<p><P>PROBLEM TO BE SOLVED: To provide a technique for easily simulating collisions and movement of objects arranged in a virtual space. <P>SOLUTION: A plurality of objects are arranged in the virtual space, and positions, speeds, and modes of the objects are stored in a storage part 401 of a simulation device 400, and a collision judgement part 402 judges whether or not objects being in a collision judgement modes collide with each other, and a collision updating part 403 calculates speeds after collisions of objects colliding with each other and updates the speeds of the objects with the calculation results and changes modes of the objects to a passage mode, and a movement updating part 404 calculates positions and speeds after an update interval time of the plurality of objects and updates the position and the speeds of the objects with calculation results, and a mode updating part 405 updates the passage mode of an object to the collision judgement mode when the object meets a mode return condition. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
