Movie texture mapping is performed in which compressed textures CTEX-1 to CTEX-N are expanded to form expanded texture ETEX-1 to ETEX-N which are in turn mapped onto an object in a sequential manner. Movie texture mapping for the random replay is performed in which textures are mapped on the object OB1 in the order starting from ETEX-K, and also on the object OB2 in the order starting from ETEX-L. Movie texture mapping for the frame-decimation replay is performed in which mapping of the expanded texture ETEX-I is followed by mapping of the expanded texture ETEX (I+J) (when J>=2). The compressed movie texture data contains data used to designate storage locations of the compressed textures CTEX-1 to CTEX-N . The objects OB1 and OB2 can be arranged to overlap each other to represent an image having an increased area such as a flame image. Replay starting frames K and L may be randomly set, and the number of texture frames to be decimated (J-1) may be determined according to event occurrence or time passage.
