Definition

template<class LCC>
class CGAL::Linear_cell_complex_incremental_builder_3< LCC >

The auxiliary class Linear_cell_complex_incremental_builder_3 supports the incremental construction of linear cell complexes.

Template Parameters

LCC	must be a model of the concept LinearCellComplex

Examples

Linear_cell_complex/linear_cell_complex_3_incremental_builder.cpp.

Public Types

typedef LCC::size_type	size_type

Creation
	Linear_cell_complex_incremental_builder_3 (LCC &alcc)
	Constructor.

Surface Creation
To build a linear cell complex, the following regular expression gives the correct and allowed order and nesting of method calls from this section: begin_surface ( add_vertex | ( begin_facet add_vertex_to_facet end_facet ) ) end_surface When an edge is added in a facet, if the same edge exists in another facet of the same surface, then the two facets are glued along this edge. When a facet is added, if the same facet exists in another surface, the two surfaces are glued along this facet.
void	begin_surface ()
	starts a new surface.
VAH	add_vertex (const Point_3 &p)
	adds a new vertex for p and returns its handle.
void	begin_facet ()
	starts a new facet.
void	add_vertex_to_facet (size_type i)
	adds vertex i at the end of the current facet.
DH	end_facet ()
	ends the construction of the facet and returns the first dart of this facet.
DH	end_surface ()
	ends the construction of the surface and returns one dart of the created surface.

Additional Operations
DH	add_facet (std::initializer_list< size_type > l)
	is a synonym for begin_facet(), a call to add_vertex_to_facet() for each value in the range [first,beyond), and a call to end_facet().
