Abstract
A method is presented for meshing 3D CAD surfaces in parametric space using
an advancing front approach. A metric map is used to govern the size and
shape of the triangles in the parametric space. The advancing front mesher
generates triangles based on the metric map, stretching them, when needed,
in order to capture changes in parameterization of the surface. The benefits
of this algorithm include better quality elements without having to do costly
real space calculations, such as projections and 3D facet intersections.
