This is a real-time interactive solar illumination simulation system, which can be used for simulating the sunlight conditions of urban buildings and so on. It has the following functions:

1. The height and position of the sun follow the movement trajectory in the real world, that is, they are related to the current date, time and the latitude of the earth where the observer is located.

2. The current date and time can be customized or you can choose the system time of the computer.

3. The display time can have its speed adjusted, that is, the sun can complete the trajectory display of a day within a very short period of time.

4. The display time can be paused or reversed.

5. The latitude where the observer is located can be customized, or you can choose some of the built-in major cities, and the approximate latitude positions on the world map will be simultaneously displayed below.

6. The current orientation can be displayed in real time at the top of the screen, which is the function of a compass.

7. The illumination intensity and color temperature of the sunlight also change with the height.

8. The icon style can be changed to the one you need in the widget blueprint.
