AI-generated Key Takeaways

• GMSVisibleRegion defines the geographical area visible within a map's camera view, represented by a polygon with four corners.

• This polygon can be a trapezoid or a rectangle depending on the camera's tilt, with a trapezoid shape occurring when the camera is tilted.

• The GMSVisibleRegion struct includes properties for the coordinates of the four corners: nearLeft, nearRight, farLeft, and farRight.

• These corner coordinates represent the bottom left, bottom right, far left, and far right corners of the visible camera view respectively.

GMSVisibleRegion

struct {}

GMSVisibleRegion contains the four points defining the polygon that is visible in a map’s camera.

This polygon can be a trapezoid instead of a rectangle, because a camera can have tilt. If the camera is directly over the center of the camera, the shape is rectangular, but if the camera is tilted, the shape will appear to be a trapezoid whose smallest side is closest to the point of view.

• nearLeft

  Bottom left corner of the camera.
