IMAGE PRODUCING METHOD, STORAGE MEDIUM AND PROGRAM EXECUTION DEVICE

摘要

PROBLEM TO BE SOLVED: To produce a three-dimensional CG image with a small throughput. SOLUTION: The positions of points corresponding to the sparks of a firework are successively calculated in a three-dimensional space in accordance with the induction characteristics of the sparks (A, B, C). A position where the position C of a calculated current point is projected on a camera screen is calculated, and the textures D of sparks are drawn at the calculated position on the camera screen to show a firework F.
