Detailed Description

template<typename GridT, typename InterruptT = util::NullInterrupter>
class openvdb::v9_0::tools::LevelSetSphere< GridT, InterruptT >

Generates a signed distance field (or narrow band level set) to a single sphere.

Note

The leapfrog algorithm employed in this class is best suited for a single large sphere. For multiple small spheres consider using the faster algorithm in tools/ParticlesToLevelSet.h

Constructor & Destructor Documentation

LevelSetSphere ( ValueT  radius, const Vec3T &  center, InterruptT *  interrupt = nullptr  )

inline

Constructor.

Parameters

radius	radius of the sphere in world units
center	center of the sphere in world units
interrupt	pointer to optional interrupter. Use template argument util::NullInterrupter if no interruption is desired.

Note

If the radius of the sphere is smaller than 1.5*voxelSize, i.e. the sphere is smaller than the Nyquist frequency of the grid, it is ignored!

Member Function Documentation

GridT::Ptr getLevelSet ( ValueT  voxelSize, ValueT  halfWidth, bool  threaded = true  )

inline

Returns

a narrow-band level set of the sphere

Parameters

voxelSize	Size of voxels in world units
halfWidth	Half-width of narrow-band in voxel units
threaded	If true multi-threading is enabled (true by default)
