Abstract: | The registration of 3D form features is essential to the supporting of reverse shape design processes. Extracting an editable shape feature from unordered data points is notoriously hard. We present a new method to extract a shape instance plus design parameters from a ridge structure contained in a freeform surface, where the ridge has no predefined path, and can have varying height and width as a function of cumulative arc-length. This complex feature is uncovered by a match-and-crawl algorithm based on partial template matching and shape dissimilarity computation. The (varying) longitudinal direction of the ridge is explicitly registered as a function of arc-length, as are its width and height. The latter two quantities are yielded as independent parameters for subsequent interactive shape modeling processes. |
