PURPOSE:To improve the efficiency of pattern processing by programming the pattern processing in which phase structure changes dynamically and successively by considering list-structure capable of dealing with dynamic change flexibly to be basic data. CONSTITUTION:An object expressing means 1 express a three-dimensional object by an all apexes list, an all edge lines list and an all faces list. An apex expressing means 2 expresses an apex by an apex coordinates, an edge line list and a face list. An edge line expressing means 3 expresses an edge line by two apexes. A face expressing means 4 expresses a face by an apex list. In order to make the development of a program easier, the boundary expressing system of the three-dimensional object whose basic data is the list system is adopted. The data of the object is represented concretely by using processing language as program language. Besides, since data control for the change of originally dynamic data is included in a system side, even in such application that the addition or the deletion of the pattern occurs frequently, the program becomes simple. |
