// 创建 Cesium Viewer
var viewer = new Cesium.Viewer('cesiumContainer');
// 设置 home 键
viewer.homeButton.viewModel.command = function() {// 设置相机位置viewer.camera.setView({destination: Cesium.Cartesian3.fromDegrees(120.678594, 24.803711, 1000),orientation: {heading: Cesium.Math.toRadians(0),pitch: Cesium.Math.toRadians(-30),roll: 0.0}});
};
