| Research Abstract |
As the fundamental techniques in the reverse engineering, we developed the segmentation techniques such as the one with platonic solids, and the one identifying the analytic surfaces for example, conics and spheres, and thus segmenting the remaining free-form surfaces, based on the feature lines. We concluded that the line-based method is the best among them. We also enhanced the combination algorithm of T-splines. Moreover we developed the technique to accelerate the segmentation algorithm.
