Abstract:
A shape generating or shape displaying method comprising:a step of setting a basic shape forming set, that is a fundamental unit structure, which accomplishes a systematic organization so as to unitarily carry out a generating or displaying process of a target shape, and developing a data of the basic shape forming set in a memory, and then supplying them to an arithmetic unit; a step of setting an upper side management or control structure which is for sequentially constructing a super-structure of a hierarchical structure by way of recursively repeating a substructure from a basic shape forming set of assembling information to a higher rank of hierarchy, systematically linking data of said upper side management or control structure to data of said basic shape forming set and developing as a group of a 1st table in the memory, and then supplying them to said arithmetic unit; a step of setting an under side management or control structure which is for sequentially constructing a last-structure of a hierarchical structure by way of recursively repeating a substructure from a basic shape forming set of geometric information to a lower rank of hierarchy, systematically linking data of said under side management or control structure to data of said basic shape forming set, and developing as a group of a 2nd table in the memory, and then supplying them to said arithmetic unit; and a step of carrying out a dynamic management or control by way of using the arithmetic unit based on acquiring data of upper and lower management or control structures, which determines a structural relationship and is located in said basic shape forming set, from said groups of said 1st table and said 2nd table as connecting information that has a systematically linked unitary hierarchical structure; thus performing a unitary shape processing.
