Abstract

This article examines approximation issues in applied geometry. Calculations in such problems are based on the 3D approximation of curves and surfaces. Surface approximation can be narrowed down to a function of one variable. A type of multifunction interpolation (see article I in the journal) is proposed. Errors are estimated and circular arc interpolation convergence is proven. A brief description of practical application of the method is given.
