Sun Position

Depending on the time of day and time, the sun is correctly positioned. The placement is crucial for the lighting of the scene and provides the user with a realistic image—keyword: Digital Twin.

For the times, it is considered whether the data is live or replay. In both cases, the current time of the selected airfield is used. Time, date, and location are relevant for the correct representation of the sun or the angle of the sun. Daylight Saving Time is taken into account when calculating the time, whether live or replay.

”Glider Viewer” also offers the display of flights at night. While this may not correspond to reality, it is a nice gimmick. Weather data and cloud representation follow the same rules as during the day. Only the placement of the moon does not correspond to reality.
