序：

　　还是要抽出时间看书的，迷上了豆豆的作品，最近在看《天幕红尘》，书中主人公的人生价值观以及修为都是让我惊为叹止。很想成为那样的人，但是再看看自己每天干的事，与时间的支配情况，真是十分的汗颜。除了为了生活所必须的工作时间外，还有大部分零散的时间不是给了短视频，就是给了短讯文章，简讯媒介，不说是毫无意义吧，但也着实是浮躁虚夸了。

　　用豆豆作品里的话术，"透视社会依次有三个层面：技术、制度和文化。小到一个人，大到一个国家一个民族，任何一种命运归根到底都是那种文化属性的产物"。我终究是干技术的，还是无法洞察其中奥义，只是熟悉了几门糊口的技巧而已，究竟其本质便无所得之了，或者说依然没找到那安身立命的意义。长路漫漫，且寻着吧。人生也许也像某个技术门类，需要不断的回顾，记录，总结。才能真正发现一些实质性的东西。究竟涅槃，如来？

　　本想谈技术，话题终究是扯远了，但总归要扯点啥吧，练练文笔也好，述述心态也罢，反正也少有人看写在前面的废话，这任算是，无伤技术之大雅，无关文章之紧要了。

　　还是闲话少序，切入正题吧。

前言：

　　前面的课程介绍过定位相关的技术解决方案，《webgl(three.js)实现室内定位,楼宇bim、实时定位三维可视化解决方案——第五课》，从硬件到可视化，都已经比较全面的讲述了一遍,这边文章相当于那篇文件的一个改进版本，主要是在可视化呈现方面，根据具体的实施项目，在可视化方面做一个比较全面的技术剖析。

关于硬件采集端技术，因为精度要求不高，任然采用的是：低功耗有源RFID+读卡器基地器+智能分析。

关于室内定位市场前景，那篇文章也做了一些分析，这里不做赘述。

一、整体效果

还是先看整体效果，再探具体实现技术的究竟

上图展示整体园区以及周边的科技感效果。

上图展示近距离整体园区建设风貌。

二、功能展示

2.1、展开楼层

楼层展开实现比较简单，首先再建模的时候讲究分离模型，不能讲楼层内部，楼层外墙一股脑做成一个模型，需要讲模型分解，分开建模，

实现楼层展开就比较方便了，只需要控制外墙模型隐藏，然后控制每个楼层的的高度位置就可以。

实现代码如下：

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(["wjwb1_232", "wjwbuilds_55"]);

    //隐藏大楼

    WT3DObj.commonFunc.setSkinColorByname("wjwb1_232", 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("wjwb1_232");

            if (typeof (_obj.oldPositionY) == 'undefined') {

                _obj.oldPositionY = _obj.position.y

            }

            _obj.position.y = 1000000;

            _obj.visible = false;

        WT3DObj.commonFunc.changeCameraPosition({ x: 3247.2796000738454, y: 2191.5405041410445, z: 5229.077446579187 }, { x: 2719.261239206996, y: 80.49406057323252, z: 3015.8739289848077 }, 500,

            function () { });

        var names = ["floor_1", "floor_2", "floor_3", "floor_4", "floor_5", "floor_6"];

        var floors = WT3DObj.commonFunc.findObjectsByNames(names);

        modelBussiness.openFloors(floors, function () {

            if (callBack) {

                callBack();

            }

        });

    });

}

//隐藏楼层内部情况

ModelBussiness.prototype.hideBuildFloors = function (buildnub, callBack) {

    var _this = this

    _this.showFloorState = "close";

    var names = ["floor_1", "floor_2", "floor_3", "floor_4", "floor_5", "floor_6"];

    var builds = WT3DObj.commonFunc.findObjectsByNames(["wjwb1_232", "wjwbuilds_55"]);

    var floors = WT3DObj.commonFunc.findObjectsByNames(names);

    this.closeFloors(floors, function () {

        $.each(builds, function (_index, _obj) {

            if (typeof (_obj.oldPositionY) == 'undefined') {

                _obj.oldPositionY = _obj.position.y

            }

            _obj.position.y = _obj.oldPositionY;

            _obj.visible = true;

        })

        WT3DModel.commonFunc.changeObjsOpacity(builds, 0, 1, 1000, function (obj) {

            WT3DObj.commonFunc.setSkinColorByname("wjwb1_232", 0x000000);

        });

        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("_")[1]);

        height = (floor - 1) * 300 +50;

        new Tn(_obj.position).to({//补充间隔动画

            y: height

        }, 500).start();

        });

        setTimeout(function () {

        if (callBack) {

            callBack()

        }

        },600);

    }, 500)

