Detailed Description

template<typename GridT, typename TreeIterT = typename GridT::ValueOnCIter, math::BiasedGradientScheme GradScheme = math::FIRST_BIAS>
struct openvdb::v9_0::tools::CheckNormGrad< GridT, TreeIterT, GradScheme >

Checks the norm of the gradient against a range, i.e., |∇Φ| ∈ [min, max].

Note

Internally the test is performed as |∇Φ|² ∈ [min², max²] for optimization reasons.

Constructor & Destructor Documentation

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

inline

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

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 voxel location of the iterator is out of range.

std::string str ( ) const

inline

Return a string describing a failed check.
