Detailed Description

CellArray generic array of cells

CellArray is a generic container that allows to deal with various cell layouts in memory

Triangulation
ttkTriangulation This version assumes the cell data to be given as a unique array. This array contains for each cell the number of points in the cell then the point ids of the cell. See VTK 8.2 vtkCellArray documentation for more details about this layout. This file will be installed by CMake as CellArray.h if the TTK_CELL_ARRAY_LAYOUT is set to SingleArray

CellArray is a generic container that allows to deal with various cell layouts in memory

See also
Triangulation
ttkTriangulation This version assumes the cell data to be given by two arrays:
  • Connectivity, containing the list of point ids of each cells
  • Offsets, containing the beginning and end position of each cell in the Connectivity array See VTK 9 vtkCellArray documentation for more details about this layout. This class is more a view on data than a complete container. It does not support memory modification operations. This file will be installed by CMake as CellArray.h if the TTK_CELL_ARRAY_LAYOUT is set to OffsetAndConnectivity

Member Function Documentation

◆ getCellVertex() [1/2]

LongSimplexId ttk::CellArray::getCellVertex ( const LongSimplexId  cellId,
const SimplexId  localVertId 
) const
inline

Get the vertex id of the "localVertId"'nt vertex of the cell.

Parameters
cellIdglobal id of the cell
localVertIdid of the vertex local to the cell, usually lower than 4 in 3D and lower than 3 in 2D.
Returns
the global id of the vertex

Definition at line 78 of file CellArray_legacy.h.

◆ getCellVertex() [2/2]

LongSimplexId ttk::CellArray::getCellVertex ( const LongSimplexId  cellId,
const SimplexId  localVertId 
) const
inline

Get the vertex id of the "localVertId"'nt vertex of the cell. Can deal with heterogeneous meshes

Parameters
cellIdglobal id of the cell
localVertIdid of the vertex local to the cell
Returns
the global id of the vertex

Definition at line 78 of file CellArray_new.h.

◆ getCellVertexNumber() [1/2]

SimplexId ttk::CellArray::getCellVertexNumber ( const LongSimplexId  cellId) const
inline

Get the number of vertices in the cell with the id: cellid

Parameters
cellIdglobal id of the cell
Returns
dimension + 1 for now as we only accept regular meshes

Definition at line 63 of file CellArray_legacy.h.

◆ getCellVertexNumber() [2/2]

SimplexId ttk::CellArray::getCellVertexNumber ( const LongSimplexId  cellId) const
inline

Get the number of vertices in the cell with the id: cellid Can deal with heterogeneous meshes

Parameters
cellIdglobal id of the cell
Returns
the offset difference between this cell and next.

Definition at line 63 of file CellArray_new.h.

◆ getDimension()

unsigned char ttk::CellArray::getDimension ( ) const
inline

Retrieve the dimension.

inline

Get the number of cells in the array.

Definition at line 56 of file CellArray_legacy.h.

◆ getNbCells() [2/2]

LongSimplexId ttk::CellArray::getNbCells ( ) const
inline

Get the number of cells in the array.

Definition at line 55 of file CellArray_new.h.

◆ setOwnership() [1/2]

void ttk::CellArray::setOwnership ( const bool  o)
inline

Definition at line 46 of file CellArray_legacy.h.

◆ setOwnership() [2/2]

void ttk::CellArray::setOwnership ( const bool  o)
inline

Deal with data ownership.

Definition at line 50 of file CellArray_new.h.
