<p><P>PROBLEM TO BE SOLVED: To provide a program or the like realistically expressing a silhouette color. <P>SOLUTION: This image generation system includes: a vertex shader part performing processing in vertex units; and a pixel shader part performing processing in pixel units. The vertex shader part outputs a vertex normal vector of an object. The pixel shader part finds a color control parameter on the basis of a view line vector and a normal vector of each the pixel obtained by the vertex normal vector outputted from the vertex shader part. The silhouette color of the object having a color darker near an outline of the object, and lighter away from the outline of the object is found on the basis of the found color control parameter, and the found silhouette color and the color of the object are combined. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
