Abstract:A novel scheme of mesh editing is proposed based on geometry signal spectrum analysis,which effectively combines mesh deformation in space domain and the geometry signal processing techniques in frequency domain.For intuitive interaction purpose,a geometry proxy of the original mesh is constructed,the consistent parameterization for both mesh and proxy are established.With signal spectrum analysis and conveying the deformation information from the geometry agent to the original mesh,we finally achieve the goal of mesh editing.The crucial innovation is the optimization of parameterizational mesh feature alignment scheme based on the radial basis function method.Additionally,an adaptive sampling approach is also devised for better sampling original model geometry signal.As extensions of spectrum editing scheme demonstrated in this paper,the editing principle is applied to mesh morphing and geometry details transferring with satisfying results.
