Abstract: This paper introduces a novel Loop subdivision method, which produces a C1 continuity surface including boundaries and creases. The new rules develop Loop subdivision surface by adding a parameter known as a knot interval. Sederberg et al. used knot intervals for sharp features in subdivision surface modeling for the first time. This paper extends the subdivision rule to triangular subdivision meshes. It can generate a pleasant result in Loop subdivision surfaces.
