BLSURF - Mesh Generator for Composite Parametric Surfaces - User's Manual
Abstract
This technical report describes BLSURF, an automatic surface mesh generator. This software creates the mesh of a composite parametric surface while conforming to a prescribed size map. To this end, analytical functions defining the surface, as well as their first and possibly second derivatives, must be externally provided (for instance by a CAD system). Also, each patch must be described by giving its 2D parametric domain. The method used is based on an incremental Delaunay approach adapted to a Riemannian metric.
