<p><P>PROBLEM TO BE SOLVED: To provide a video game machine where a throughput is reduced by avoiding complicated processing such as judgment of intersection of the lines of sights. <P>SOLUTION: The video game machine 10 is provided with: an IO 20 to which operation information of a game machine is input; a CPU 50 which moves a vehicle (mobile object) based on the operation information on a course in a virtual three-dimensional space in which a plurality of polygons are arranged, which makes a camera (virtual view) follow the vehicle and which outputs the video of the vehicle seen from the camera as video information; a display device 70 for displaying the video based on the video information; a memory 40 stored with phase coordinates showing prescribed positions on the course; a hit judgment part 51 for judging the position of the vehicle; a position coordinate working part 52 for transforming the judged position of the vehicle to a position on the phase coordinate and setting the position of the camera on the phase coordinate from the position of the vehicle; a coordinate transformation part 53 for transforming the position of the camera to a position in the virtual three-dimensional space; and a view position calculation part 54 for calculating the position of the actual camera in the virtual three-dimensional space. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
