| Abstract: | The algorithm of closed 2D point-sequence(PS) curve offset reconstruction is studied for rapid prototyping(RP) data processing.Characteristics of several existing algorithms for offset boundary reconstruction are analyzed.Based on the features of the closed PS curve offset in rapid prototyping data processing,a new algorithm for offset boundary reconstruction is proposed.Such an algorithm is based on the searching of valid intersection points.The algorithm has been compiled in a developed RP data processing software,and the stability of this RP data processing software is improved. |
