<p>PROBLEM TO BE SOLVED: To generate a real image reflected with the position, size and direction of impulse with a little data amount and arithmetic load by operating the position, vector size and direction of impulse applied to an object and generating the image of a rotating object on the basis of these data. SOLUTION: When a bullet hits a door 720 as rotating object, the position, vector size and direction of impulse caused by the bullet are found. A component VD in the tangential direction of an impulse vector in respect to the rotation orbit of the door 720 is found. A force T for rotating the door 720 is found on the basis of a ratio between a reference length in a radial direction and a distance from a rotation center to the impulse position and the VD. An angular rotation acceleration (a) is found from the T and the resistance of air or the like and an angular rotation velocity V of this time is found from (a) and the angular rotation velocity of the last time. The rotation angle of this time is found from V and the rotation angle of the last time. On the basis of the found rotation angle, the door 720 is arranged and an image including the door 720 is generated.</p> |
