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 optmized 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.

Is the difference between max and min of the data less than 32768? If so, and if the data is not of float/double type, use a simple offset mapping. If the difference between max and min is 32768 or greater, or the data is of type float or double, we must use an offset / scaling mapping. In this case, the array size will be 32768 - we need to figure out the offset and scale factor.

int vtkVolumeRayCastSpaceLeapingImageFilter::GetNumberOfIndependentComponents ( )

Get the number of independent components for which we need to keep track of min/max

unsigned short* vtkVolumeRayCastSpaceLeapingImageFilter::GetMinMaxVolume ( int dims[4] )

Get the raw pointer to the final computed space leaping datastructure. The result is only valid after Update() has been called on the filter. Note that this filter holds onto its memory. The dimensions of the min- max volume are in dims. The 4th value in the array indicates the number of independent components, (also queried via GetNumberOfIndependentComponents())

virtual void vtkVolumeRayCastSpaceLeapingImageFilter::SetCache ( vtkImageData * imageCache )

virtual

INTERNAL - Do not use Set the last cached min-max volume, as used by vtkFixedPointVolumeRayCastMapper.

static

Compute the extents and dimensions of the input that's required to generate an output min-max structure given by outExt. INTERNAL - Do not use

unsigned short* vtkVolumeRayCastSpaceLeapingImageFilter::GetMinNonZeroScalarIndex ( )

Get the first non-zero scalar opacity and gradient opacity indices for each independent copmonent INTERNAL - Do not use.

unsigned char* vtkVolumeRayCastSpaceLeapingImageFilter::GetMinNonZeroGradientMagnitudeIndex ( )

Get the first non-zero scalar opacity and gradient opacity indices for each independent copmonent INTERNAL - Do not use.

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.

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.

void vtkVolumeRayCastSpaceLeapingImageFilter::SetScalarOpacityTable	(	int	c,

	)

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

		int	nComponents
