Abstract: Most hole filling approaches use techniques to fill up a hole first and then to smooth it. Very few tries rebuild features on the filled surface of the original 3D model. We propose an efficient hole-filling methodology which preserves sharp features of the geometry of the original model. The main idea is that we reconstruct feature curves in the missing parts of the given mesh before filling the hole with smoothing surface. The feature curves in the missing part are reconstructed by extending salient features of the existing parts. The hole is partitioned into several smaller and more planar sub-holes divided by the feature curves and then the hole-filling step follows. User intervention is available to design the features to be desired shape to guide feature curve reconstruction wherever ambiguity exists or results are unsatisfactory. Our hole filling techniques is different from other existing techniques as features are taken as the first subject to reconstruct, which eventually drive the feature-definite surface filling process. It is also very efficient as a user is interfering only with features and the actual hole-filling step is dealing with only planar holes. (More)
