CGAL 4.7 - 3D Skin Surface Meshing
|
The concept SkinSurface_3
defines a skin surface and provides an interface for the dedicated skin surface mesher. The concept requires a constructor from an iterator range of weighted points and a shrink factor. By default the input balls are grown in such that the skin surface wraps around the input balls.
