A baseball game is provided which imitates reality more closely by reflecting player data in game characters. Data relating to good hitting courses and bad hitting courses for each batter are incorporated as batter parameters, and the selection of a good or bad course by the batter can be reflected in the result of a hit, by varying the size of a collision object, or the like, in accordance with the batter parameters.

Game device, impact judgement method, and information storage medium

A computer graphic system wherein image element data can be processed efficiently at a high speed, and images of higher quality are produced at a lower cost than conventional. An image processor for dividing a screen into regions (fragments) of predetermined sizes and processing data on every divided region (fragment), wherein pieces of information on image constituting elements are rearranged in a direction vertical to a scanning line (ST1), the pieces of information on the image constituting elements are rearranged in a direction parallel to the scanning line (ST2), and image processing for opaque polygons, polygons with transparent pixels, and semitransparent polygons is performed in the order of mention on the basis of the rearranged pieces of information (ST3 to ST6).

Image processor and image processing method

Game device, collision determination method and information storing medium

According to the image processing method, when the number of shadow polygons existing between a depth position of pixels of ordinary polygons subject to shadowing and an infinite position is counted and that number is an odd number, those pixels are unconditionally judged to be positioned inside a region of shadow volume. Therefore, regions to undergo shadowing can be efficiently detected by judging whether the number is an odd number or an even number at all pixel positions.

Image processing device and image processing method

Disclosed are an image processing apparatus and an image processing method, which can efficiently execute a hidden-surface process, a blending process on translucent polygons and a shading process by a light source all in a rendering process. An image processing method for generating image data for displaying a plurality of polygons comprises: a mask generation step of receiving polygon data including position data of the polygons in the display screen, generating first mask data indicating effective pixel areas of the polygons in a display screen and Z values indicating depths in the display screen for respective effective pixels from the polygon data, generating second mask data having, as an effective pixel area, a pixel area having a Z value in the foreground of a Z value of another processed polygon among the effective pixel areas of the first mask data, executing an exclusion operation to delete the effective pixel area of the generated second mask data from the effective pixel area of generated second mask data of another polygon to thereby generate trans mask data, and performing generation of the trans mask data polygon by polygon; and a rendering step of implementing a rendering process on each of the polygons with respect to the effective pixel area, indicated by trans mask data generated in the mask generation step.
