Linear distance between two points of cesium
2022-07-06 19:57:00 【The most ferocious little seal】
Be careful : If you calculate the plane distance between two points , Let the height of two points be zero
The format of the point :
start_point = {
lon: ' longitude ',
lat: ' latitude ',
height: ' high ',
}
Code :
// Calculate the straight-line distance before two points according to longitude and latitude
function two_points_distance(start_point, end_point) {
// Longitude and latitude are converted into world coordinates
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);
// Returns the distance between two coordinates ( Company : rice )
return Cesium.Cartesian3.distance(start_position, end_position);
}
