Patent US 8,836,699

By applying computer aided method, different combinations of 3D objects derived out of a set of pictorial characters may be generated in a computer system. Some of the 3D objects may be used as sources of landmark designs. Users can simply refine these objects with ‘function’, ‘program’ and ‘budget’ to further achieve their specific design goal. By screening a limited number of computer-generated 3D objects based on a selected candidate character set and operation rules, the system enables a designer to focus on selected potential objects as an initial design step, rather than starting everything from the scratch as in a conventional process.
