Android development: LocationManager's process of obtaining longitude and latitude and positioning (with demo)Location functions are often used in Android development, especially those that depend on the location function. Many people prefer Baidu map and AMAP sdks and open APIs, however, if you only need information such as longitude and
In a three-dimensional system, you must determine the sun position based on time and set this position as a specific light source.
To produce real lighting and shadow effects
The method for calculating the longitude and latitude of the direct sun point is as follows:
Based on the basic geographic knowledge,
Latitude: the lat

1, theoretical support: if from the point of need to judge a ray and the number of focus of the polygon is odd, then the point in this polygon, otherwise the point outside this polygon. (Rays cannot intersect with polygon vertices)
2, Programming Ideas:
The idea of the program is to make a horizontal ray (parallel to the x-axis, to the x-axis) from point A to the left to determine whether there is a focus on each side.
