Detailed Description

Stores the facets of a mesh (low-level store)

Definition at line 753 of file mesh.h.

Member Function Documentation

◆ are_simplices()

bool GEO::MeshFacetsStore::are_simplices ( ) const
inline

Tests whether all the facets are triangles.

When all the facets are triangles, storage and access is optimized.

Return values
trueif all the facets are triangles
falseotherwise

Definition at line 809 of file mesh.h.

◆ clear_store()

void GEO::MeshFacetsStore::clear_store ( bool  keep_attributes,
bool  keep_memory = false 
)
overrideprotectedvirtual

Removes all the elements and attributes.

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

Reimplemented from GEO::MeshSubElementsStore.

◆ corner()

index_t GEO::MeshFacetsStore::corner ( index_t  f,
index_t  lv 
) const
inline

Gets a corner by facet and local vertex index.

Parameters
[in]fthe facet
[in]lvthe local index of the vertex in facet f
Returns
the lvth corner of facet f
Precondition
lv < nb_corners(f)

Definition at line 796 of file mesh.h.

◆ corners_begin()

index_t GEO::MeshFacetsStore::corners_begin ( index_t  f) const
inline

Gets the first element for iterating over the corners of a facet.

Parameters
[in]fthe facet
Returns
the first corner of the facet

Definition at line 763 of file mesh.h.

◆ corners_begin_ptr()

const index_t* GEO::MeshFacetsStore::corners_begin_ptr ( index_t  f) const
inline

Gets a pointer to the first element for iterating over the corners of a facet.

Parameters
[in]fthe facet
Returns
a pointer to the first corner of the facet

Definition at line 819 of file mesh.h.

◆ corners_end()

index_t GEO::MeshFacetsStore::corners_end ( index_t  f) const
inline

Gets the upper limit for iterating over the corners of a facet.

Parameters
[in]fthe facet
Returns
one position past the last corner of the facet

Definition at line 774 of file mesh.h.

◆ nb_corners()

index_t GEO::MeshFacetsStore::nb_corners ( index_t  f) const
inline

Gets the number of corners in a facet.

Parameters
[in]fthe facet
Returns
the number of corners in facet f

Definition at line 784 of file mesh.h.

◆ resize_store()

void GEO::MeshFacetsStore::resize_store ( index_t  new_size)
overrideprotectedvirtual

Resizes this MeshSubElementsStore.

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

Parameters
[in]new_sizethe desired size

Reimplemented from GEO::MeshSubElementsStore.
