Cesium 两点之间的直线距离
2022-07-06 11:51:00 【最凶残的小海豹】
注意:如果计算两点的平面距离,让两个点的高为零即可
点的格式:
start_point = {
lon: '经度',
lat: '纬度',
height: '高',
}
代码:
// 根据经纬度计算两点之前的直线距离
function two_points_distance(start_point, end_point) {
// 经纬度转换为世界坐标
var start_position = Cesium.Cartesian3.fromDegrees(start_point.lon, start_point.lat, start_point.height);
var end_position = Cesium.Cartesian3.fromDegrees(end_point.lon, end_point.lat, end_point.height);
// 返回两个坐标的距离(单位:米)
return Cesium.Cartesian3.distance(start_position, end_position);
}
