ABSTRACT:
A method and apparatus for retrieving graphical data from a graphic data processing system that processes graphical forms, the graphic data processing system being responsive to a processing request to retrieve a graphical form from a designated region or a processing request to display a graphical form from a designated region. A three-dimensional figure is established which contains at least one graphical form and a spatial position of the three-dimensional figure is obtained. The spatial position is stored as region information. Graphic data for each graphical form contained in the three-dimensional figure is stored as graphical information. A graphic element is formed for the three-dimensional figure, the graphic element being a combination of the region information for the three-dimensional figure and the graphical information of each graphical form contained in the three-dimensional figure. When a processing request is requested for a designated region, it is determined whether the three-dimensional figure lies at least partially within the designated region, the determination being performed by analyzing the region information of the graphic element. The graphic data contained in the three-dimensional figure is excluded from further processing by the processing request when the three-dimensional figure is determined to lie outside the designated region. The graphic data contained in the three-dimensional figure is selected for further processing by the processing request when the three-dimensional figure is determined to lie within the designated region.
