Abstract—In computer graphics, some regions on a 3D model are often required to precisely preserve the features during editing. This paper proposes a new feature preserving mesh editing method. First we use one of the existing mesh editing methods to estimate the final editing result. Then we get the deformation function between this result and the input mesh. Using singular value decomposition on the deformation function of each faces in the feature region which specified by user, we extract the rigid component of the function. Our method keeps the global shape of the feature region, and avoids the scale and distortion that cause the visual unpleasing. We also propose a refined algorithm which makes the resulting mesh more reasonable. The framework produces visually pleasing editing results with simple user interaction.

Index Terms—Mesh editing, differential coordinates, singular value decomposition, feature preserving.
