The resulting subdivision surfaces achieve C1 continuity with the convex hull property. This scheme can be regarded as either a four-directional subdivision or a special quadrilateral subdivision. When used as a quadrilateral subdivision, the proposed scheme can control the shape of the limit surface more flexibly than traditional schemes due to the natural introduction of auxiliary face control vertices.CCS Concepts: Computing methodologies -> Shape modelingComputing methodologiesShape modeling10.1111/cgf.1493312 pages
