Abstract
A three-dimensional shape as a synthesis of three-dimensional geometry entities is controlled and displayed. The geometry entities are controlled in accordance with information defining the geometry entities, and layout information arranged in a three-dimensional space. An interface between graphic display apparatus using this graphic display method and an application system is practiced in that the transfer of the information on the geometry entities is carried out. The three-dimensional shape is divided into its geometry entities, and the display of an object having a three-dimensional shape is done as a synthesis of the geometry entities, the transfer of shape data being done separately for each geometry entity.
