<p>A node gathering unit (11) has a polygon group and a texture image group as inputs, and determines nodes corresponding to a texture image group to bind. Said polygon group has a relationship represented by multiple detail levels in a tree structure, and expresses a model by means of the multiple detail levels. Each member of said texture image group is allocated uniquely to the polygon group. A texture atlas generation unit (12): uses node information generated by the node gathering unit (11) to bind the texture image group and generate a texture atlas group; and transforms texture coordinates of the vertices of the polygon group, said texture coordinates being transformed in correspondence to drawing positions.</p> |
