Detailed Description

select piece (e.g., volume of interest) and/or subsample structured points dataset

vtkExtractVOI is a filter that selects a portion of an input structured points dataset, or subsamples an input dataset. (The selected portion of interested is referred to as the Volume Of Interest, or VOI.) The output of this filter is a structured points dataset. The filter treats input data of any topological dimension (i.e., point, line, image, or volume) and can generate output data of any topological dimension.

To use this filter set the VOI ivar which are i-j-k min/max indices that specify a rectangular region in the data. (Note that these are 0-offset.) You can also specify a sampling rate to subsample the data.

Typical applications of this filter are to extract a slice from a volume for image processing, subsampling large volumes to reduce data size, or extracting regions of a volume with interesting data.

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.

Specify i-j-k (min,max) pairs to extract. The resulting structured points dataset can be of any topological dimension (i.e., point, line, image, or volume).

virtual void vtkExtractVOI::SetVOI ( int  [6])
virtual

Specify i-j-k (min,max) pairs to extract. The resulting structured points dataset can be of any topological dimension (i.e., point, line, image, or volume).

virtual int* vtkExtractVOI::GetVOI ( )

Specify i-j-k (min,max) pairs to extract. The resulting structured points dataset can be of any topological dimension (i.e., point, line, image, or volume).

virtual void vtkExtractVOI::GetVOI ( int  data[6])

Specify i-j-k (min,max) pairs to extract. The resulting structured points dataset can be of any topological dimension (i.e., point, line, image, or volume).

virtual void vtkExtractVOI::SetSampleRate ( int  ,
int  ,
int   
)
virtual

Set the sampling rate in the i, j, and k directions. If the rate is > 1, then the resulting VOI will be subsampled representation of the input. For example, if the SampleRate=(2,2,2), every other point will be selected, resulting in a volume 1/8th the original size.

virtual void vtkExtractVOI::SetSampleRate ( int  [3])
virtual

Set the sampling rate in the i, j, and k directions. If the rate is > 1, then the resulting VOI will be subsampled representation of the input. For example, if the SampleRate=(2,2,2), every other point will be selected, resulting in a volume 1/8th the original size.

virtual int* vtkExtractVOI::GetSampleRate ( )
virtual

Set the sampling rate in the i, j, and k directions. If the rate is > 1, then the resulting VOI will be subsampled representation of the input. For example, if the SampleRate=(2,2,2), every other point will be selected, resulting in a volume 1/8th the original size.

virtual void vtkExtractVOI::GetSampleRate ( int  data[3])
virtual

Set the sampling rate in the i, j, and k directions. If the rate is > 1, then the resulting VOI will be subsampled representation of the input. For example, if the SampleRate=(2,2,2), every other point will be selected, resulting in a volume 1/8th the original size.

virtual void vtkExtractVOI::SetIncludeBoundary ( int  )
virtual

Control whether to enforce that the "boundary" of the grid is output in the subsampling process. (This ivar only has effect when the SampleRate in any direction is not equal to 1.) When this ivar IncludeBoundary is on, the subsampling will always include the boundary of the grid even though the sample rate is not an even multiple of the grid dimensions. (By default IncludeBoundary is off.)

virtual int vtkExtractVOI::GetIncludeBoundary ( )
virtual

Control whether to enforce that the "boundary" of the grid is output in the subsampling process. (This ivar only has effect when the SampleRate in any direction is not equal to 1.) When this ivar IncludeBoundary is on, the subsampling will always include the boundary of the grid even though the sample rate is not an even multiple of the grid dimensions. (By default IncludeBoundary is off.)

virtual void vtkExtractVOI::IncludeBoundaryOn ( )
virtual

Control whether to enforce that the "boundary" of the grid is output in the subsampling process. (This ivar only has effect when the SampleRate in any direction is not equal to 1.) When this ivar IncludeBoundary is on, the subsampling will always include the boundary of the grid even though the sample rate is not an even multiple of the grid dimensions. (By default IncludeBoundary is off.)

virtual void vtkExtractVOI::IncludeBoundaryOff ( )
virtual

Control whether to enforce that the "boundary" of the grid is output in the subsampling process. (This ivar only has effect when the SampleRate in any direction is not equal to 1.) When this ivar IncludeBoundary is on, the subsampling will always include the boundary of the grid even though the sample rate is not an even multiple of the grid dimensions. (By default IncludeBoundary is off.)

virtual int vtkExtractVOI::RequestUpdateExtent ( vtkInformation *  ,
vtkInformationVector **  ,
vtkInformationVector *   
)
protectedvirtual

Subclasses can reimplement this method to translate the update extent requests from each output port into update extent requests for the input connections.

Reimplemented from vtkImageAlgorithm.

Reimplemented in vtkPExtractVOI.

virtual int vtkExtractVOI::RequestInformation ( vtkInformation *  request,
vtkInformationVector **  inputVector,
vtkInformationVector *  outputVector 
)
protectedvirtual

Subclasses can reimplement this method to collect information from their inputs and set information for their outputs.

Reimplemented from vtkImageAlgorithm.

Reimplemented in vtkPExtractVOI.

virtual int vtkExtractVOI::RequestData ( vtkInformation *  request,
vtkInformationVector **  inputVector,
vtkInformationVector *  outputVector 
)
protectedvirtual

This is called in response to a REQUEST_DATA request from the executive. Subclasses should override either this method or the ExecuteDataWithInformation method in order to generate data for their outputs. For images, the output arrays will already be allocated, so all that is necessary is to fill in the voxel values.

Reimplemented from vtkImageAlgorithm.

Reimplemented in vtkPExtractVOI.

bool vtkExtractVOI::RequestDataImpl ( int  voi[6],
vtkInformationVector **  inputVector,
vtkInformationVector *  outputVector 
)
protected

Implementation for RequestData using a specified VOI. This is because the parallel filter needs to muck around with the VOI to get spacing and partitioning to play nice.
