<p><P>PROBLEM TO BE SOLVED: To reduce usage quantity of a memory by using only the data constituting one side of a symmetric shape. <P>SOLUTION: When the shape of a character as a display object is symmetric with respect to a predetermined reference plane, a predetermined program is read, a matrix for vector computation is acquired, and only the model data constituting one side to the predetermined reference plane are acquired. When an apex of the model data is detected and that on the other side of the objective position on the predetermined reference plane is detected, mapping of the apexes is carried out via a mirror image relationship with respect to the reference plane, and consequently, memory usage for image processing can be reduced. <P>COPYRIGHT: (C)2003,JPO</p> |
