Corrigendum to G 2 B-spline interpolation to a closed mesh [Comput Aided Des 43 (2011) 145-160]

A G 2 interpolation method to a closed mesh was proposed by Shi et?al. in [1]. This note points out that their method has two theoretical defects, which may lead to the failure of G 2 continuity. We fix these defects and correct several formula mistakes.
