Classes
class	VdbPrimCIterator
	Iterator over const VDB primitives on a geometry detail. More...
class	VdbPrimIterator
	Iterator over non-const VDB primitives on a geometry detail. More...
class	HoudiniInterrupter
	Wrapper class that adapts a Houdini UT_Interrupt object for use with OpenVDB library routines. More...
class	Interrupter
	Deprecated wrapper class with the same interface as HoudiniInterrupter, however it does not derive from openvdb::util::NullInterrupter. Intended for backwards-compatibility only. More...

	Replace an existing VDB primitive with a new primitive that contains the given grid. More...
OPENVDB_HOUDINI_API bool	evalGridBBox (GridCRef grid, UT_Vector3 corners[8], bool expandHalfVoxel=false)
	Return in corners the corners of the given grid's active voxel bounding box. More...
OPENVDB_HOUDINI_API openvdb::CoordBBox	makeCoordBBox (const UT_BoundingBox &, const openvdb::math::Transform &)
	Construct an index-space CoordBBox from a UT_BoundingBox. More...
template<typename GridTypeListT , typename OpT >
bool	GEOvdbApply (const GEO_PrimVDB &vdb, OpT &op)
	If the given primitive's grid resolves to one of the listed grid types, invoke the functor op on the resolved grid. More...

	Stop forwarding OpenVDB log messages to the Houdini error manager for all operators of the given type. More...
OPENVDB_HOUDINI_API bool	isLogForwarding (OP_OpTypeId)
