Abstract: A lighting model storage unit (205) stores therein a lightning model in which a light source is provided to a model body. A parts selection unit (203) reads an outline shape stored in an outline information storage unit (201) and selects a combination of parts to be arranged to the outline shape from the parts images stored in the parts storage unit (202). A map storage unit (204) stores therein a map where the selected parts are arranged to the outline shape. A lightning model applying unit (206) applies a lightning model matching the map. An image drawing section (207) draws a three-dimensional image on the map where the parts are arranged by combining the cooler components from the light source according to the applied lighting model.

Abstract: First, positions at opposite widthwise sides where a trace is to be created are calculated. Then, the calculated positions are successively determined as vertices to generate a polygon for the trace. Subsequently, a texture suitable for the type of the slope with which a snowboard is in contact is selected. Whether or not the selected texture has been changed is then discriminated. If the selected texture has been changed, a transparent processing is applied to textures before and/or after a change and these textures are adhered to polygons before and/or after the change. Accordingly, a three-dimensional image processing apparatus can realistically and easily create a trace formed on a ground surface or a water surface as a character runs or slides.

Abstract: A character in a video game space is represented realistically and the demo screen is made enjoyable for a user. A start demo display processing unit 100 comprises a motion order assigning unit 101 which refers to any of a plurality of motion probability setting tables 111 based on the player selection in the player setting unit 122 and randomly assigns, based on the probability, the order of arrangement for the motions, a motion reproduction assigning unit 102 for assigning the reproduction of motion in this order to the image processing unit 11, and a motion interpolation assigning unit 103 for assigning to the image processing unit 11 the interpolation to the next motion close to completion of a motion.

Abstract: A video game is played on a video game system by moving objects successively introduced into a game field in one direction on a display screen, determining whether a leading object or a leading cluster of objects introduced into the game field reach a predetermined position in the display screen or a memory, and ending the video game if the leading object or the leading cluster of objects introduced into the game field reaches the predetermined position. It is determined whether objects of one type are successively connected in the game field or not. The objects of one type are removed from the game field if they are successively connected in the game field. An object present ahead of the removed objects in the direction is moved in a direction opposite to the direction. An object indicated by a cursor is exchanged for an object present in the game field.
