Abstract: An image generation system includes an object space setting section, a character control section, a virtual camera control section, an inter-camera distance setting section that sets an inter-camera distance based on at least one of position information, direction information, and moving state information about the character or the virtual camera, the inter-camera distance being a distance between a left-eye virtual camera and a right-eye virtual camera for generating a stereoscopic image, and an image generation section that generates a left-eye image and a right-eye image, the left-eye image being an image viewed from the left-eye virtual camera in an object space, and the right-eye image being an image viewed from the right-eye virtual camera in the object space.

Abstract: An image projected onto a screen from a projector is generated as follows. Specifically, two virtual viewpoints that correspond to the right eye and the left eye of a viewer are set in a virtual three-dimensional space, and two virtual planes are set to be circumscribed to the screen (plane of projection). A plane image is generated by perspective projection transformation of a game space onto the virtual plane based on each virtual viewpoint. A projection image is generated from each plane image according to the relationship between the pixel position of the virtual plane and the pixel position of the projection image that is defined so that the plane image is observed without distortion when observing the screen from a presumed viewing position to generate a right-eye projection image and a left-eye projection image.

Abstract: An image generation device includes a capture direction specifying section, a capture target specifying section, a marker placement control section that disposes a marker at the capture point, and an image generation section, the capture target specifying section determining whether or not the capture target is present in the capture direction, and specifying the capture target when the capture target is present, and the marker placement control section performing a depth value correction process that corrects the depth value of the capture point when a transition has occurred from a state in which the capture target is present to a state in which the capture target is not present.

Abstract: A program causing a computer to store a plurality of items of attribute information respectively associated with a plurality of part objects that form a model object in a storage section, and performing a hit effect process based on the attribute information of a part object among the plurality of part objects that corresponds to a hit position of the model object.

Abstract: Motion data of a model object is blended based on individual blend ratios ?A and ?B that are set for each bone of a skeleton. The individual blend ratios ?B for bones at end portions of the skeleton (weapons, hands, and feet) are high whereas those for main structural components (pelvis and chest) are low. A general blend ratio ? that is set uniformly for all the bones of the skeleton is also used. A plurality of motion control sections are made to operate simultaneously in parallel to select the motion data, based on motion scripts in which motion data to be selected and motion script switching conditions are defined, and the selected motion data is blended. A group of transitional motion scripts and a group of attack motion scripts are allocated to the first and second motion control sections, and transitional motions and attack motions are blended.

Abstract: The objective of the present invention is to provide a game machine and an information storage medium that make it possible to intensify the dramatic effect of a game by the voices sounded by a character. The pitch, volume, or tone of each voice sounded by characters (20) and (22) is varied in accordance with a physical strength parameter, the remaining play time, the progressing degree through game stages, or a number of wins. The pitch and volume of a voice sounded by a character increase as an opponent's physical strength parameter becomes larger, the remaining play time decreases, the final game stage approaches, or the opponent's number of wins becomes larger. The pitch, volume, or tone of voices is varied after the remaining play time has reached a given value or a given game stage has been passed. The increase in pitch of a voice sounded by a character is a whole tone or less.

Abstract: There is disclosed a three-dimensional game apparatus which enables a player to sense the passage of time and can give variety to game and demo scenes. The apparatus includes a virtual time computation section (120) for determining a virtual time by computing the passage of time in a virtual three-dimensional space from the actual passage of time in the real space; a virtual three-dimensional space computation section (100) for computing the positional information of an object and the positional information of a moving light source such as sun in the virtual three-dimensional space with the passage of the virtual time; and a three-dimensional computation section (210) for performing three-dimensional computations including a shading computation on the object disposed within the virtual three-dimensional space, based on the positional information of the light source.
