<p><P>PROBLEM TO BE SOLVED: To provide a game device or the like, capable of improving image generation processing speed by simplifying expression of reflection objects using generated images. <P>SOLUTION: An object space composing part 220 composes an object space as a game space, and an inferior mirage polygon determination part 222 determines a polygon as an inferior mirage (inferior mirage polygon) in the object space. A rendering part 240 renders the object space from a viewpoint of a virtual camera to generate a background image. A texture generating part 242 specifies a reflection range of the inferior mirage based on a sight vector from the virtual camera and a normal vector of the inferior mirage polygon to generate a texture. The rendering part 240 also carries out mapping of the texture to the inferior mirage polygon, and combines a rendered image of the inferior mirage polygon with the background image. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
