Detailed Description

topologically regular array of data

vtkStructuredGrid is a data object that is a concrete implementation of vtkDataSet. vtkStructuredGrid represents a geometric structure that is a topologically regular array of points. The topology is that of a cube that has been subdivided into a regular array of smaller cubes. Each point/cell can be addressed with i-j-k indices. Examples include finite difference grids.

The order and number of points must match that specified by the dimensions of the grid. The point order increases in i fastest (from 0<=i<dims[0]), then j (0<=j<dims[1]), then k (0<=k<dims[2]) where dims[] are the dimensions of the grid in the i-j-k topological directions. The number of points is dims[0]*dims[1]*dims[2]. The same is true for the cells of the grid. The order and number of cells must match that specified by the dimensions of the grid. The cell order increases in i fastest (from 0<=i<(dims[0]-1)), then j (0<=j<(dims[1]-1)), then k (0<=k<(dims[2]-1)) The number of cells is (dims[0]-1)*(dims[1]-1)*(dims[2]-1).

vtkStructuredGrid has the ability to blank, or "turn-off" points and cells in the dataset. This is done by setting vtkDataSetAttributes::HIDDENPOINT or vtkDataSetAttributes::HIDDENCELL in the ghost array for each point / cell that needs to be blanked.

◆ GetCell() [3/3]

void vtkStructuredGrid::GetCell ( vtkIdType  cellId,
vtkGenericCell cell

overridevirtual

Get cell with cellId such that: 0 <= cellId < NumberOfCells.

◆ GetCellBounds()

void vtkStructuredGrid::GetCellBounds ( vtkIdType  cellId,
double  bounds[6]

overridevirtual

Get the bounds of the cell with cellId such that: 0 <= cellId < NumberOfCells.

A subclass may be able to determine the bounds of cell without using an expensive GetCell() method. A default implementation is provided that actually uses a GetCell() call. This is to ensure the method is available to all datasets. Subclasses should override this method to provide an efficient implementation.

◆ SetExtent() [1/2]

void vtkStructuredGrid::SetExtent ( int  extent[6])

Different ways to set the extent of the data array.

The extent should be set before the "Scalars" are set or allocated. The Extent is stored in the order (X, Y, Z).

◆ BlankPoint()

void vtkStructuredGrid::BlankPoint ( vtkIdType  ptId)

Blanking turns on or off points in the structured grid, and hence the cells connected to them. These methods should be called only after the dimensions of the grid are set.

◆ UnBlankPoint()

void vtkStructuredGrid::UnBlankPoint ( vtkIdType  ptId)

◆ BlankCell()

void vtkStructuredGrid::BlankCell ( vtkIdType  ptId)

Methods for supporting blanking of cells.

Blanking turns on or off cells in the structured grid, and hence the points connected to them. These methods should be called only after the dimensions of the grid are set.

◆ UnBlankCell()

void vtkStructuredGrid::UnBlankCell ( vtkIdType  ptId)

◆ IsPointVisible()

unsigned char vtkStructuredGrid::IsPointVisible ( vtkIdType  ptId)

Return non-zero value if specified point is visible.

These methods should be called only after the dimensions of the grid are set.

◆ IsCellVisible()

unsigned char vtkStructuredGrid::IsCellVisible ( vtkIdType  cellId)

Return non-zero value if specified point is visible.

These methods should be called only after the dimensions of the grid are set.

Reimplemented from vtkDataSet.

◆ GetCellDims()

void vtkStructuredGrid::GetCellDims ( int  cellDims[3])

Given the node dimensions of this grid instance, this method computes the node dimensions.

The value in each dimension can will have a lowest value of "1" such that computing the total number of cells can be achieved by simply by cellDims[0]*cellDims[1]*cellDims[2].

◆ Crop()

void vtkStructuredGrid::Crop ( const int *  updateExtent)
overridevirtual

Reallocates and copies to set the Extent to the UpdateExtent.

This is used internally when the exact extent is requested, and the source generated more than the update extent.

Reimplemented from vtkDataObject.

◆ GetData() [1/2]

static vtkStructuredGrid* vtkStructuredGrid::GetData ( vtkInformation info)
static

Retrieve an instance of this class from an information object.

◆ GetData() [2/2]

◆ GetPoint() [3/3]

void vtkStructuredGrid::GetPoint ( int  i,
int  j,
int  k,
double  p[3],
bool  adjustForExtent = true 
)

Get a point in the grid.

If adjustForExtent is true, (i,j,k) is interpreted as a position relative to the beginning of the extent. If adjustForExtent is false, (i,j,k) is interpreted literally and the (i,j,k) point of the grid is returned regardless of the extent beginning. The point coordinate is returned in 'p'. The default adjustForExtent is true.

◆ ComputeScalarRange()

void vtkStructuredGrid::ComputeScalarRange ( )
overrideprotectedvirtual

Compute the range of the scalars and cache it into ScalarRange only if the cache became invalid (ScalarRangeComputeTime).
