Detailed Description

template<class GridType>
class openvdb::OPENVDB_VERSION_NAME::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()

Member Function Documentation

template<class GridType>
std::string openvdb::OPENVDB_VERSION_NAME::tools::CheckLevelSet< GridType >::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.
