Detailed Description

template<class GridType>
class openvdb::v12_0::tools::CheckFogVolume< GridType >

Class that performs various types of checks on fog volumes.

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

Constructor & Destructor Documentation

CheckFogVolume ( const GridType &  grid)
inline

Member Function Documentation

std::string check ( size_t  n = 6,
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 FOG volume class type 3: background value is zero

Slower checks 4: all the values are finite, i.e not NaN or infinite 5: inactive values are zero 6: active values are in the range [0,1]

std::string checkBackground ( ) const
inline

Return a nonempty message if the background value is not zero.

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

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

Note
Small 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 any of the inactive values are not zero.

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, i.e. not in the range [0,1].

Note
Medium 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.
