添加实体
const viewer = new Cesium.Viewer('cesiumContainer', {})
viewer.entities.add()
查看实体
const viewer = new Cesium.Viewer('cesiumContainer', {})
const billboard = viewer.entities.add({...})
viewer.zoomTo(billboard)
删除实体
根据实体删除
if (billboard.value) {
viewer.value?.entities.remove(billboard.value)
}
根据实体 id 删除
if (billboard.value) {
viewer.value?.entities.removeById('video')
}
删除所有实体
viewer.value?.entities.removeAll()
cesium 绘制标记实体

监听鼠标左键事件
const handler = new Cesium.ScreenSpaceEventHandler(viewer.value.scene.canvas)
handler.setInputAction(function (mouse: Cesium.ScreenSpaceEventHandler.PositionedEvent) {
var pick = viewer.value?.scene.pick(mouse.position)

当点击标记会把相应的属性返回
