We present a new interpolatory subdivision scheme based on PB-splines (Point-Based B-splines), over triangular meshes. Using the stencil of the interpolatory √ 3subdivision scheme, we propose a different refinement strategy by introducing a variable α to each regular vertex (valence = 6). By applying different α (locally or globally), the scheme is suitable for adaptive refinement and can perfectly reach different smoothness conditions (C 0 , C 1 or C 2 ).
