Verfahrung zum Generieren von Schatten in Videospielen

摘要

A game progress control means 61 administers positions of player characters and a referee character using positions corresponding to their waists. A shadow image generating means 62 generates shadow images of all the player characters and the referee character who appear on the screen of the monitor 2. A density setting means 63 sets the density of each shadow image based on the position of the appearing character on a soccer field using an x-coordinate of his waist. Accordingly, the shadow images of specified densities belonging to the individual appearing characters can be generated by simple calculation.
