Detailed Description

template<typename GridT, typename InterruptT = util::NullInterrupter>
class openvdb::v13_0::tools::LevelSetMorphing< GridT, InterruptT >

Shape morphology of level sets. Morphing from a source narrow-band level sets to a target narrow-band level set.

The InterruptType template argument below refers to any class with the following interface:

class Interrupter {
  ...
public:
  void start(const char* name = nullptr) // called when computations begin
  void end()                             // called when computations end
  bool wasInterrupted(int percent=-1)    // return true to break computation
};

Note

If no template argument is provided for this InterruptType, the util::NullInterrupter is used, which implies that all interrupter calls are no-ops (i.e., they incur no computational overhead).

Member Function Documentation

size_t advect ( ValueType  time0, ValueType  time1  )

inline

Advect the level set from its current time, time0, to its final time, time1. If time0 > time1, perform backward advection.

Returns

the number of CFL iterations used to advect from time0 to time1

int getGrainSize ( ) const

inline

Return the grain size used for multithreading.

int getNormCount ( ) const

inline

Return the number of normalizations performed per track or normalize call.

math::BiasedGradientScheme getSpatialScheme ( ) const

inline

Return the spatial finite-difference scheme.

math::TemporalIntegrationScheme getTemporalScheme ( ) const

inline

Return the temporal integration scheme.

math::BiasedGradientScheme getTrackerSpatialScheme ( ) const

inline

Return the spatial finite-difference scheme.

math::TemporalIntegrationScheme getTrackerTemporalScheme ( ) const

inline

Return the temporal integration scheme.

void invertMask ( bool  invert = true )

inline

Invert the optional mask, i.e. min->max in the original mask maps to 1->0 in the inverted alpha mask.

bool isMaskInverted ( ) const

inline

Return true if the mask is inverted, i.e. min->max in the original mask maps to 1->0 in the inverted alpha mask.

ValueType maxMask ( ) const

inline

Return the maximum value of the mask to be used for the derivation of a smooth alpha value.

ValueType minMask ( ) const

inline

Return the minimum value of the mask to be used for the derivation of a smooth alpha value.

void setAlphaMask ( const GridT &  maskGrid )

inline

Define the alpha mask.

void setGrainSize ( int  grainsize )

inline

Set the grain size used for multithreading.

Note

A grain size of 0 or less disables multithreading!

void setMaskRange ( ValueType  min, ValueType  max  )

inline

Define the range for the (optional) scalar mask.

Parameters

min	Minimum value of the range.
max	Maximum value of the range.

Mask values outside the range maps to alpha values of respectfully zero and one, and values inside the range maps smoothly to 0->1 (unless of course the mask is inverted).

Exceptions

ValueError

if min is not smaller than max.

void setNormCount ( int  n )

inline

Set the number of normalizations performed per track or normalize call.

void setSpatialScheme ( math::BiasedGradientScheme  scheme )

inline

Set the spatial finite-difference scheme.

void setTarget ( const GridT &  targetGrid )

inline

Redefine the target level set.

void setTemporalScheme ( math::TemporalIntegrationScheme  scheme )

inline

Set the temporal integration scheme.

void setTrackerSpatialScheme ( math::BiasedGradientScheme  scheme )

inline

Set the spatial finite-difference scheme.

void setTrackerTemporalScheme ( math::TemporalIntegrationScheme  scheme )

inline

Set the temporal integration scheme.
