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...
