IPC: A63F13/55
Filed: 2001-05-01
Abstract: PROBLEM TO BE SOLVED: To provide a game system capable of efficiently generating an image having a higher quality contour and to provide a program and an information storage medium. SOLUTION: The image of the contour EDL of an object OB is changed in accordance with the distance from a viewpoint and the size of the object OB after perspective transformation. The farther the distance from the viewpoint or the smaller the size of the object after the perspective transformation, the closer the color of the contour of the object gets to the second color. The color of the contour starts to approach the second color at a threshold VTN and is set to the second color at a threshold VTF. The farther the distance is from the viewpoint or the smaller the size of the object after the perspective transformation is, the more transparent the image of the contour of the object is.  When the distance (the size of the object) from the viewpoint is in the vicinity of a distance in the following movement mode of the viewpoint, the color and semitransparency of the contour are kept almost constant. When the distance from the viewpoint is the threshold VTF, the image of the contour is almost invisible. The image of the contour is plotted in the outer area and the inner area of the object.
