PURPOSE:To speed up parallel movement processing by minimizing access to a main memory when a 3D object, etc., is moved on a display screen in parallel. CONSTITUTION:An offset drawing instruction Ooj including offset values dx and dy of peak coordinates of the object OJ is interposed before a drawing instruction sequence Aoj for the object OJ and the object OJ is moved on the display screen in parallel with the offset values dx and dy. Data AD indicating addresses in the main memory 21 where a drawing instruction to be executed next is present are inserted into the header parts of the offset drawing instruction Ooj and the polygon drawing instructions IPa, IPb, IPc of the drawing instruction sequence Aoj. |
