# 三维标签(Marker3D)

上一节 (opens new window),我们实现了在场景中添加二维自定义标签的功能。这一节,我们来给场景添加一个三维标签作为报警点。

关于二维与三维标签的区别,可参见上一节 (opens new window)“二维标签与三维标签”中的内容。

# 教程内容

在已搭建的运维平台上,接下来我们需要

  • 通过按钮添加三维标签
  • 为三维标签添加onClick效果

# 三维标签

# 1. 创建三维标签

我们先创建一个放置标签的按钮:

<button class="button" id="btnAddMarker" onclick="addMarker()">放置三维标签</button>

接下来,我们要在一个指定的坐标点添加三维标签。

与二维标签相似,在构造三维标签实例之前,我们先要构造一个存放三维标签的容器,并完成对容器的配置。

// ************************** 内建三维标签 **************************
let is3DMarkerPlaced = false;
function addMarker() {
  if (is3DMarkerPlaced) {
    return;
  }
  // 构造三维标签容器配置markerContainerConfig
  let markerContainerConfig = new Glodon.Bimface.Plugins.Marker3D.Marker3DContainerConfig();
  // 设置markerContainerConfig匹配的viewer对象
  markerContainerConfig.viewer = viewer3D;
  // 构造三维标签容器markerContainer
  let markerContainer = new Glodon.Bimface.Plugins.Marker3D.Marker3DContainer(markerContainerConfig);
}

创建完markerContainer后,我们需要继续构造一个三维标签对象,并完成对它的配置。

其中,我们手动构造了三维标签的点位,你也可以通过鼠标点击的方式来拾取点位,与二维标签 (opens new window)的实现方法相同。

// 构造三维标签配置项
let markerConfig = new Glodon.Bimface.Plugins.Marker3D.Marker3DConfig();
// 为标签指定图片路径
markerConfig.src = "http://static.bimface.com/resources/3DMarker/warner/warner_red.png";
// 构造点位,并指定为标签的插入点
let markerPos = {"x": -5743.838548165086, "y": -1667.12605781937, "z": 12923.137945446013};
markerConfig.worldPosition = markerPos;
// 指定标签大小
markerConfig.size = 60;
// 构造三维标签
let marker = new Glodon.Bimface.Plugins.Marker3D.Marker3D(markerConfig);
// 将三维标签添加至容器内
markerContainer.addItem(marker);
is3DMarkerPlaced = true;

现在,我们已经能够向场景中的指定位置添加三维标签了。

三维标签

# 2. 添加onClick效果

最后,我们为三维标签添加一个onClick效果,触发后浏览器会跳出弹窗,提醒用户这是一个警告。

在addMarker内增加如下代码

// 添加标签的点击事件
marker.onClick(function() {
  window.alert('Warning!');
});

重新加载页面并点击三维标签后,我们会发现弹出了写有“Warning!”的窗口。

三维标签点击示例
