一、经纬度转换为世界坐标
1.Cesium.Cartesian3.fromDegrees(longitude, latitude, height, ellipsoid, result)
2.var ellipsoid=viewer.scene.globe.ellipsoid;
var cartographic=Cesium.Cartographic.fromDegrees(lng,lat,alt);
var cartesian3=ellipsoid.cartographicToCartesian(cartographic);
二、 世界坐标转换为经纬度
1.var ellipsoid=viewer.scene.globe.ellipsoid;
var cartesian3=new Cesium.cartesian3(x,y,z);
var cartographic=ellipsoid.cartesianToCartographic(cartesian3);
var lat=Cesium.Math.toDegrees(cartograhphic.latitude);
var lng=Cesium.Math.toDegrees(cartograhpinc.longitude);
var alt=cartographic.height;
2.Cartographic.fromCartesian
三、屏幕坐标和世界坐标相互转换
1.var pick1= new Cesium.Cartesian2(0,0);
var cartesian = viewer.scene.globe.pick(viewer.camera.getPickRay(pick1),viewer.scene);
2.Cesium.SceneTransforms.wgs84ToWindowCoordinates(scene, Cartesian3);
