Detailed Description

a dataset that is topologically regular with variable spacing in the three coordinate directions

vtkRectilinearGrid is a data object that is a concrete implementation of vtkDataSet. vtkRectilinearGrid represents a geometric structure that is topologically regular with variable spacing in the three coordinate directions x-y-z.

To define a vtkRectilinearGrid, you must specify the dimensions of the data and provide three arrays of values specifying the coordinates along the x-y-z axes. The coordinate arrays are specified using three vtkDataArray objects (one for x, one for y, one for z).

Warning:: Make sure that the dimensions of the grid match the number of coordinates in the x-y-z directions. If not, unpredictable results (including program failure) may result. Also, you must supply coordinates in all three directions, even if the dataset topology is 2D, 1D, or 0D.

Member Function Documentation

static vtkRectilinearGrid* vtkRectilinearGrid::New ( ) [static]

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

Reimplemented from vtkDataObject.

virtual const char* vtkRectilinearGrid::GetClassName ( ) [virtual]

Reimplemented from vtkDataSet.

static int vtkRectilinearGrid::IsTypeOf ( const char * name ) [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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkDataSet.

virtual int vtkRectilinearGrid::IsA ( const char * name ) [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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkDataSet.

static vtkRectilinearGrid* vtkRectilinearGrid::SafeDownCast ( vtkObject * o ) [static]

Reimplemented from vtkDataSet.

void vtkRectilinearGrid::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 vtkDataSet.

int vtkRectilinearGrid::GetDataObjectType ( ) [inline, virtual]

Return what type of dataset this is.

Reimplemented from vtkDataSet.

Definition at line 59 of file vtkRectilinearGrid.h.

void vtkRectilinearGrid::CopyStructure ( vtkDataSet * ds ) [virtual]

Copy the geometric and topological structure of an input rectilinear grid object.

Implements vtkDataSet.

void vtkRectilinearGrid::Initialize ( ) [virtual]

Restore object to initial state. Release memory back to system.

Reimplemented from vtkDataSet.
