Detailed Description

vtkStructuredGridConnectivity is a concrete instance of vtkObject that implements functionality for computing the neighboring topology within a single partitioned structured grid dataset. This class implementation does not have any support for distributed data. For the parallel implementation see vtkPStructuredGridConnectivity.

void vtkStructuredGridConnectivity::CreateGhostedExtent ( const int  gridID,
const int  N 
)
protected

Creates the ghosted extent of the grid corresponding to the given gridID.

void vtkStructuredGridConnectivity::GetGhostedExtent ( int *  ghostedExtent,
int  GridExtent[6],
const int  minIdx,
const int  maxIdx,
const int  N 
)
inlineprotected

Gets the ghosted extent from the given grid extent along the dimension given by minIdx and maxIdx. This method is a helper method for the implementation of CreateGhostedExtent.

Definition at line 579 of file vtkStructuredGridConnectivity.h.

void vtkStructuredGridConnectivity::CreateGhostedMaskArrays ( const int  gridID)
protected

This method creates the ghosted mask arrays, i.e., the NodeGhostArrays and the CellGhostArrays for the grid corresponding to the given gridID.

void vtkStructuredGridConnectivity::InitializeGhostData ( const int  gridID)
protected

This method initializes the ghost data according to the computed ghosted grid extent for the grid with the given grid ID. Specifically, PointData, CellData and grid coordinates are allocated for the ghosted grid accordingly.

void vtkStructuredGridConnectivity::AllocatePointData ( vtkPointData *  RPD,
const int  N,
vtkPointData *  PD 
)
protected

Adds/creates all the arrays in the reference grid point data, RPD, to the user-supplied point data instance, PD, where the number of points is given by N.

void vtkStructuredGridConnectivity::AllocateCellData ( vtkCellData *  RCD,
const int  N,
vtkCellData *  CD 
)
protected

Adds/creates all the arrays in the reference grid cell data, RCD, to the user-supplied cell data instance, CD, where the number of cells is given by N.

void vtkStructuredGridConnectivity::TransferRegisteredDataToGhostedData ( const int  gridID)
protected

This method transfers the registered grid data to the corresponding ghosted grid data.

void vtkStructuredGridConnectivity::ComputeNeighborSendAndRcvExtent ( const int  gridID,
const int  N 
)
protected

This method computes, the send and rcv extents for each neighbor of each grid.

virtual void vtkStructuredGridConnectivity::TransferGhostDataFromNeighbors ( const int  gridID)
protectedvirtual

This method transfers the fields (point data and cell data) to the ghost extents from the neighboring grids of the grid corresponding to the given gridID.

Reimplemented in vtkPStructuredGridConnectivity.

void vtkStructuredGridConnectivity::TransferLocalNeighborData ( const int  gridID,
const vtkStructuredNeighbor &  Neighor 
)
protected

This method transfers the fields

void vtkStructuredGridConnectivity::CopyCoordinates ( vtkPoints *  source,
vtkIdType  sourceIdx,
vtkPoints *  target,
vtkIdType  targetIdx 
)
protected

Copies the coordinates from the source points to the target points.

void vtkStructuredGridConnectivity::CopyFieldData ( vtkFieldData *  source,
vtkIdType  sourceIdx,
vtkFieldData *  target,
vtkIdType  targetIdx 
)
protected

Loops through all arrays in the source and for each array, it copies the tuples from sourceIdx to the target at targetIdx. This method assumes that the source and target have a one-to-one array correspondance, that is array i in the source corresponds to array i in the target.

int vtkStructuredGridConnectivity::GetNeighborIndex ( const int  gridIdx,
const int  NeighborGridIdx 
)
inlineprotected

Given a global grid ID and the neighbor grid ID, this method returns the neighbor index w.r.t. the Neighbors list of the grid with grid ID gridIdx.

void vtkStructuredGridConnectivity::PrintExtent ( int  extent[6])
protected

Prints the extent, used for debugging
