Template Parameters
LCCmust be a model of the concept LinearCellComplex
Examples
Linear_cell_complex/linear_cell_complex_3_incremental_builder.cpp.

Public Types

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:

DH end_surface()
ends the construction of the surface and returns one dart of the created surface.
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.
VAH add_vertex(const Point_3 &p)
adds a new vertex for p and returns its handle.

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().
