在哥伦布视图中如何使用 LookAt 查看一组坐标?此方法适用于 3d 或全球视图,但在哥伦布视图中,坐标不能正确转换,因为它应该将我发送到美国,但实际上将我发送到非洲海岸。我怎样才能让它在哥伦布视图中工作?

可以在这里重新创建问题 https://cesiumjs.org/Cesium/Apps/Sandcastle/index.html

var viewer = new Cesium.Viewer('cesiumContainer', {
        sceneMode: Cesium.SceneMode.COLUMBUS_VIEW,
//Hide the base layer picker
baseLayerPicker : false,
//Use BingMaps
imageryProvider : new Cesium.BingMapsImageryProvider({
        url: '//dev.virtualearth.net',
        mapStyle: Cesium.BingMapsStyle.ROAD
    })
    });
var scene = viewer.scene;
Sandcastle.addDefaultToolbarButton('test', function() {
var center = Cesium.Cartesian3.fromDegrees(-111, 41);
var transform = Cesium.Transforms.eastNorthUpToFixedFrame(center);

// View in east-north-up frame
var camera = scene.camera;
Cesium.Matrix4.clone(transform, camera.transform);
camera.constrainedAxis = Cesium.Cartesian3.UNIT_Z;

// Zoom in
camera.lookAt(
    new Cesium.Cartesian3(-120000.0, -120000.0, 120000.0),
    Cesium.Cartesian3.ZERO,
    Cesium.Cartesian3.UNIT_Z);
});

固定视图有效,但我的视图是固定的:

var viewer = new Cesium.Viewer('cesiumContainer', {
        sceneMode: Cesium.SceneMode.COLUMBUS_VIEW,
//Hide the base layer picker
baseLayerPicker : false,
//Use BingMaps
imageryProvider : new Cesium.BingMapsImageryProvider({
        url: '//dev.virtualearth.net',
        mapStyle: Cesium.BingMapsStyle.ROAD
    })
    });
var scene = viewer.scene;
Sandcastle.addDefaultToolbarButton('test', function() {
var center = Cesium.Cartesian3.fromDegrees(-111, 41);
var transform = Cesium.Transforms.eastNorthUpToFixedFrame(center);

// View in east-north-up frame
var camera = scene.camera;
Cesium.Matrix4.clone(transform, camera.transform);
camera.constrainedAxis = Cesium.Cartesian3.UNIT_Z;

// Zoom in
camera.lookAt(
    new Cesium.Cartesian3(-120000.0, -120000.0, 120000.0),
    Cesium.Cartesian3.ZERO,
    Cesium.Cartesian3.UNIT_Z);
});

这看起来像一个错误。我在这里提交了一个问题。您可以同时尝试的一件事是使用Camera.flyTo持续时间为 0。
