Smog Central

video explanation

The girl is moving around a black fan on top of the map. The fan is responsible for moving smog. The UI on the phone tells what country is being aimed from and to at any given moment. The fan is controlled by a tracked image. This image was put on a 3D printed pillar. By having a pillar it gets easier to get a grip while holding the image in an interactive manner. A ray goes from the camera to the world position of the fan. That way, the ray collides with countries on the map. Upon colliding, the country aimed at gets selected as the current country for the fan to stand on in the game.
