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,

                    // 此处设置双击聚焦  
                    {  
                        modelBussiness.dbClickSelect(\_obj, face);  
                        if (\_obj.name.indexOf("build") == 0 || \_obj.name.indexOf("ecn") == 0) {

                    }

              }  
          },  
        \],  
        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) {

                    }  
                });  
            }  
        })  
            .fail(function () {

                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 }];

    $.each(param.builds, function (\_index, \_obj) {  
        for (var i = 1; i <= \_obj.floors; i++) {

                    points.push(\_sobj);

}

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-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();
}
});
}
