I make a map of the city. The map is controlled by gestures, multi-touch (zoom and move) When you select a point on the map to the right should appear enlarged portion of the card, with the ability to change the proportions of the main card and increased. The map will also be separate layers.
Implemented using two cameras and change camer rect. When you change the camera that reside at a distance loses clarity. Rect problems without having to change is not observed.
