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：

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。

if(_obj.name.indexOf('jing_line_')>-1){//线缆
$("#guangLan").hide()
_this.inVisibleJing(function () {

})
}
}
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 () {

})
}

//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;

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 () {

}
//隐藏管道
ModelBussiness.prototype.hideGD = function (cb) {

guandao.visible = false;
cb&&cb()
});
}

// 显示深度
ModelBussiness.prototype.showDeep=function(cb){
modelBussiness.showDistance()
// 缓存相机位置

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();
}
});
}
