隨着社會的發展，城市中的汽車愈來愈多。車輛集中存放管理的場所被人類提出車輛進出的秩序、車輛存放的安全性、車輛存放管理的有償性等要求。停車場系統應用現代機械電子及通信科學技術，集控制硬件、軟件於一體。隨着科技的發展，停車場管理系統也突飛猛進，目前最爲專業化的停車場系統爲免取卡停車場。下面咱們就用ThingJs平臺來搭建一個3d可視化的停車場管理系統。
第一步，仍是用CampusBuilder來搭建一個模擬停車場。CampusBuider很好用在以往的文章中也屢次說起過，豐富的模型庫任你選擇快速搭建3D場景。

第二步，初始化攝像機的位置並添加鼠標滑過，左鍵單擊，右鍵單擊，左鍵雙擊等事件。鼠標滑過，車勾邊變紅色，車位勾邊邊藍色。左鍵單擊，車或車位彈出信息牌。右鍵單擊，關閉當前信息牌，鏡頭初始化。getCarData() 與 getParkData() 爲模擬數據，沒有幾個售出的車位和車就用了switch。html

app.on('load', function (evt) {

    //初始化攝像機
    init_camera();

    //滑過勾邊
    var campus = evt.campus;
    var objs = app.query('.Building').add(campus.things);
    objs.on('mouseon', function (ev) {
        if (ev.object.name.search("car") == 0) {
            this.style.outlineColor = '#ff0000';
        }
        if (ev.object.name.search("park") == 0) {
            this.style.outlineColor = '#0000ff';
        }
    });
    objs.on('mouseoff', function () {
        this.style.outlineColor = null;
    });

    //單擊事件
    app.on('click', function (ev) {
        if (ev.button == 2) {
            destroy_ui();
            init_camera();
        }
        if (ev.object.name.search("car") == 0) {
            destroy_ui();
            getCarData(ev.object);
            create_ui_car();
        }
        if (ev.object.name.search("park") == 0) {
            destroy_ui();
            getParkData(ev.object);
            create_ui_park();
        }
    });

    //雙擊事件
    app.on('dblclick', function (ev) {

        if (ev.object.name.search("car") == 0) {
            app.camera.flyTo({

能按鈕，同時建立閘門管理子面板。
//主面板
var toolbar = new THING.widget.Panel({ width: '163px' });
var mainDataObj = {
    spaceStatistics: false,
    gateManagement: false,
    video: false,
    registrationForm: false
}

//閘門管理面板
var gateToolbar = new THING.widget.Panel({ width: '163px' });
gateToolbar.position = [450, 0];
gateToolbar.visible = false;
var gateDataObj = {
    entrance: false,
    exit: false,
}

//面板按鈕組件及事件
Loader.sync(['lib/iconfont.js'], function () {
    //主面板
    var button0 = toolbar.addImageBoolean(mainDataObj, 'spaceStatistics').caption('空間統計').url('#momoda_lc-icontubiao');
    var button1 = toolbar.addImageBoolean(mainDataObj, 'gateManagement').caption('閘門管理').url('#momoda_lc-icontubiao21');
