistance=function(){
    WT3DObj.commonFunc.findObject("backGround").visible=true;
    WT3DObj.commonFunc.findObject("zysjzx_yuanqu_7").visible=true;
    for(var i=0;i<this.m_shenduModels.length;i++){
        this.m_shenduModels[i].visible=false;
    }
}

8、线缆检索。能够根据线缆属性，快熟定位查看线缆走势与信息。

ModelBussiness.prototype.showAllFloorLinesModel = function (callBack) {
    var _this = this;
    this.openFloors(function () {
        if (!_this.FloorLines) {
            var linesname = [];

            for (var i = 1; i <= 3; i++) {
                linesname.push("zb_f" + i + "_H1xi");
                linesname.push("zb_f" + i + "_H2xi");
                linesname.push("zb_f" + i + "_Ixi");
                linesname.push("zb_f" + i + "_H1cu");
                linesname.push("zb_f" + i + "_H2cu");
                linesname.push("zb_f" + i + "_Icu");
        }
        _this.FloorLines = WT3DObj.commonFunc.findObjectsByNames(linesname);
        }
        var outlines = [];
        if (_this.FloorLines.length > 0) {
            $.each(_this.FloorLines, function (_index, _obj) {
                _obj.visible = true;
                if (_obj.name.indexOf("cu") >= 0) {
                    outlines.push(_obj);
                }
            });
        }
        var vmodes = [];
        $.each(WT3DObj.scene.children, function (_index, _obj) {
            if (_obj.name.indexOf("r1_11_1") >= 0 || _obj.name.indexOf("r1_11_2") >= 0 ) {
                vmodes.push(_obj);
            }
        });
        vmodes = vmodes.concat(_this.FloorLines);
        _this.VitureAllFloors(function () {
            WT3DObj.commonFunc.changeObjsOpacity(vmodes, 0.1, 1, 100, function () {
                WT3DObj.commonFunc.changeObjsOpacity(outlines, 1, 0.1, 500, function () {
                    if (callBack) {
                        callBack();
                    }
                });
            });
        });
    })
}

ModelBussiness.prototype.showAllFloorOutLinesModel = function (callBack) {
    var _this = this;
    this.openFloors(function () {

        if (!_this.FloorLines) {
            var linesname = [];

            for (var i = 1; i <= 3; i++) {
                linesname.push("zb_f" + i + "_H1xi");
                linesname.push("zb_f" + i + "_H2xi");
                linesname.push("zb_f" + i + "_Ixi");
                linesname.push("zb_f" + i + "_H1cu");
                linesname.push("zb_f" + i + "_H2cu");
                linesname.push("zb_f" + i + "_Icu");
            }
            _this.FloorLines = WT3DObj.commonFunc.findObjectsByNames(linesname);
        }
        var outlines = [];
        if (_this.FloorLines.length > 0) {
            $.each(_this.FloorLines, function (_index, _obj) {

                if (_obj.name.indexOf("cu") >= 0) {
                    _obj.visible = true;
                    outlines.push(_obj);
                }
            });
        }
        var vmodes = [];
        $.each(WT3DObj.scene.children, function (_index, _obj) {
            if (_obj.name.indexOf("r1_11_1") >= 0 || _obj.name.indexOf("r1_11_2") >= 0 || _obj.name.indexOf("zb_f1_jigui") >= 0) {
                vmodes.push(_obj);
            }
        });
        vmodes = vmodes.concat(_this.FloorLines);
        _this.VitureAllFloors(function () {
            WT3DObj.commonFunc.changeObjsOpacity(vmodes, 0.1, 1, 100, function () {
                WT3DObj.commonFunc.changeObjsOpacity(outlines, 0.1, 1, 500, function () {
                    if (callBack) {
                        callBack();
                    }
                });
            });
        });
    })
}

9、设备检索，端口检索，能快速定位到具体设备。查看设备信息状态，位置信息等。

主要思路：

//搜索
ModelBussiness.prototype.showPostionState = false;
ModelBussiness.prototype.showPosition = function (cabid, serverid, portId) {
    var _this = this;
    if (window.location.href.indexOf("index.html") >= 0) {
        var serchParam = cabid + "_search_" + serverid;
        if (portId) {
            serchParam += "_search_" + portId;
        }
        _this.dbClickSelect(WT3DObj.commonFunc.findObject("build_1"),null, null, serchParam);
    }
    if (window.location.href.indexOf("floor.html")>=0) {
        WT3DObj.commonFunc.flashObjsGradualByName(["zb_3f1_546", "zb_3f2_1320"], "floor3_flash1", "000000", "0000ff", 7, 1000, 10, 0);
        setTimeout(function () {
            var serchParam = cabid + "_search_" + serverid;
            if (portId) {
                serchParam += "_search_" + portId;
            }
            _this.dbClickSelect(WT3DObj.commonFunc.findObject("zb_3f1_546"),null, null, serchParam);
        }, 2000);
    }
}
// 隐藏所有模型
ModelBussiness.prototype.cacheAllModels = function(cb){
    this.m_allNames=[].concat(this.m_yuanquNames,this.m_guandaoNames,this.m_xianlanNames,this.m_shenduNames,this.m_buildInfoNames)
    if(!this.m_allModels.length){
        var models=WT3DObj.scene.children
        for(var i=0;i<models.length;i++){
            var item=models[i];
            if(this.m_yuanquNames.indexOf(item.name)>-1){this.m_yuanquModels.push(item)}
            if(this.m_guandaoNames.indexOf(item.name)>-1){this.m_guandaoModels.push(item)}
            if(this.m_xianlanNames.indexOf(item.name)>-1){this.m_xianlanModels.push(item)}
            if(this.m_shenduNames.indexOf(item.name)>-1){this.m_shenduModels.push(item)}
            if(this.m_buildInfoNames.indexOf(item.name)>-1){this.m_buildInfoModels.push(item)}
        }
        this.m_allModels=[].concat(this.m_yuanquModels,this.m_guandaoModels,this.m_xianlanModels,this.m_shenduModels,this.m_buildInfoModels)
    }
}