}

2.2、绘制定位路径

绘制定位路径，相比楼层展开要复杂一些，这里要用到定位设备与虚拟模型之间的关联与绑定，然后标记跟着模型运动

主要分为以下几步：

　　第一、建模

　　第二、建立虚拟模型，绑定设备id

　　第三、数据id转换为模型id

　　第四、寻址，找到对应的虚拟模型列表、并且获取各自位置

　　第五、根据位置画线、移动标签

三、具体实现

3.1、创建周遭环境模型，特效模型等

建模代码如下：

[{"show":true,"uuid":"","name":"cube2_6","objType":"cube2","length":200,"width":200,"height":200,"x":0,"y":200,"z":0,"style":{"skinColor":16777215,"skin":{"skin_up":{"skinColor":16777215,"imgurl":"../../img/3dImg/rack_inside.jpg","materialType":"basic","side":1,"opacity":1},"skin_down":{"skinColor":16777215},"skin_fore":{"skinColor":16777215},"skin_behind":{"skinColor":16777215},"skin_left":{"skinColor":16777215},"skin_right":{"skinColor":16777215}}},"showSortNub":6},{"show":true,"uuid":"","name":"wjwbuilds_270","objType":"GroupObj","scale":{"x":1,"y":1,"z":1},"position":{"x":0,"y":0,"z":0},"rotation":[{"direction":"x","degree":0}],"modelGroupName":"wjwbuilds","modelSrc":"../js/msj3D/sourse/customModels/models/wjwbuilds.json?v1.50.4428873971970626","srcType":"filePath","showSortNub":270}]

3.2、创建外墙模型

单独创建需要裂解的大楼外墙模型，具体如下：

[{"show":true,"uuid":"","name":"cube2_6","objType":"cube2","length":200,"width":200,"height":200,"x":0,"y":200,"z":0,"style":{"skinColor":16777215,"skin":{"skin_up":{"skinColor":16777215,"imgurl":"../../img/3dImg/rack_inside.jpg","materialType":"basic","side":1,"opacity":1},"skin_down":{"skinColor":16777215},"skin_fore":{"skinColor":16777215},"skin_behind":{"skinColor":16777215},"skin_left":{"skinColor":16777215},"skin_right":{"skinColor":16777215}}},"showSortNub":6},{"show":true,"uuid":"","name":"wjwb1_7","objType":"GroupObj","scale":{"x":1,"y":1,"z":1},"position":{"x":0,"y":0,"z":0},"rotation":[{"direction":"x","degree":0}],"modelGroupName":"wjwb1","modelSrc":"../js/msj3D/sourse/customModels/models/wjwb1.json?v1.50.7245325959034448","srcType":"filePath","showSortNub":7}]

3.3、其它细节楼宇模型

作为辅助美观模型，单独创建模型如下：

[{"show":true,"uuid":"","name":"wjwb2_38","objType":"GroupObj","scale":{"x":1,"y":1,"z":1},"position":{"x":0,"y":0,"z":0},"rotation":[{"direction":"x","degree":0}],"modelGroupName":"wjwb2","modelSrc":"../js/msj3D/sourse/customModels/models/wjwb2.json?v1.50.2327047742615571","srcType":"filePath","showSortNub":38}]

3.4、楼层模型

各楼层模型单独创建，便于控制与展示

[{"show":true,"uuid":"","name":"wjwf1_40","objType":"GroupObj","scale":{"x":1,"y":1,"z":1},"position":{"x":0,"y":0,"z":0},"rotation":[{"direction":"x","degree":0}],"modelGroupName":"wjwf1","modelSrc":"../js/msj3D/sourse/customModels/models/wjwf1.json?v1.50.13740666293081194","srcType":"filePath","showSortNub":40}]

多角度观察一下楼层模型：

四、定位详解

本想放到第三章一起讲解，但这部分实现比较重要，所以单独一章讲解

如上图，粉色的点位表示房间门内的辅助点，亮绿色的点位表示设备所对应的门外辅助点

我们这里只需要绑定门外的辅助点到对应的设备就可以

当再某处停留事件过长，我们通常判断已经进入房间，直接讲门外门内两个点链接，即可。

4.1、存储虚拟点位

//使用二叉树储存法，将辅助点与设备id进行绑定。

4.2、具体实现画线定位

实现画线定位是利用设备id找到对应辅助点，然后将辅助点链接起来的方式

定位标签移动，使用补间动画移动效果即可。

//显示路径

function drawLineFunc(floor, start, end, timeLong, startOut, endIn) {

    //drawLineDataList.push({

    //    floor: 楼层,

    //    start: 开始设备点id,

    //    end: 结束设备点id,

    //    timeLong: 移动时长,

    //    startOut: 是否是从房间里出来,

    //    endIn: 是否进入房间

    //});

    WT3DObj.commonFunc.changeCameraPosition(ConfigData["f" + floor].cp, ConfigData["f" + floor].ct, 300,

        function () { });

    //生成路径节点数组

    var startindex = -1;

    var startindex2 = -1;

    var endindex = -1;

    var endindex2 =-1;

    var linedata = ConfigData["f" + floor].line;

    $.each(linedata, function (_index, _obj) {

        if (_obj instanceof Array) {

            $.each(_obj, function (_cindex, _cobj) {

                if (_cobj + "" == start + "") {

                    startindex = _index;

                    startindex2 = _cindex;

                }

                if (_cobj + "" == end + "") {

                    endindex = _index;

                    endindex2 = _cindex;

                }

            })

        } else {
