[in] c the corner

Returns: a pointer to the the facet index that corner is adjacent to.

Definition at line 1021 of file mesh.h.

◆ adjacent_facet_ptr() [2/2]

inline

Gets a pointer to the the facet index that a corner is adjacent to.

Parameters

[in] c the corner

Returns: a pointer to the the facet index that corner is adjacent to.

Definition at line 1008 of file mesh.h.

◆ clear_store()

void GEO::MeshFacetCornersStore::clear_store	(	bool	keep_attributes,
		bool	keep_memory = `false`
	)

overrideprotectedvirtual

Removes all the elements and attributes.

Parameters

[in]	keep_attributes	if true, then all the existing attribute names / bindings are kept (but they are cleared). If false, they are destroyed.
[in]	keep_memory	if true, then memory is kept and can be reused by subsequent mesh element creations.

Reimplemented from GEO::MeshSubElementsStore.

template<index_t DIM = 3>

vecng< DIM, double > & GEO::MeshFacetCornersStore::point ( index_t c )

inline

Gets the point associated with a corner.

Parameters

[in] c the corner

overrideprotectedvirtual

Resizes this MeshSubElementsStore.

On exit, nb() == new_size, elements are created or destroyed if needed.

Parameters

[in] new_size the desired size

Reimplemented from GEO::MeshSubElementsStore.

◆ set_adjacent_facet()

void GEO::MeshFacetCornersStore::set_adjacent_facet	(	index_t	c,
		index_t	f
	)

inline

Sets the facet that a corner is adjacent to.

Parameters

[in]	c	the corner
[in]	f	the facet that corner `is` adjacent to or NO_FACET if `c` is on the border

Definition at line 1059 of file mesh.h.

◆ set_vertex()

void GEO::MeshFacetCornersStore::set_vertex	(	index_t	c,
		index_t	v
	)

inline

Sets the vertex that a corner is incident to.

Parameters

[in]	c	the corner
[in]	v	the vertex that corner `c` is incident to

Precondition: v < mesh.vertices.nb()

Definition at line 1032 of file mesh.h.

◆ set_vertex_no_check()

void GEO::MeshFacetCornersStore::set_vertex_no_check	(	index_t	c,
		index_t	v
	)

inline

Sets the vertex that a corner is incident to.

Does not check whether v is a valid vertex index. This function is useful for some algorithms that need to create/update the facets before creating the vertices.

Parameters

[in]	c	the corner
[in]	v	the vertex that corner `c` is incident to

Note: Normal uses do not call this function

Definition at line 1048 of file mesh.h.

◆ vertex()

index_t GEO::MeshFacetCornersStore::vertex ( index_t c ) const

inline

Gets the vertex that a corner is incident to.

Parameters

[in] c the corner

Returns: the vertex that corner c is incident to

Definition at line 985 of file mesh.h.

◆ vertex_index_ptr() [1/2]

index_t * GEO::MeshFacetCornersStore::vertex_index_ptr ( index_t c )

inline

Gets a pointer to the vertex that a corner is incident to.

Parameters

[in] c the corner

Returns: a pointer to the index of the vertex that this corner is incident to

Note: Normal uses do not call this function

Definition at line 1072 of file mesh.h.

◆ vertex_index_ptr() [2/2]

const index_t * GEO::MeshFacetCornersStore::vertex_index_ptr ( index_t c ) const

inline

Gets a pointer to the vertex that a corner is incident to.

Parameters

[in] c the corner

Definition at line 1084 of file mesh.h.

◆ vertex_indices()

const vector< index_t > & GEO::MeshFacetCornersStore::vertex_indices ( ) const

inline

Gets the vertex indices of all corners as a single vector.

On a triangulated mesh, this is the triangle list (3 vertex indices per facet). It is forbidden to change the size of the returned vector.

Returns: a const reference to the corner-to-vertex table.