10、电路检索，线缆中包含很多电路，支持电路检索，能快速定位相应的电路。

主要代码：

//隐藏显示线
ModelBussiness.prototype.Lines = null;
ModelBussiness.prototype.hideAllLinesModels = function (cb) {
    var _this = this;
    WT3DObj.commonFunc.changeObjsOpacity(this.m_xianlanModels, 1, 0.1, 500, function () {
        $.each(_this.m_xianlanModels, function (_index, _obj) {
            _obj.visible = false;
            _obj.position.y=-1000000;
        });
        cb&&cb()
    });
}
ModelBussiness.prototype.showAllLineModels = function (cb) {
    var line = [];
    $.each(this.m_xianlanModels, function (_index, _obj) {
        _obj.visible = true;
        _obj.position.y=0;
        if (_obj.name.indexOf("cuxian")>0) {
            line.push(_obj);
        }
    })
    WT3DObj.commonFunc.changeObjsOpacity(this.m_xianlanModels, 0.1, 1, 500, function () {
        // WT3DObj.commonFunc.changeObjsOpacity(line, 1, 1, 500, function () {
            cb&&cb()
        // });
    });
}
ModelBussiness.prototype.showLines = function(callback){
    var guandao=WT3DObj.commonFunc.findObject('yqgx_guandao');
    var backGround=WT3DObj.commonFunc.findObject('backGround');
    guandao.position.y=-1000000;
    backGround.position.y=-1000000;
    $.each(this.m_xianlanModels, function (_index, _obj) {
        _obj.visible = true;
        if (_obj.name.indexOf("cuxian")>0) {
            _obj.position.y=0;
            // if(_obj.resourcePosition){
            //     _obj.position.y=_obj.resourcePosition.y;
            // }
        }
    })
    WT3DObj.commonFunc.changeObjsOpacity(this.m_xianlanModels, 0.1, 1, 500, function () {
    });
}
//虚化某一根线
ModelBussiness.prototype.visLine = function (name, callBack) {
    if (!this.Lines) {
        this.Lines = WT3DObj.commonFunc.findObjectsByNames(
            ["yqgx_cuxian1_11", "yqgx_cuxian2_15", "yqgx_cuxian3_19", "yqgx_cuxian4_23", "yqgx_cuxian5_27", "yqgx_cuxian6_31", "yqgx_cuxian7_35", "yqgx_cuxian8_39", "yqgx_cuxian9_46", "yqgx_cuxian10_50", "yqgx_xixian1_54", "yqgx_xixian2_54", "yqgx_xixian3_62", "yqgx_xixian4_66", "yqgx_xixian5_70", "yqgx_xixian6_72", "yqgx_xixian7_76", "yqgx_xixian8_80", "yqgx_xixian9_86", "yqgx_xixian10_92"]);
    }
    var line = [];
    $.each(this.Lines, function (_index, _obj) {
        if (_obj.name == name) {
            line.push(_obj);
        }
    })
    WT3DObj.commonFunc.changeObjsOpacity(line,1, 0.5, 500, function () {
        if (callBack) {
            callBack();
        }
    });
}
//显示单根线
ModelBussiness.prototype.showSingleLines = function (name,callBack) {
    if (!this.Lines) {
        this.Lines = WT3DObj.commonFunc.findObjectsByNames(
            ["yqgx_cuxian1_11", "yqgx_cuxian2_15", "yqgx_cuxian3_19", "yqgx_cuxian4_23", "yqgx_cuxian5_27", "yqgx_cuxian6_31", "yqgx_cuxian7_35", "yqgx_cuxian8_39", "yqgx_cuxian9_46", "yqgx_cuxian10_50", "yqgx_xixian1_54", "yqgx_xixian2_54", "yqgx_xixian3_62", "yqgx_xixian4_66", "yqgx_xixian5_70", "yqgx_xixian6_72", "yqgx_xixian7_76", "yqgx_xixian8_80", "yqgx_xixian9_86", "yqgx_xixian10_92"]);
    }
    var line = [];
    $.each(this.Lines, function (_index, _obj) {
        _obj.position.y=-1000000;
        if (_obj.name == name) {
            line.push(_obj);
            _obj.visible = true;
            _obj.position.y=0;
        }
    })
    WT3DObj.commonFunc.changeObjsOpacity(line, 0.3, 1, 500, function () {
        if (callBack) {
            callBack();
        }
    });
}
