We propose a method which generates high-quality sharp features on triangular mesh surfaces. Triangular meshes, which are interpolated as subdivision surfaces, have been used to express compound surfaces, because they automatically satisfy continuity among arbitrary meshes. But the quality of sharp features such as creases or corners at an arbitrary part of a mesh is not investigated enough. Hence, we introduce triangular spline with C0 continuity by inserting extended meshes at specified edges to explicitly control the shape of sharp features and to represent them with triangular Bézier patches. Then we apply this technique to control tangential planes along the specified edges.
