Member Typedef Documentation

◆ Construct_anchor_point_3

A constructor object which provides the following function operator:

Point operator()(const Point &center_del, const Point &center_vor);

Constructs the anchor point in between the Delaunay and Voronoi centers, i.e., the point \( (1-s)\cdot\)center_del + \( s\cdot\)center_vor, where \( s\) is the shrink factor.

Constructor & Destructor Documentation

◆ SkinSurfaceTraits_3()

SkinSurfaceTraits_3::SkinSurfaceTraits_3 ( RT  s = .5)

Constructor that takes the shrink factor as argument.

For meshing the boundary of the union of a set of balls, the shrink factor is discarded.
