## Member Function Documentation

## ◆ accessor()

const AccessorType & accessor | ( |  | ) | const
| inlineinherited

Return a const reference to the ValueAccessor associated with this Stencil.

## ◆ getCenterCoord()

const Coord & getCenterCoord | ( |  | ) | const
| inlineinherited

Return the coordinates of the center point of the stencil.

## ◆ getCenterValue()

const ValueType & getCenterValue | ( |  | ) | const
| inlineinherited

Return the value at the center of the stencil.

## ◆ getValue()

const ValueType & getValue | ( | unsigned int | pos = 0 | ) | const
| inlineinherited

Return the value from the stencil buffer with linear offset pos.

Note
  The default (pos = 0) corresponds to the first element which is typically the center point of the stencil.

## ◆ grid()

const GridType & grid | ( |  | ) | const
| inlineinherited

Return a const reference to the grid from which this stencil was constructed.

## ◆ intersectionMask()

std::bitset< 6 > intersectionMask | ( | const ValueType & | isoValue = zeroVal<ValueType>() | ) | const
| inlineinherited

Return true a bit-mask where the 6 bits indicates if the center of the stencil intersects the iso-contour specified by the isoValue.

Note
  There are 2^6 = 64 different possible cases, including no intersections!

The ordering of bit mask is ( -x, +x, -y, +y, -z, +z ), so to check if there is an intersection in -y use mask.test(2) where mask is ther return value from this function. To check if there are any intersections use mask.any(), and for no intersections use mask.none(). To count the number of intersections use mask.count().

## ◆ intersects()

bool intersects | ( | const ValueType & | isoValue = zeroVal<ValueType>() | ) | const
| inlineinherited

Return true if the center of the stencil intersects the iso-contour specified by the isoValue.

## ◆ max()

ValueType max | ( |  | ) | const
| inlineinherited

Return the largest value in the stencil buffer.

## ◆ mean()

ValueType mean | ( |  | ) | const
| inlineinherited

Return the mean value of the current stencil.

## ◆ median()

ValueType median | ( |  | ) | const
| inlineinherited

Return the median value of the current stencil.

## ◆ min()

ValueType min | ( |  | ) | const
| inlineinherited

Return the smallest value in the stencil buffer.

## ◆ moveTo()

void moveTo | ( | const Coord & | ijk | ) |
| inlineinherited

Initialize the stencil buffer with the values of voxel (i, j, k) and its neighbors.

Parameters

  ijk | Index coordinates of stencil center

## ◆ pos()

template<typename GridT, bool IsSafe = true>
template<int i, int j, int k>

unsigned int pos | ( |  | ) | const
| inline

Return linear offset for the specified stencil point relative to its center.

## ◆ setValue()

void setValue | ( | const ValueType & | value | ) |
| inlineinherited

Set the value at the specified location relative to the center of the stencil.

## ◆ size()

int size | ( |  | ) |
| inlineinherited

Return the size of the stencil buffer.
