Method of creating a dynamic image, storage medium and program executing apparatus

摘要

A three-dimensional CG image is created with a small processing volume. As shown in Figs. 5A through 5G, positions in a three-dimensional space associated with sparks of a firework are calculated in accordance with motion characteristics of the sparks (Figs. 5A, 5B and 5C). Positions on a camera screen are obtained which are positions where calculated positions of the sparks at the current point in time in Fig. 5C are projected, and a spark texture D is drawn in those positions to represent a firework as shown in Fig. 5F. <IMAGE>
