Detailed Description

extract geometry for structured grid.

Date:

2000/12/10 20:08:53

Revision:

1.35

vtkStructuredGridGeometryFilter is a filter that extracts geometry from a structured grid. By specifying appropriate i-j-k indices, it is possible to extract a point, a curve, a surface, or a "volume". Depending upon the type of data, the curve and surface may be curved or planar. 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 structured 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

vtkStructuredGridGeometryFilter* vtkStructuredGridGeometryFilter::New (    )  [static]

Instantiate object with no start, end, or progress methods. Reimplemented from vtkPolyDataSource.

virtual const char* vtkStructuredGridGeometryFilter::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 vtkStructuredGridToPolyDataFilter.

int vtkStructuredGridGeometryFilter::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 vtkStructuredGridToPolyDataFilter.

virtual int vtkStructuredGridGeometryFilter::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 vtkStructuredGridToPolyDataFilter.

vtkStructuredGridGeometryFilter* vtkStructuredGridGeometryFilter::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 vtkStructuredGridToPolyDataFilter.

void vtkStructuredGridGeometryFilter::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 vtkSource.

virtual int* vtkStructuredGridGeometryFilter::GetExtent (    )  [virtual]

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

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

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

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

void vtkStructuredGridGeometryFilter::SetExtent (  int *    extent )

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

void vtkStructuredGridGeometryFilter::operator= (  const vtkStructuredGridGeometryFilter &    )  [inline, protected]

Definition at line 94 of file vtkStructuredGridGeometryFilter.h.

void vtkStructuredGridGeometryFilter::Execute (    )  [protected, virtual]

Reimplemented from vtkSource.
