Local Smoothing

Splitting a surface into a set of patches can result in relatively acute angles at vertices of some of the patches and consequently leads to poorly shaped triangles sharing these vertices. Apparently, shape of these elements cannot be improved by global smoothing. Therefore a local smoothing should be performed where it is necessary. The local smoothing is based on the same principle as the global one but operates only on the internal interfaces of individual patches (taking into account both patches sharing this interface) and their immediate vicinity. It is obvious from the nature of the local smoothing that it can be processed only in the physical space.
