摘要: There does not usually exist a closed general NURBs representation of the offset curve (or surface) to (surface). In related paper [6] method was developed determine sequence approximations (surface) given with properties that global error each approximation from true can be bounded and converges offset. this we take next step develop using analysis function perturbs control points specified an (surface), so better results.
