场景基础 ​

//1.初始化事件句柄
var handler = new LSGlobe.ScreenSpaceEventHandler(viewer.scene.canvas);

//2.添加事件句柄鼠标操作类型
handler.setInputAction(function (movement){
    //movement.position当前的屏幕坐标
}, LSGlobe.ScreenSpaceEventType.LEFT_CLICK);
//LEFT_DOWN左键按下时触发
//LEFT_UP 左键弹起时触发
//LEFT_CLICK 左击时触发
//RIGHT_CLICK 右击时触发
//DOUBLE_CLICK 双击时触发
//MOUSE_MOVE 鼠标移动时触发

//3.事件销毁
Handler.destroy();

//屏幕坐标转世界坐标
var Pos=scene.pickGlobe(movement.position);
//movement.position 鼠标事件触发时返回的坐标

//世界坐标转屏幕坐标
var movement = LSGlobe.SceneTransforms.wgs84ToWindowCoordinates(scene, pos);
//scene 场景对象 pos世界坐标

//世界坐标转换为经纬度
var cartographic = LSGlobe.Cartographic.fromCartesian(Pos);
//Pos世界坐标对象

//经度
var currentClickLon = LSGlobe.Math.toDegrees(cartographic.longitude);
//纬度
var currentClickLat = LSGlobe.Math.toDegrees(cartographic.latitude);
//高度
var height= cartographic.height;

//经纬度换为世界坐标转
var ellipsoid=viewer.scene.globe.ellipsoid;
var cartographic=LSGlobe.Cartographic.fromDegrees(longitude,latitude,height);
//longitude经度 latitude维度 height高度
var cartesian3=ellipsoid.cartographicToCartesian(cartographic);

//经纬度转弧度
LSGlobe.Math.toRadians(degrees)

//弧度转经纬度
LSGlobe.Math.toDegrees (radians)
