I want to know the exact world coordinates of a certain latitude and longitude. Is the coordinate of the (0, 0, 0) point after I change the longitude and latitude each time the world coordinate of the current longitude and latitude?

To convert any longitude/latitude/height to Unity world coordinates, first call `CesiumWgs84Ellipsoid.LongitudeLatitudeHeightToEarthCenteredEarthFixed` to transform the longitude/latitude/height to Earth-Centered, Earth-Fixed Cartesian coordinates. Then, feed those coordinates to the `TransformEarthCenteredEarthFixedPositionToUnity` method on your CesiumGeoreference object to get the corresponding Unity world coordinates.

If you just want to play an object at a particular longitude/latitude/height, consider adding the CesiumGlobeAnchor component to your game object instead.
