摘要：

Many applications require that smooth convex surfaces be approximated by polygonal functions. While there exist methods for determining optimal tangent points for definition of exterior facetings of such surfaces, they are not practical to compute for many real-world problems. Asymptotically optimal tangent points are nearly as useful, and using the result presented here, are far more easily computed. (C) 1997 Elsevier Science B.V.
