## 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...
