Detailed Description

template<class GridType>
class openvdb::v5_2::tools::CheckLevelSet< GridType >

Class that performs various types of checks on narrow-band level sets.

Note
The most common usage is to simply call CheckLevelSet::check()

inline

Member Function Documentation

std::string check ( size_t  n = 9,
bool  updateMask = false 
)
inline

Return a nonempty message if an error or issue is detected. Only runs tests with a number lower than or equal to n, where:

Fast checks 1: value type is floating point 2: has level set class type 3: has uniform scale 4: background value is positive and n*dx

Slower checks 5: no active tiles 6: all the values are finite, i.e not NaN or infinite 7: active values in range between +-background 8: abs of inactive values = background, i.e. assuming a symmetric narrow band!

Relatively slow check (however multi-threaded) 9: norm of gradient at zero-crossings is one, i.e. satisfied the Eikonal equation.

std::string checkBackground ( Real  halfWidth = LEVEL_SET_HALF_WIDTH) const
inline

Return a nonempty message if the background value is larger than or equal to the halfWidth*voxelSize.

Note
Small run-time overhead
std::string checkClassType ( ) const
inline

Return message if the grid's class is a level set.

Note
Small run-time overhead
std::string checkEikonal ( bool  updateMask = false,
ValueType  minV = 0.5,
ValueType  maxV = 1.5 
)
inline

Return a nonempty message if the norm of the gradient of the active voxels is out of the range minV to maxV.

Note
Significant run-time overhead
std::string checkFinite ( bool  updateMask = false)
inline

Return a nonempty message if any of the values are not finite. i.e. NaN or inf.

Note
Medium run-time overhead
std::string checkInactiveValues ( bool  updateMask = false)
inline

Return a nonempty message if the the inactive values do not have a magnitude equal to the background value.

Note
Medium run-time overhead
std::string checkRange ( bool  updateMask = false)
inline

Return a nonempty message if the active voxel values are out-of-range.

Note
Medium run-time overhead
std::string checkTiles ( ) const
inline

Return a nonempty message if the grid has no active tile values.

Note
Medium run-time overhead
std::string checkTransform ( ) const
inline

Return a nonempty message if the grid's transform does not have uniform scaling.

Note
Small run-time overhead
static std::string checkValueType ( )
inlinestatic

Return a nonempty message if the grid's value type is a floating point.

Note
No run-time overhead
void clear ( )
inline

Clear the mask and error counter.

Index64 failureCount ( ) const
inline

Return total number of failed checks.

Note
If only one check was performed and the mask was updated failureCount equals valueCount.
const GridType& grid ( ) const
inline

Return a const reference to the grid.

MaskType::ConstPtr mask ( ) const
inline

Return a boolean mask of all the values (i.e. tiles and/or voxels) that have failed one or more checks.

MaskType::Ptr mask ( )
inline

Return a boolean mask of all the values (i.e. tiles and/or voxels) that have failed one or more checks.

Index64 valueCount ( ) const
inline

Return the number of values (i.e. background, tiles or voxels) that have failed one or more checks.
