Detailed Description

extract geometry for a rectilinear grid

vtkRectilinearGridGeometryFilter is a filter that extracts geometry from a rectilinear grid. By specifying appropriate i-j-k indices, it is possible to extract a point, a curve, a surface, or a "volume". The volume is actually a (n x m x o) region of points.

The extent specification is zero-offset. That is, the first k-plane in a 50x50x50 rectilinear grid is given by (0,49, 0,49, 0,0).

Warning:
If you don't know the dimensions of the input dataset, you can use a large number to specify extent (the number will be clamped appropriately). For example, if the dataset dimensions are 50x50x50, and you want a the fifth k-plane, you can use the extents (0,100, 0,100, 4,4). The 100 will automatically be clamped to 49.

Member Function Documentation

static int vtkRectilinearGridGeometryFilter::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 vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkPolyDataAlgorithm.

virtual int vtkRectilinearGridGeometryFilter::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 vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkPolyDataAlgorithm.

Reimplemented from vtkPolyDataAlgorithm.

void vtkRectilinearGridGeometryFilter::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 vtkPolyDataAlgorithm.

Construct with initial extent (0,100, 0,100, 0,0) (i.e., a k-plane).

Reimplemented from vtkPolyDataAlgorithm.

Get the extent in topological coordinate range (imin,imax, jmin,jmax, kmin,kmax).

virtual void vtkRectilinearGridGeometryFilter::GetExtent ( int  data[6]) [virtual]

Get the extent in topological coordinate range (imin,imax, jmin,jmax, kmin,kmax).

void vtkRectilinearGridGeometryFilter::SetExtent ( int  iMin,
int  iMax,
int  jMin,
int  jMax,
int  kMin,
int  kMax 
)

Specify (imin,imax, jmin,jmax, kmin,kmax) indices.

Specify (imin,imax, jmin,jmax, kmin,kmax) indices in array form.

virtual int vtkRectilinearGridGeometryFilter::RequestData ( vtkInformation request,
vtkInformationVector **  inputVector,
vtkInformationVector outputVector 
) [protected, virtual]

This is called by the superclass. This is the method you should override.

Reimplemented from vtkPolyDataAlgorithm.

virtual int vtkRectilinearGridGeometryFilter::FillInputPortInformation ( int  port,
vtkInformation info 
) [protected, virtual]

Fill the input port information objects for this algorithm. This is invoked by the first call to GetInputPortInformation for each port so subclasses can specify what they can handle.

Reimplemented from vtkPolyDataAlgorithm.
