Detailed Description

extract geometry for structured points.

Date:

2001/11/01 18:02:49

Revision:

1.1

vtkImageDataGeometryFilter is a filter that extracts geometry from a structured points dataset. By specifying appropriate i-j-k indices (via the "Extent" instance variable), it is possible to extract a point, a line, a plane (i.e., image), or a "volume" from dataset. (Since the output is of type polydata, 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 volume 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

virtual const char* vtkImageDataGeometryFilter::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 vtkStructuredPointsToPolyDataFilter. Reimplemented in vtkStructuredPointsGeometryFilter.

int vtkImageDataGeometryFilter::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 vtkStructuredPointsToPolyDataFilter. Reimplemented in vtkStructuredPointsGeometryFilter.

virtual int vtkImageDataGeometryFilter::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 vtkStructuredPointsToPolyDataFilter. Reimplemented in vtkStructuredPointsGeometryFilter.

vtkImageDataGeometryFilter* vtkImageDataGeometryFilter::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 vtkStructuredPointsToPolyDataFilter. Reimplemented in vtkStructuredPointsGeometryFilter.

void vtkImageDataGeometryFilter::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.

vtkImageDataGeometryFilter* vtkImageDataGeometryFilter::New (    )  [static]

Construct with initial extent of all the data Reimplemented from vtkPolyDataSource. Reimplemented in vtkStructuredPointsGeometryFilter.

void vtkImageDataGeometryFilter::SetExtent (  int    extent[6] )

Set / get the extent (imin,imax, jmin,jmax, kmin,kmax) indices.

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

Set / get the extent (imin,imax, jmin,jmax, kmin,kmax) indices.

int* vtkImageDataGeometryFilter::GetExtent (    )  [inline]

Set / get the extent (imin,imax, jmin,jmax, kmin,kmax) indices. Definition at line 90 of file vtkImageDataGeometryFilter.h.

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

This method is the old style execute method Reimplemented from vtkSource.
