Title:
METHOD AND DEVICE FOR GRAPHIC PROCESSING
Document Type and Number:
Japanese Patent JP3524143
Kind Code:
B2
Abstract:
PURPOSE: To provide the graphic processing method and device which can easily define the plane shapes of respective elements of a figure and generate the three-dimensional figure on the basis of those defined figure elements.
CONSTITUTION: This method is a graphic processing method which generates a three-dimensional figure on the basis of plural plane figures; and the plane figures are displayed and a closed area to be processed is indicated (S2 and S3) to define the plane shape of the indicated closed area (S6). Then the shapes of planes corresponding to the closed areas of other figures are defined, the widths of the closed areas and the shapes of the corresponding surfaces are compared, and the shapes of the planes corresponding to the closed areas are corrected. Those processes are performed for the respective planes of the figure and the three-dimensional figure is formed of the plane figures (S9).
