| Abstract: | According to the characteristics of RP technique ,a method of geometric modeling for complex surfaces is proposed. The method is capable of constructing the optimized STL file(the de facto file for RP machines )directly from digitized part data, so it radically avoids mistakes arisen from conversion by means of commercial CAD software systems. In addition to realizing the perfect match of grid number and reconstruction tolerance, the approach also improves the efficiency of RP pretreatment. Meanwhile, it provides a reliable way for the organic integration between reverse engineering and RP technology. |
