computes a watertight, 2-manifold, and intersection-free triangulated surface mesh that strictly contains an input triangle soup.
The parameters alpha and offset respectively control which features will appear in the output, and the distance from the input. See Section Choosing Parameters for a detailed breakdown of their influence.
Template Parameters
Parameters
points the input points faces the input faces, with each element of the range being a range of indices corresponding to points in points alpha the value of the parameter alpha offset the value of the parameter offset alpha_wrap the output surface mesh in_np an optional sequence of Named Parameters among the ones listed below
Optional Named Parameters
point_map
a property map associating points to the elements of the point set points
Type: a model of ReadablePropertyMap PointRange and whose value type is geom_traits::Point_3
Default: CGAL::Identity_property_map<geom_traits::Point_3>
geom_traits
an instance of a geometric traits class
Type: a class model of Kernel
Default: a CGAL Kernel deduced from the point type, using CGAL::Kernel_traits
Extra:
The geometric traits class must be compatible with the point type.
The geometric traits should use a floating point number type (see Interface ).
Parameters
Optional Named Parameters
vertex_point_map

Extra: If this parameter is omitted, an internal property map for CGAL::vertex_point_t must be available in OutputMesh.
Precondition The elements of faces are triangles.
alpha and offset are strictly positive values. Examples: Alpha_wrap_3/point_set_wrap.cpp , Alpha_wrap_3/triangle_mesh_wrap.cpp , and Alpha_wrap_3/triangle_soup_wrap.cpp .
