Detailed Description

topologically regular array of data.

Date:
2000/12/10 20:08:18
Revision:
1.75

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.

Examples:

Member Function Documentation

void vtkStructuredGrid::BlankingOn  
 

Methods for supporting blanking of cells.

void vtkStructuredGrid::CopyStructure vtkDataSet   ds [virtual]
 

Copy the geometric and topological structure of an input poly data object.

Reimplemented from vtkPointSet.

unsigned long vtkStructuredGrid::GetActualMemorySize   [virtual]
 

Return the actual size of the data in kilobytes. This number is valid only after the pipeline has updated. The memory size returned is guaranteed to be greater than or equal to the memory required to represent the data (e.g., extra space in arrays, etc. are not included in the return value). THIS METHOD IS THREAD SAFE.

Reimplemented from vtkPointSet.

void vtkStructuredGrid::GetCell int    cellId,
vtkGenericCell   cell
[virtual]
 

Get cell with cellId such that: 0 <= cellId < NumberOfCells. This is a thread-safe alternative to the previous GetCell() method. THIS METHOD IS THREAD SAFE IF FIRST CALLED FROM A SINGLE THREAD AND THE DATASET IS NOT MODIFIED

Implements vtkDataSet.

vtkCell* vtkStructuredGrid::GetCell int    cellId [virtual]
 

Get cell with cellId such that: 0 <= cellId < NumberOfCells. THIS METHOD IS NOT THREAD SAFE.

Implements vtkDataSet.

void vtkStructuredGrid::GetCellBounds int    cellId,
float    bounds[6]
[virtual]
 

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. THIS METHOD IS THREAD SAFE IF FIRST CALLED FROM A SINGLE THREAD AND THE DATASET IS NOT MODIFIED

Reimplemented from vtkDataSet.

void vtkStructuredGrid::GetCellNeighbors int    cellId,
vtkIdList   ptIds,
vtkIdList   cellIds
[virtual]
 

Topological inquiry to get all cells using list of points exclusive of cell specified (e.g., cellId). THIS METHOD IS THREAD SAFE IF FIRST CALLED FROM A SINGLE THREAD AND THE DATASET IS NOT MODIFIED

Reimplemented from vtkDataSet.

void vtkStructuredGrid::GetCellPoints int    cellId,
vtkIdList   ptIds
[inline]
 

For legacy compatibility. Do not use.

Reimplemented from vtkDataSet.

void vtkStructuredGrid::GetCellPoints int    cellId,
vtkIdList   ptIds
[virtual]
 

Topological inquiry to get points defining cell. THIS METHOD IS THREAD SAFE IF FIRST CALLED FROM A SINGLE THREAD AND THE DATASET IS NOT MODIFIED

Implements vtkDataSet.

int vtkStructuredGrid::GetCellType int    cellId [virtual]
 

Get type of cell with cellId such that: 0 <= cellId < NumberOfCells. THIS METHOD IS THREAD SAFE IF FIRST CALLED FROM A SINGLE THREAD AND THE DATASET IS NOT MODIFIED

Implements vtkDataSet.

virtual const char* vtkStructuredGrid::GetClassName   [virtual]
 

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkPointSet.

int vtkStructuredGrid::GetDataDimension   [inline]
 

Return the dimensionality of the data.

int vtkStructuredGrid::GetDataObjectType   [inline, virtual]
 

Return what type of dataset this is.

Reimplemented from vtkDataSet.

virtual int* vtkStructuredGrid::GetDimensions   [virtual]
 

Get dimensions of this structured points dataset.

int vtkStructuredGrid::GetMaxCellSize   [inline, virtual]
 

Convenience method returns largest cell size in dataset. This is generally used to allocate memory for supporting data structures. THIS METHOD IS THREAD SAFE

Implements vtkDataSet.

int vtkStructuredGrid::GetNumberOfCells   [inline, virtual]
 

Determine the number of cells composing the dataset. THIS METHOD IS THREAD SAFE

Implements vtkDataSet.

int vtkStructuredGrid::GetNumberOfPoints   [inline, virtual]
 

Standard vtkDataSet API methods. See vtkDataSet for more information.

Reimplemented from vtkPointSet.

void vtkStructuredGrid::GetPoint int    ptId,
float    p[3]
[inline, virtual]
 

Copy point coordinates into user provided array x[3] for specified point id. THIS METHOD IS THREAD SAFE IF FIRST CALLED FROM A SINGLE THREAD AND THE DATASET IS NOT MODIFIED

Reimplemented from vtkPointSet.

float* vtkStructuredGrid::GetPoint int    ptId [inline, virtual]
 

Get point coordinates with ptId such that: 0 <= ptId < NumberOfPoints. THIS METHOD IS NOT THREAD SAFE.

Reimplemented from vtkPointSet.

void vtkStructuredGrid::GetPointCells int    ptId,
vtkIdList   cellIds
[inline, virtual]
 

Topological inquiry to get cells using point. THIS METHOD IS THREAD SAFE IF FIRST CALLED FROM A SINGLE THREAD AND THE DATASET IS NOT MODIFIED

Implements vtkDataSet.

void vtkStructuredGrid::Initialize   [virtual]
 

Reset to an empty state and free any memory.

Reimplemented from vtkPointSet.

virtual int vtkStructuredGrid::IsA const char *    type [virtual]
 

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkPointSet.

int vtkStructuredGrid::IsPointVisible int    ptId [inline]
 

Return non-zero value if specified point is visible.

int vtkStructuredGrid::IsTypeOf const char *    type [static]
 

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkPointSet.

vtkDataObject* vtkStructuredGrid::MakeObject   [inline, virtual]
 

Create a similar type object

Reimplemented from vtkDataObject.

vtkStructuredGrid* vtkStructuredGrid::New   [static]
 

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkDataObject.

void vtkStructuredGrid::PrintSelf ostream &    os,
vtkIndent    indent
[virtual]
 

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkPointSet.

vtkStructuredGrid* vtkStructuredGrid::SafeDownCast vtkObject   o [static]
 

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkPointSet.

void vtkStructuredGrid::SetDimensions int    i,
int    j,
int    k
 

following methods are specific to structured grid

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).

void vtkStructuredGrid::SetUpdateExtent int    x1,
int    x2,
int    y1,
int    y2,
int    z1,
int    z2

Call superclass method to avoid hiding

Reimplemented from vtkDataObject.

void vtkStructuredGrid::SetUpdateExtent int    piece,
int    numPieces,
int    ghostLevel
 

Required for the lowest common denominator for setting the UpdateExtent (i.e. vtkDataSetToStructuredPointsFilter). This assumes that WholeExtent is valid (UpdateInformation has been called).

void vtkStructuredGrid::ShallowCopy vtkDataObject   src [virtual]
 

Shallow and Deep copy.

Reimplemented from vtkPointSet.
