| Abstract: | In order to support concurrent design and manufacturing, the research focuseses on sculptured surface interrogation method for visibility direction information. A method of extracting and analyzing visibility direction of sculptured surface geometry is presented, and an algorithm of computing visibility direction is developed. Using the algorithm, a visibility direction set is acquired for the given surface patch. By the method, manufacture information can be acquired effectively in the design stage, manufacturability of the design can be analyzed. |
