Triangular mesh fitted to NURBS surface

{{$t('general.by')}}

This is a problem that a number of AAC students address each year: attempting to fit a regular mesh to a NURBS surface. This code gives the basics of moving points on a mesh covering a NURBS surface by changing their u,v coordinates as a starter. For more involved solutions, see for example <a href="http://www.aac.bartlett.ucl.ac.uk/reports/tsigkari.html";>Martha Tsigkari, 2006, Tessellation of Arbitrarily Shaped Objects</a>.
