Abstract. In this paper we introduce an unified framework for topological manipulation on triangulated 2manifolds with or without boundary. We show that there are two kinds of prim...
Abstract. Nonnegative bivariate interpolants to scattered data are constructed using some C1 macro-element spline spaces. The methods are local, and rely on adjusting gradients at ...
This paper derives strong relations that boundary curves of a smooth complex of patches have to obey when the patches are computed by local averaging. These relations restrict the...
