Function Documentation

template<typename PointIndexTreeType , typename PointArrayType >
void GUvdbConvertIndexToOffset ( PointIndexTreeType &  tree,
const PointArrayType &  points 
)
inline

Utility method to change point indices into Houdini geometry offsets.

Note
PointIndexGrid's that store Houdini geometry offsets are not safe to write to disk, offsets are not guaranteed to be immutable under defragmentation operations or I/O.

Definition at line 323 of file GU_VDBPointTools.h.

template<typename ParticleArrayType >
openvdb::tools::ParticleIndexAtlas::Ptr GUvdbCreateParticleAtlas ( const double  minVoxelSize,
const ParticleArrayType &  particles 
)
inline

Utility method to construct a ParticleAtals.

The ParticleAtals supports fast spatial queries for particles.

Definition at line 357 of file GU_VDBPointTools.h.

openvdb::tools::PointIndexGrid::Ptr GUvdbCreatePointIndexGrid ( const openvdb::math::Transform &  xform,
const GU_Detail detail,
const GA_PointGroup pointGroup = nullptr 
)
inline

Utility method to construct a PointIndexGrid.

The PointIndexGrid supports fast spatial queries for points.

Definition at line 333 of file GU_VDBPointTools.h.

template<typename PointArrayType >
openvdb::tools::PointIndexGrid::Ptr GUvdbCreatePointIndexGrid ( const openvdb::math::Transform &  xform,
const PointArrayType &  points 
)
inline

Utility method to construct a PointIndexGrid.

The PointIndexGrid supports fast spatial queries for points.

Definition at line 347 of file GU_VDBPointTools.h.

GU_VDBPointList<openvdb::Vec3s>::Ptr GUvdbCreatePointList ( const GU_Detail detail,
const GA_PointGroup pointGroup = nullptr 
)
inline

Utility method to construct a GU_VDBPointList.

The GU_VDBPointList is compatible with the PointIndexGrid and ParticleAtals structures.

Definition at line 311 of file GU_VDBPointTools.h.

openvdb::MaskGrid::Ptr GUvdbCreatePointMaskGrid ( const openvdb::math::Transform &  xform,
const GU_Detail detail,
const GA_PointGroup pointGroup = nullptr 
)
inline

Utility method to construct a boolean PointMaskGrid.

This method supports packed points.

Definition at line 373 of file GU_VDBPointTools.h.

openvdb::tools::PointIndexGrid::Ptr GUvdbCreatePointOffsetGrid ( const openvdb::math::Transform &  xform,
const GU_Detail detail,
const GA_PointGroup pointGroup = nullptr 
)
inline

Utility method to construct a PointIndexGrid that stores Houdini geometry offsets.

Note
PointIndexGrid's that store Houdini geometry offsets are not safe to write to disk, offsets are not guaranteed to be immutable under defragmentation operations or I/O.
