Detailed Description

template<typename GridT, typename TreeIterT = typename GridT::ValueOnCIter, typename StencilT = math::WenoStencil<GridT>>
struct openvdb::v9_0::tools::CheckEikonal< GridT, TreeIterT, StencilT >

Checks the norm of the gradient at zero-crossing voxels against a range.

CheckEikonal differs from CheckNormGrad in that it only checks the norm of the gradient at voxel locations where the FD-stencil crosses the zero isosurface!

Constructor & Destructor Documentation

CheckEikonal ( const GridT &  grid, const ValueType &  _min, const ValueType &  _max  )

inline

Constructor taking a grid and a range to be tested against.

CheckEikonal ( const CheckEikonal< GridT, TreeIterT, StencilT > &  other )

inline

Member Function Documentation

bool operator() ( const ValueType &  v ) const

inline

Return true if the value is smaller than min or larger than max.

bool operator() ( const TreeIterT &  ) const

inline

Return true if zero is outside the range.

Note

We assume that the norm of the gradient of a tile is always zero.

bool operator() ( const VoxelIterT &  iter ) const

inline

Return true if the norm of the gradient at a zero-crossing voxel location of the iterator is out of range.

std::string str ( ) const

inline

Return a string describing a failed check.
