1、cesium坐标——笛卡尔转经纬度
const cartesian = {
x: -2385475.526887967,
y: 5390811.453960502,
z: 2426849.2019715696
}
const cartographic = Cesium.Cartographic.fromCartesian(cartesian)
const longitudeString = Cesium.Math.toDegrees(cartographic.longitude)
const latitudeString = Cesium.Math.toDegrees(cartographic.latitude)
const heightString = cartographic.height
console.log(longitudeString, latitudeString, heightString)
2、经纬度转笛卡尔
var origin = Cesium.Cartesian3.fromDegrees(113.86975855, 22.51165379, 0)
