2：初始化镜头（飞行到某个位置）
viewer.camera.flyTo({
destination: Cesium.Cartesian3.fromDegrees(121.479802, 31.225271, 5000.0)
});
3：对地图进行一些操作设置
//设置中键放大缩小
viewer.scene.screenSpaceCameraController.zoomEventTypes = [
Cesium.CameraEventType.WHEEL,
Cesium.CameraEventType.MIDDLE_DRAG,
Cesium.CameraEventType.PINCH
];
//设置右键旋转
viewer.scene.screenSpaceCameraController.tiltEventTypes = [
Cesium.CameraEventType.RIGHT_DRAG,
Cesium.CameraEventType.PINCH,
{
eventType: Cesium.CameraEventType.RIGHT_DRAG,
modifier: Cesium.KeyboardEventModifier.CTRL
},
{
eventType: Cesium.CameraEventType.MIDDLE_DRAG,
modifier: Cesium.KeyboardEventModifier.CTRL
}
];
4：注册场景点击事件
// 事件绑定
handler.setInputAction(function(movement) {
// 返回地图表面上的点在世界坐标系中
let cartesian1 = viewer.camera.pickEllipsoid(movement.position, viewer.scene.globe.ellipsoid);
// 将世界坐标转换为经纬度
let cartographic1 = viewer.scene.globe.ellipsoid.cartesianToCartographic(cartesian1);
let lon1 = Cesium.Math.toDegrees(cartographic1.longitude); //经度值
let lat1 = Cesium.Math.toDegrees(cartographic1.latitude); //纬度值
}, Cesium.ScreenSpaceEventType.RIGHT_CLICK)
