Abstract: Subdivision wavelets have been developed very fast in recent years. They are widely used in computer graphics, progressive transmission and multiresolution editing etc. Based on the lifting scheme, Bertram has introduced a bi-orthogonal wavelet construction for the Loop subdivision. The vertexes involved in the Bertram’s method are all inner ones in the subdivision surface. The paper presents a method to deal with the boundary of the mesh with subdivision wavelets. Tests show the feasibility of the approach.

Key words: computer application, loop subdivision surface, subdivision wavelets, surface boundary subdivision
