Detailed Description

Builds the space leaping data structure.

This is an optimized multi-threaded imaging filter that builds the space leaping datastructure, used by vtkFixedPointVolumeRayCastMapper. Empty space leaping is used to skip large empty regions in the scalar opacity and/or the gradient opacity transfer functions. Depending on the various options set by vtkFixedPointVolumeRayCastMapper, the class will internally invoke one of the many optimized routines to compute the min/max/gradient-max values within a fixed block size, trying to compute everything in a single multi-threaded pass through the data

The block size may be changed at compile time. Its ifdef'ed to 4 in the CXX file.

◆ SetGradientMagnitude()

void vtkVolumeRayCastSpaceLeapingImageFilter::SetGradientMagnitude ( unsigned char **  gradientMagnitude)

Pointer to the pre-computed gradient magnitude structure.

This is pre- computed by the vtkFixedPointVolumeRayCastMapper class. This should be set if one has the ComputeGradientOpacity flag enabled.

◆ GetGradientMagnitude()

unsigned char ** vtkVolumeRayCastSpaceLeapingImageFilter::GetGradientMagnitude ( )

Pointer to the pre-computed gradient magnitude structure.

This is pre- computed by the vtkFixedPointVolumeRayCastMapper class. This should be set if one has the ComputeGradientOpacity flag enabled.

◆ SetScalarOpacityTable()

void vtkVolumeRayCastSpaceLeapingImageFilter::SetScalarOpacityTable ( int  c,
unsigned short *  t 
)

Set the scalar opacity and gradient opacity tables computed for each component by the vtkFixedPointVolumeRayCastMapper.

◆ SetGradientOpacityTable()

void vtkVolumeRayCastSpaceLeapingImageFilter::SetGradientOpacityTable ( int  c,
unsigned short *  t 
)

Set the scalar opacity and gradient opacity tables computed for each component by the vtkFixedPointVolumeRayCastMapper.

◆ ComputeOffset()

vtkIdType vtkVolumeRayCastSpaceLeapingImageFilter::ComputeOffset ( const int  ext[6],
const int  wholeExt[6],
int  nComponents 
)

INTERNAL - Do not use Compute the offset within an image of whole extents wholeExt, to access the data starting at extents ext.

See superclass for details.

Reimplemented from vtkThreadedImageAlgorithm.

◆ RequestData()

int vtkVolumeRayCastSpaceLeapingImageFilter::RequestData ( vtkInformation request,
vtkInformationVector **  inputVector,
vtkInformationVector outputVector 
)
overrideprotectedvirtual

)
overrideprotectedvirtual

See superclass for details.

Reimplemented from vtkImageAlgorithm.

◆ ComputeFirstNonZeroOpacityIndices()

void vtkVolumeRayCastSpaceLeapingImageFilter::ComputeFirstNonZeroOpacityIndices ( )
protected

Compute the first non-zero scalar opacity and gradient opacity values that are encountered when marching from the beginning of the transfer function tables.

◆ FillScalarOpacityFlags()

void vtkVolumeRayCastSpaceLeapingImageFilter::FillScalarOpacityFlags ( vtkImageData minMaxVolume,
int  outExt[6] 
)
protected

Fill the flags after processing the min/max/gradient structure.

This optimized version is invoked when only scalar opacity table is needed.

◆ FillScalarAndGradientOpacityFlags()

void vtkVolumeRayCastSpaceLeapingImageFilter::FillScalarAndGradientOpacityFlags ( vtkImageData minMaxVolume,
int  outExt[6] 
)
protected

Fill the flags after processing the min/max/gradient structure.

This optimized version is invoked when both scalar and gradient opacity tables need to be visited.

◆ AllocateOutputData() [1/2]

void vtkVolumeRayCastSpaceLeapingImageFilter::AllocateOutputData ( vtkImageData out,
vtkInformation outInfo,
int *  uExtent 
)
overrideprotectedvirtual

Allocate the output data.

If we have a cache with the same metadata as the output we are going to generate, re-use the cache as we may not be updating all data in the min-max structure.

Reimplemented from vtkImageAlgorithm.

◆ AllocateOutputData() [2/2]

vtkImageData * vtkVolumeRayCastSpaceLeapingImageFilter::AllocateOutputData ( vtkDataObject out,
vtkInformation outInfo 
)
overrideprotectedvirtual

Allocate the output data.

If we have a cache with the same metadata as the output we are going to generate, re-use the cache as we may not be updating all data in the min-max structure.

Reimplemented from vtkImageAlgorithm.
