## 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...
