Abstract: An animation control unit specifies shape data, hierarchical structure data, a group table, and state information. A character state calculating unit obtains the specified shape data from a shape data storing unit, the hierarchical structure data from a hierarchical structure storing unit, and the group table from a table storing unit. The character state calculating unit also obtains motion data shown in the specified state information from a motion data storing unit and specifies, from the obtained motion data, motion data identified by each group number. In accordance with the obtained hierarchical structure data, the character state calculating unit corrects the shape data by using the specified motion data. A three-dimensional rendering unit renders the corrected shape data to generate an image, and a display unit displays the generated image.

In this manner, realized is the rendering device Urend1 capable of generating the display image data having no deformation on lines when displayed.
