## Functions

OPENVDB_HOUDINI_API float | computeVoxelSizeFromHoudini (const GU_Detail &detail, const openvdb::Index pointsPerVoxel, const openvdb::math::Mat4d &matrix, const openvdb::Index decimalPlaces, openvdb::util::NullInterrupter &interrupter)
| Compute a voxel size from a Houdini detail.
OPENVDB_HOUDINI_API float | computeVoxelSizeFromHoudini (const GU_Detail &detail, const openvdb::Index pointsPerVoxel, const openvdb::math::Mat4d &matrix, const openvdb::Index decimalPlaces, Interrupter &interrupter)
OPENVDB_HOUDINI_API openvdb::points::PointDataGrid::Ptr | convertHoudiniToPointDataGrid (const GU_Detail &detail, const int compression, const AttributeInfoMap &attributes, const openvdb::math::Transform &transform, const WarnFunc &warnings=[](const std::string &){})
| Convert a Houdini detail into a VDB Points grid.
OPENVDB_HOUDINI_API void | convertPointDataGridToHoudini (GU_Detail &detail, const openvdb::points::PointDataGrid &grid, const std::vector< std::string > &attributes={}, const std::vector< std::string > &includeGroups={}, const std::vector< std::string > &excludeGroups={}, const bool inCoreOnly=false)
| Convert a VDB Points grid into Houdini points and append them to a Houdini Detail.
OPENVDB_HOUDINI_API void | populateMetadataFromHoudini (openvdb::points::PointDataGrid &grid, const GU_Detail &detail, const WarnFunc &warnings=[](const std::string &){})
| Populate VDB Points grid metadata from Houdini detail attributes.
OPENVDB_HOUDINI_API void | convertMetadataToHoudini (GU_Detail &detail, const openvdb::MetaMap &metaMap, const WarnFunc &warnings=[](const std::string &){})
| Convert VDB Points grid metadata into Houdini detail attributes.
OPENVDB_HOUDINI_API int16_t | attributeTupleSize (const GA_Attribute *const attribute)
| Returns supported tuple sizes for conversion from GA_Attribute.
OPENVDB_HOUDINI_API GA_Storage | attributeStorageType (const GA_Attribute *const attribute)
