A game machine is provided in which processing load for displaying a scene of falling snow or falling rain, for example, on a game screen in a three-dimensional game can be reduced. An environmental effect object placement unit (snow object placement unit (64)) places a plurality of environmental effect objects in a target region of a three-dimensional game space based on a viewpoint position and a sight line direction. A target region controlling unit (snow generation target region controlling unit (60)) moves the target region, in response to a change of the viewpoint position or the sight line direction, based on the viewpoint position and sight line direction after the change. A display unit (70) displays a game screen representing a scene, in the three-dimensional game space in which the plurality of environmental effect objects are placed in the target region, viewed from the viewpoint position toward the sight line direction. |
