Detailed Description

organize data according to scalar span space

This is a helper class used to accelerate contouring operations. Given an dataset, it organizes the dataset cells into a 2D binned space, with coordinate axes (scalar_min,scalar_max). This so-called span space can then be traversed quickly to find the cells that intersect a specified contour value.

This class has an API that supports both serial and parallel operation. The parallel API enables the using class to grab arrays (or batches) of cells that lie along a particular row in the span space. These arrays can then be processed separately or in parallel.

Learn more about span space in these two publications: 1) "A Near Optimal Isosorface Extraction Algorithm Using the Span Space." Yarden Livnat et al. and 2) Isosurfacing in Span Space with Utmost Efficiency." Han-Wei Shen et al.

◆ SetScalarRange() [1/2]

virtual void vtkSpanSpace::SetScalarRange ( double  ,
double   
)
virtual

Specify the scalar range in terms of minimum and maximum values (smin,smax).

These values are used to build the span space. Note that setting the range can have significant impact on the performance of the span space as it controls the effective resolution near important isocontour values. By default the range is computed automatically; turn off ComputeScalarRange is you wish to manually specify it.

◆ SetScalarRange() [2/2]

void vtkSpanSpace::SetScalarRange ( double  [2])

Specify the scalar range in terms of minimum and maximum values (smin,smax).

These values are used to build the span space. Note that setting the range can have significant impact on the performance of the span space as it controls the effective resolution near important isocontour values. By default the range is computed automatically; turn off ComputeScalarRange is you wish to manually specify it.

◆ GetScalarRange() [1/2]

virtual double* vtkSpanSpace::GetScalarRange ( )

By default the range is computed automatically; turn off ComputeScalarRange is you wish to manually specify it.

◆ SetComputeScalarRange()

virtual void vtkSpanSpace::SetComputeScalarRange ( vtkTypeBool  )
virtual

This boolean controls whether the determination of the scalar range is computed from the input scalar data.

By default this is enabled.

◆ GetComputeScalarRange()

virtual vtkTypeBool vtkSpanSpace::GetComputeScalarRange ( )

By default this is enabled.

◆ SetResolution()

virtual void vtkSpanSpace::SetResolution ( vtkIdType  )
virtual

Set/Get the resolution N of the span space.

The span space can be envisioned as a rectangular lattice of NXN buckets/bins (i.e., N rows and N columns), where each bucket stores a list of cell ids. The i-j coordinate of each cell (hence its location in the lattice) is determined from the cell's 2-tuple (smin,smax) scalar range. By default Resolution = 100, with a clamp of 10,000.

◆ GetResolution()

virtual vtkIdType vtkSpanSpace::GetResolution ( )
virtual

Set/Get the resolution N of the span space.

The span space can be envisioned as a rectangular lattice of NXN buckets/bins (i.e., N rows and N columns), where each bucket stores a list of cell ids. The i-j coordinate of each cell (hence its location in the lattice) is determined from the cell's 2-tuple (smin,smax) scalar range. By default Resolution = 100, with a clamp of 10,000.

virtual int vtkSpanSpace::GetNumberOfCellsPerBucket ( )
virtual

Specify the average number of cells in each bucket.

This is used to indirectly control the resolution if ComputeResolution is enabled.

Implements vtkScalarTree.

◆ InitTraversal()

void vtkSpanSpace::InitTraversal ( double  scalarValue)
overridevirtual

Begin to traverse the cells based on a scalar value.

Returned cells will have scalar values that span the scalar value specified (within the resolution of the span space). Note this method must be called prior to parallel or serial traversal since it specifies the scalar value to be extracted.

vtkIdList *&  ptIds,
vtkDataArray cellScalars 
)
overridevirtual

◆ GetCellBatch()

const vtkIdType* vtkSpanSpace::GetCellBatch ( vtkIdType  batchNum,
vtkIdType numCells 
)
overridevirtual

Return the array of cell ids in the specified batch.
