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：

如果你有什么要交流的心得 可邮件我
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 }];

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 }) } else { 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": 6543871, "materialType": "Phong", "side": 1, "opacity": 0.6 }, "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(); } }); }
