Class Summary:

Class	Description
`omni::vdb::tool::IVDBTool`	IVDBTool interface.
`omni::vdb::tool::LoadVDBParameters`	Parameter set for loading VDB volumes
`omni::vdb::tool::SaveVDBParameters`	Parameter set for saving VDB volumes

This is an example of how to acquire IVDBTool interface:

static const char s_vdbtool[] = "omni.vdb.tool.plugin";
omni::vdb::tool::IVDBTool* ivdbtool =
    carb::getCachedInterface<omni::vdb::tool::IVDBTool, s_vdbtool>();
if (!ivdbtool)
{
    CARB_LOG_ERROR("Failed to get IVDBTool interface");
    return false;
}

The methods of omni::vdb::tool::IVDBTool are listed below.
