template<typename DerivedType, typename GridT, bool IsSafe>
const Coord& openvdb::OPENVDB_VERSION_NAME::math::BaseStencil< DerivedType, GridT, IsSafe >::getCenterCoord ( ) const
inline

Return the coordinates of the center point of the stencil.

template<typename DerivedType, typename GridT, bool IsSafe>
const ValueType& openvdb::OPENVDB_VERSION_NAME::math::BaseStencil< DerivedType, GridT, IsSafe >::getCenterValue ( ) const
inline

Return the value at the center of the stencil.

template<typename DerivedType, typename GridT, bool IsSafe>
const ValueType& openvdb::OPENVDB_VERSION_NAME::math::BaseStencil< DerivedType, GridT, IsSafe >::getValue ( unsigned int  pos = 0) const
inline

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.

const GridType& openvdb::OPENVDB_VERSION_NAME::math::BaseStencil< DerivedType, GridT, IsSafe >::grid ( ) const
inline

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

std::bitset<6> openvdb::OPENVDB_VERSION_NAME::math::BaseStencil< DerivedType, GridT, IsSafe >::intersectionMask ( const ValueType isoValue = zeroVal<ValueType>()) const
inline

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().

template<typename DerivedType, typename GridT, bool IsSafe>
void openvdb::OPENVDB_VERSION_NAME::math::BaseStencil< DerivedType, GridT, IsSafe >::moveTo ( const Coord ijk,
const ValueType centerValue 
)
inline

Initialize the stencil buffer with the values of voxel (i, j, k) and its neighbors. The method also takes a value of the center element of the stencil, assuming it is already known.

Parameters
ijkIndex coordinates of stnecil center
centerValueValue of the center element of the stencil

template<typename DerivedType, typename GridT, bool IsSafe>
template<typename IterType >
void openvdb::OPENVDB_VERSION_NAME::math::BaseStencil< DerivedType, GridT, IsSafe >::moveTo ( const IterType iter)
inline

Initialize the stencil buffer with the values of voxel (x, y, z) and its neighbors.

Note
This version is slightly faster than the one above, since the center voxel's value is read directly from the iterator.

template<typename RealType >
void openvdb::OPENVDB_VERSION_NAME::math::BaseStencil< DerivedType, GridT, IsSafe >::moveTo ( const Vec3< RealType > &  xyz)
inline

Initialize the stencil buffer with the values of voxel (x, y, z) and its neighbors.

Parameters
xyzFloating point voxel coordinates of stencil center

This method will check to see if it is necessary to update the stencil based on the cached index coordinates of the center point.
