    • First determination means determines at a unit time interval whether or not a magnitude of a change amount vector is equal to or larger than a first threshold value. When it is determined that the magnitude of the change amount vector is equal to or larger than the first threshold value, predetermined processing is executed. Also, when it is determined that the magnitude of the change amount vector is equal to or larger than the first threshold value, a swinging direction in which an input device is swung is calculated, and whether or not the change amount vector which shifts in a direction opposite to the swinging direction intersects with a second threshold value is determined by second determination means. After it is determined that the change amount vector intersects with the second threshold value, further, whether or not the magnitude of the change amount vector is smaller than a third threshold value is determined by third determination means. When the first determination means determines that the magnitude of the change amount vector is equal to or larger than the first threshold value, the first determination means waits for a determination that the magnitude of the change amount vector is smaller than the third threshold value to be made, and restarts the determination as to whether or not the magnitude of the change amount vector is equal to or larger than the first threshold value.
    • 第一确定装置以单位时间间隔确定变化量矢量的大小是否等于或大于第一阈值。 当确定变化量向量的大小等于或大于第一阈值时,执行预定处理。 此外,当确定变化量向量的大小等于或大于第一阈值时,计算输入装置摆动的摆动方向,以及是否改变输入装置摆动的变化量向量 由第二确定装置确定与摆动方向相反的方向与第二阈值相交。 在确定变化量矢量与第二阈值相交后,进一步由第三确定装置确定变化量矢量的大小是否小于第三阈值。 当第一确定装置确定变化量向量的大小等于或大于第一阈值时,第一确定装置等待确定变化量向量的大小小于第三阈值 并且重新开始关于变化量向量的大小是否等于或大于第一阈值的确定。

    • An image generation method includes: generating a two-dimensional image by perspectively transforming a virtual three-dimensional space relative to a predetermined viewpoint at a given instant; determining a corresponding position to a representative point of a waterdrop on the two-dimensional image depending on a position at which the waterdrop exists in the virtual three-dimensional space or a position at which the waterdrop is to be displayed in a display image; determining a reference position on the two-dimensional image corresponding to a vertex or a configuration point which forms the waterdrop, by using reference information relative to the corresponding position to the representative point on the two-dimensional image, the reference information being previously determined for the vertex or the configuration point forming the waterdrop; and linking the determined reference position with the vertex or the configuration point forming the waterdrop and mapping at least a portion of the two-dimensional image onto the waterdrop to generate an image of the waterdrop at a given instant or in a frame proximate to the instant.

    • An image generation system, program, and information storage medium can realistically represent reflection of light on a given object or topographic surface with a reduced computation load. The image generation system includes a section which assigns, to a given object or topographic surface disposed in a virtual three-dimensional space, a virtual object which has at least one of nonuniform brightness or color and is used for representing a light reflection effect on the object or topographic surface; a section which determines a position of the virtual object so that the virtual object moves to follow a virtual camera or player's character, and disposes the virtual object at the determined position; and a section which generates an image of the virtual three-dimensional space viewed from the virtual camera by performing translucent blending processing of the object or topographic surface and the virtual object assigned to the object or topographic surface.
