PICTURE GENERATION DEVICE AND INFORMATION STORAGE MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a picture generation device and an information storage medium capable of reflecting the flow of a fluid in a course to the behavior of a traveling body. SOLUTION: Based on operation data and flow data set on a course 20 within an object space, the traveling body 22 is moved on a course 20. A flowing speed VSn is made maximum on a course cross section and flowing speed VLn or VRn at the left and Ln or the right end Rn of the course is made lower than this VSn. Then, the flowing speed VLn or VSn at the left end Ln or the right end Rn of these courses is made to be higher than 0 so as to be different from a flowing speed in an actual world.
