SelectionIndicatorViewModel

SelectionIndicatorViewModel是一个控件视图模型,用于在Cesium中显示一个选择指示器。选择指示器是在相机场景中显示一个虚线框,用于表示当前选择的实体或位置。

构造函数

SelectionIndicatorViewModel(viewer) - 构造函数需要传入Cesium的Viewer对象。

属性

currentViewer - 获取或设置要渲染的Cesium视图器。

isDestroyed - 获取指示此对象是否已销毁。

container - 获取或设置选择指示器在DOM中的容器元素。

viewModel - 获取选择指示器的视图模型对象。

视图模型属性

show - 获取或设置选择指示器是否可见。

highlightedObject - 获取或设置当前高亮显示的实体对象。

position - 获取或设置当前的位置,如果设置了位置,该位置会被高亮显示。

方法

destroy() - 销毁选择指示器及其关联的资源。

isDestroyed() - 获取指示此对象是否已销毁。

事件

changed - 可见性或高亮对象更改时触发。

示例

var viewer = new Cesium.Viewer('cesiumContainer');
var selectionIndicatorViewModel = new Cesium.SelectionIndicatorViewModel(viewer);

selectionIndicatorViewModel.viewModel.highlightedObjectChanged.addEventListener(function() {
    var entity = selectionIndicatorViewModel.viewModel.highlightedObject;
    console.log('Highlighted entity:', entity);
});

selectionIndicatorViewModel.viewModel.position = new Cesium.Cartesian3(100000.0, 0.0, 0.0);
selectionIndicatorViewModel.viewModel.show = true;

结论

Cesium SelectionIndicatorViewModel提供了一个简单的方式来高亮显示实体和位置,帮助用户在场景中选择正确的实体。这个控件可以作为Cesium中的一个有用的交互性质的组成部分。
