Autor: LEAL NARVÁEZ, NALLIG EDUARDO, LEAL NARVÁEZ, ESMEIDE ALBERTO, BRANCH, JOHN WILLIAN

Publikováno v: DYNA, Volume: 78, Issue: 166, Pages: 133-141, Published: APR 2011

Modeling with Non Uniform Rational B-Splines (NURBS) surfaces has become a standard in CAD/CAM systems due to its stability, flexibility, and local modification properties. The advantage of fitting with NURBS surfaces is well known, but it is also kn
