基于WebGL架构的3D可视化平台—新风体系演示

2019年8月20日 147次阅读来源: ThingJS

新风体系是依据在密闭的室内一侧用专用装备向室内送新风，再从另一侧由专用装备向室外排挤，在室内会构成“新风活动场”，从而满足室内新风换气的须要。实施方案是：采纳高风压、大流量风机、依托机器强力由一侧向室内送风，由另一侧用特地设想的排风风机向室外排挤的体式格局强迫在体系内构成新风活动场。在送风的同时对进入室内的氛围进过滤、消毒、杀菌、增氧、预热（冬季）。

接下来就用ThingJs平台来搭建一个新风体系

第一步，应用CampusBuilder搭建模仿场景。CampusBuilder的模子库有林林总总的模子，使我们搭建出的场景更传神。
《基于WebGL架构的3D可视化平台—新风体系演示》

//加载场景代码
var app = new THING.App({
    // 场景地点
    "url": "http://www.thingjs.com/./uploads/wechat/oLX7p05lsWJZUIxnIWsNXAzJ40X8/scene/新风演示2",

});

第二步，建立三个数组来保留每一个风的模子。、

var hotWindGroup = [];
var coolWindGroup = [];
var newWindGroup = [];
var wind = null;

第三步，组织一个建立风的函数，为了轻易建立风及其位置，我们拔取排风装备为风的父物体，将建立出来的风的visiable属性设置为false（这里这个坐标题目能够看一下官网的教程中掌握物体中的坐标转换）。

function createWind(parent, x, y, angle, localPosition, color, group) {
    rs = app.query(parent)[0];
    wind = app.create({
        type: 'Thing',
        name: 'hotWind',
        url: 'http://model.3dmomoda.cn/models/4da706d8a37047298c0318a5b9546abd/0/gltf/',
        localPosition: localPosition,
        scale: [1, 2, 1],
        angle: angle,
        parent: rs,
    });
    wind.style.color = color;
    wind.visible = false;
    wind.rotateX(x);
    wind.rotateY(y);
    group.push(wind);
}

第四步，最先建立风模子，并调解一下摄像机的角度及位置。

app.on('load', function () {
    //摄像机角度
    app.camera.position = [-22.91452445633646, 30.46296743148116, -23.83548169673341];
    app.camera.target = [-13.532807014407252, 5.6565539015865856, -3.3431546399681276];
    //hotWind
    createWind('空调1', 0, 0, 0, [0, -2, 0], '#FF0000', hotWindGroup);
    createWind('空调1', 0, 0, 0, [0, -2, 0.5], '#FF0000', hotWindGroup);
    createWind('空调1', 0, 0, 0, [0, -2, 1], '#FF0000', hotWindGroup);
    createWind('空调2', 0, 0, 0, [0, -2, 0], '#FF0000', hotWindGroup);
    createWind('空调2', 0, 0, 0, [0, -2, 0.5], '#FF0000', hotWindGroup);
    createWind('空调2', 0, 0, 0, [0, -2, 1], '#FF0000', hotWindGroup);
    //coolWind
    createWind('空调1', 0, 0, 0, [0, -2, 0], '#0000FF', coolWindGroup);
    createWind('空调1', 0, 0, 0, [0, -2, 0.5], '#0000FF', coolWindGroup);
    createWind('空调1', 0, 0, 0, [0, -2, 1], '#0000FF', coolWindGroup);
    createWind('空调2', 0, 0, 0, [0, -2, 0], '#0000FF', coolWindGroup);
    createWind('空调2', 0, 0, 0, [0, -2, 0.5], '#0000FF', coolWindGroup);
    createWind('空调2', 0, 0, 0, [0, -2, 1], '#0000FF', coolWindGroup);
    //newWind
    createWind('排风1', -50, 0, 0, [0, -0.5, 2], '#00FF00', newWindGroup);
    createWind('排风1', -50, 0, 0, [0, -0.5, 4], '#00FF00', newWindGroup);
    createWind('排风1', -50, 0, 0, [0, -0.5, 6], '#00FF00', newWindGroup);
    createWind('排风1', -50, 50, 50, [2, -0.5, 7], '#00FF00', newWindGroup);
    createWind('排风1', -50, 50, 50, [4, -0.5, 8], '#00FF00', newWindGroup);
    createWind('排风1', -50, 50, 50, [6, -0.5, 9], '#00FF00', newWindGroup);
    createWind('排风1', -50, 50, 50, [8, -0.5, 12], '#00FF00', newWindGroup);
    createWind('排风1', -50, 50, 50, [10, -0.5, 15], '#00FF00', newWindGroup);
    createWind('排风1', -50, 50, 50, [12, -0.5, 18], '#00FF00', newWindGroup);
    createWind('排风1', -50, 50, 50, [10, -0.5, 9], '#00FF00', newWindGroup);
    createWind('排风1', -50, 50, 50, [14, -0.5, 9], '#00FF00', newWindGroup);
    createWind('排风1', -50, 50, 50, [18, -0.5, 9], '#00FF00', newWindGroup);
    createWind('排风1', -50, 50, 50, [22, -0.5, 9], '#00FF00', newWindGroup);
    createWind('排风1', -50, 50, 50, [26, -0.5, 9], '#00FF00', newWindGroup);
    createWind('排风2', -50, 0, 0, [0, -0.5, 2], '#00FF00', newWindGroup);
    createWind('排风3', -50, 0, 0, [0, -0.5, 2], '#00FF00', newWindGroup);
    createWind('排风4', -50, 0, 0, [0, -0.5, 2], '#00FF00', newWindGroup);

            newWindGroup[i].visible = true;
            newWindGroup[i].moveTo({
                "time": 4000,
                "position": newWindGroup[i+1].position,
            });
        }
});

第五步，运转项目。演示地点

思索与总结：

起首就是空间坐标系下转父物体坐标真是弄晕了，看了官网的教程若干理解了一点。刚最先的时刻我一向以为我的子物体以父物体坐标下安排的时刻，子物体坐标轴的题目指向的题目。看了教程发明本身的忧郁过剩了，就好像是人戴鸭舌帽帽子不论戴在谁的头上都一样。

其次就是让风动起来，最初是想让一个模子在空间中活动，发明结果不好用。末了就建立了多个模子他们对应着有各自的点，让每一个模子向他下一个模子的位置挪动完成活动。
