GoogleNavigation Framework Reference

  • GMSVisibleRegion defines the four points of a polygon that represents the visible area on a map.

  • This visible area can be a trapezoid or a rectangle depending on the camera's tilt: rectangular when looking directly down, trapezoidal when tilted.

  • When tilted, the trapezoid's smallest side is the closest to the viewer's perspective.

GMSVisibleRegion

typedef struct GMSVisibleRegion GMSVisibleRegion

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.
