Cesium

heading （方位角），pitch （倾角），roll（旋转角）， range（距离中心距离）

let opt = {position: [117.74447781803329, 30.663937066156883, 225.23452906567712],heading: 4.7124621698699425,pitch: -0.17465633785744084,roll: 6.283185197024551,duration:5};
let entity = new Cesium.Entity({name: "飞行",position: Cesium.Cartesian3.fromDegrees(opt.position[0],opt.position[1],opt.position[2]),point: {pixelSize: 10,color: Cesium.Color.WHITE.withAlpha(0),outlineColor: Cesium.Color.WHITE.withAlpha(0),outlineWidth: 0}});
viewer.entities.add(entity);

1.viewer.zoomTo

       viewer.zoomTo(entity ,{heading:opt.heading,pitch:opt.pitch,range:opt.range})//或者 viewer.zoomTo(viewer.entities)

2.viewer.flyTo

 viewer.flyTo(entity, {offset: {heading: opt.heading,pitch:opt.pitch,roll: opt.roll},duration: opt.duration // 设置飞行持续时间，默认会根据距离来计算}).then(e => {func & func();});

3.viewer.camera.flyTo
viewer.camera.flyTo 也是通过动画的方式转移到某个位置， 参数比viewer.flyTo要多

viewer.camera.flyTo({destination: Cesium.Cartesian3.fromDegrees(107.0, 40.0, 5000000), //摄像机的最终位置duration: 3,                           //飞行所用时间maximumHeight: 20000,                  //飞行高峰时的最大高度。pitchAdjustHeight: 1500,               //如果摄像机的飞行高于此值，请调整俯仰航向以降低俯仰，并将地球保持在视野中orientation: {heading: opt.heading, //方位角pitch: opt.pitch,  //倾角roll: opt.roll     //旋转角}});

4.viewer.camera.lookAt
立即定位到某个位置， 而且相机锁住此位置。

var center = Cesium.Cartesian3.fromDegrees(-107,40,0)//目标位置viewer.camera.lookAt(center, new Cesium.Cartesian3(x,x,x);//三个参数数字分别是：方位角，倾角，俯角

5.viewer.camera.setView
将摄像机定位到某个位置

viewer.camera.setView({destination : Cesium.Cartesian3.fromDegrees(107.0, 40.0, 5000000),//相机位置orientation: {heading :opt.heading, //方位角pitch : opt.pitch, //倾角roll : opt.roll   //旋转角            }});

附：相机参数获取

//将坐标转化为84坐标
get84Cood(positon) {let zb = Cesium.Cartographic.fromCartesian(positon);let lat = Cesium.Math.toDegrees(zb.latitude);let lon = Cesium.Math.toDegrees(zb.longitude);let height = zb.height;return {lon,lat,height};}
//获取相机参数
getCamera() {let p = this.get84Cood(viewer.camera.position);let position = [p.lon, p.lat, p.height];return {position,heading: viewer.camera.heading,pitch: viewer.camera.pitch,roll: viewer.camera.roll};}
