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...
 
class  InactiveVoxelValues< TreeType >
 
class  InactiveTileValues< TreeType >
