ModelVisualizer

ModelVisualizer是Cesium中的一个类,用于将模型加载到场景中。该类包含以下方法:

构造函数:

ModelVisualizer(scene, entityCollection)

参数说明:

  • scene:Cesium.Scene对象,场景对象
  • entityCollection:Cesium.EntityCollection对象,实体集合对象

方法:

showAllModels()

显示所有模型。

hideAllModels()

隐藏所有模型。

showModel(entity)

显示指定实体的模型。

参数说明:

  • entity:Cesium.Entity对象,实体对象
hideModel(entity)

隐藏指定实体的模型。

参数说明:

  • entity:Cesium.Entity对象,实体对象
getModel(entity)

获取指定实体的模型。

参数说明:

  • entity:Cesium.Entity对象,实体对象

返回值:

  • Cesium.Model对象,模型对象
createModel(entity)

创建指定实体的模型。

参数说明:

  • entity:Cesium.Entity对象,实体对象
destroyModel(entity)

销毁指定实体的模型。

参数说明:

  • entity:Cesium.Entity对象,实体对象
update()

更新场景中所有模型的状态。

updateModel(entity)

更新指定实体的模型的状态。

参数说明:

  • entity:Cesium.Entity对象,实体对象
getBoundingSphere(entity)

获取指定实体的模型的包围球。

参数说明:

  • entity:Cesium.Entity对象,实体对象

返回值:

  • Cesium.BoundingSphere对象,包围球对象
getBoundingSphereArray(entities)

获取指定实体数组的模型的包围球数组。

参数说明:

  • entities:Cesium.Entity数组,实体数组

返回值:

  • Cesium.BoundingSphere数组,包围球数组
isDestroyed()

判断是否已销毁。

返回值:

  • boolean,true表示已销毁,false表示未销毁。
destroy()

销毁该对象,释放内存。

示例:

var viewer = new Cesium.Viewer('cesiumContainer');
var scene = viewer.scene;
var entityCollection = new Cesium.EntityCollection();
var visualizer = new Cesium.ModelVisualizer(scene, entityCollection);

var entity = entityCollection.add({
    position: Cesium.Cartesian3.fromDegrees(-122.0, 45.0),
    model: {
        uri: 'url/to/model.gltf'
    }
});

visualizer.showModel(entity);

以上示例代码创建了一个模型可视化器对象,将模型实体添加到实体集合中,并通过showModel方法显示了该模型实体的模型。
