Detailed Description

RVDVertexMap maps symbolic vertices to unique ids.

Symbolic vertices are manipulated by GEOGen::RestrictedVoronoiDiagram. This class is used for instance in the implementation of RVDMeshBuilder.

Note
This is an internal implementation class, not meant to be used directly, use GEO::RestrictedVoronoiDiagram instead.

Member Function Documentation

◆ find_or_create_vertex()

index_t GEO::RVDVertexMap::find_or_create_vertex ( index_t  center_vertex_id,
const SymbolicVertex sym 
)

Maps the symbolic information of a vertex into a unique identifier.

Parameters
[in]center_vertex_idthe index of the current Voronoi seed (provided by action classes in GEOGen::RestrictedVoronoiDiagram)
[in]symthe symbolic representation of the vertex (provided by action classes in GEOGen::RestrictedVoronoiDiagram)
Returns
a unique identifier for this vertex

◆ set_first_vertex_index()

void GEO::RVDVertexMap::set_first_vertex_index ( index_t  i)
inline

Defines the index of the first created vertex.

Parameters
[in]iindex of the first vertex that will be created (default is 0).
