ABSTRACT
Interactive technique for shape manipulation is highly desirable in geometric modeling community. In general, designers are often required to manipulate the shape of large, complex or specific 3D models with no smooth features. In this study, we assume that the large, complex or special 3D models can be defined and characterized by a rather small set of feature lines. The goal of shape manipulation is achieved by deforming the important geometric features interactively. To this end, we first pre-analyzed the 3D large, complex or specific shapes to get the feature lines. The feature lines are defined as the ridge-valley lines of 3D models. Next, the interactive operations for manipulating the feature lines are proposed. We design a brush operation to manipulate the local regions of focus vertex. The new positions and normals of the vertices in the local region are approximated. The new model is finally reconstructed according to compactly supported basis function with the vertices and their normals after manipulation. Experimental results show that our method enable designers to control the shape of 3D models effectively.
