Classes
struct	CheckNan< GridT, TreeIterT >
	Checks NaN values. More...
struct	CheckInf< GridT, TreeIterT >
	Checks for infinite values, e.g. 1/0 or -1/0. More...
struct	CheckFinite< GridT, TreeIterT >
	Checks for both NaN and inf values, i.e. any value that is not finite. More...
struct	CheckMagnitude< GridT, TreeIterT >
	Check that the magnitude of a value, a, is close to a fixed magnitude, b, given a fixed tolerance c. That is | |a| - |b| | <= c. More...
struct	CheckRange< GridT, MinInclusive, MaxInclusive, TreeIterT >
	Checks a value against a range. More...
struct	CheckMin< GridT, TreeIterT >
	Checks a value against a minimum. More...
struct	CheckMax< GridT, TreeIterT >
	Checks a value against a maximum. More...
struct	CheckNormGrad< GridT, TreeIterT, GradScheme >
	Checks the norm of the gradient against a range, i.e., |∇Φ| ∈ [min, max]. More...
struct	CheckEikonal< GridT, TreeIterT, StencilT >
	Checks the norm of the gradient at zero-crossing voxels against a range. More...
struct	CheckDivergence< GridT, TreeIterT, DiffScheme >
	Checks the divergence against a range. More...
class	Diagnose< GridT >
	Performs multithreaded diagnostics of a grid. More...
class	CheckLevelSet< GridType >
	Class that performs various types of checks on narrow-band level sets. More...
class	CheckFogVolume< GridType >
	Class that performs various types of checks on fog volumes. More...

Functions
template<class GridType >
std::string	checkLevelSet (const GridType &grid, size_t number=9)
	Perform checks on a grid to see if it is a valid symmetric, narrow-band level set. More...
template<class GridType >
std::string	checkFogVolume (const GridType &grid, size_t number=6)
	Perform checks on a grid to see if it is a valid fog volume. More...
template<class GridType >
bool	uniqueInactiveValues (const GridType &grid, std::vector< typename GridType::ValueType > &values, size_t numValues)
	Threaded method to find unique inactive values. More...
