Patent ID: 7881521

Claim:
An image generation method for generating an image, the method comprising: storing object data in an object data storage section; disposing a plurality of objects in an object space, based on the object data stored in the object data storage section; controlling a virtual camera; generating an image viewed from the virtual camera in the object space while performing hidden surface removal processing; disposing in the object space, a model object including a plurality of part objects each of which has a projection shape, a three-dimensional projecting portion and a display surface on which an image is drawn, the projecting portion extending at least in a direction perpendicular to the display surface, wherein a central part object included in the model object stands along a vertical central axis, and the rest of the part objects are positioned apart from the central axis of the central part object, the central axis extending through a center of the central part object; and rotating each of the part objects orbitally about the central axis, with a processor, based on rotational information of the virtual camera so that the display surface of each of the part objects is directed toward the virtual camera when the virtual camera orbitally rotates about the central axis while being directed toward the central part object.
