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).

A unusual feature of vtkStructuredGrid is the ability to blank, or "turn-off" points and cells in the dataset. This is controlled by defining a "blanking array" whose values (0,1) specify whether a point should be blanked or not.

Returns 1 if there is any visibility constraint on the cells, 0 otherwise.

virtual void vtkStructuredGrid::Crop (  )  [virtual]

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.

Retrieve an instance of this class from an information object.

Reimplemented from vtkPointSet.

static vtkStructuredGrid* vtkStructuredGrid::GetData ( vtkInformationVector v,

Retrieve an instance of this class from an information object.

Reimplemented from vtkPointSet.

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.
