Abstract

We present a new technique for interpolation of scattered data on arbitrary surfaces. The interpolant is obtained as the restriction of a trivariate function and is piecewise defined over triangular surface patches. The smoothness of the resulting function over the domain surface is visualized by application of interrogation tools for surfaces on surfaces.
