The patent further makes an important note about polygon edges that lie along the display border. It is undesirable to have the path use the display border unnecessarily as this might trigger the game into loading an adjoining game scene.In order to prevent the shortest path algorithm from using polygon edges that lie along the display border, the distance for such edges is defined to be infinity. | The patent further makes an important note about polygon edges that lie along the display border.
