  • An important class of splines are the so-called NURBS. NURBS is the abbreviation of Non Uniform Rational B-Splines. There are various introductional books on splines available. NURBS are very popular in games, design of cars, aeroplanes, fonts etc. Splines are also used in Isogeometric Analysis. The IGAA2018 conference was organised in Delft.
