IMAGE FORMING METHOD, STORAGE MEDIUM AND PROGRAM EXECUTION DEVICE
Document Type and Number:
Japanese Patent JP3286633
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain an image expressing the movement of an object 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). Then, 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. The segments which connect together the points (points set on the same radial line) configuring the history of points on the camera screen where the points corresponding to the sparks are projected are drawn about each spark. Thus, an image G showing the loci of sparks is obtained.
