IMAGE FORMING METHOD AND PROGRAM USED THEREFOR

摘要

PROBLEM TO BE SOLVED: To realistically express a rainfall state more than a conventional state. SOLUTION: This method forms an image by photographing a scene by a virtual camera 3 by constructing the rainfall scene in a virtual three- dimensional space 1 by a computer. A prescribed polygon 4 is arranged in the rainfall scene so as to move in the direction different from the rainfall direction over a plurality of frames. A semitransparent texture 5 for expressing, a plurality of waterdrops 5a is mapped on the polygon 4.
