Detailed Description

DtModelInfo is a mapping of a 'model' name to a 'model' id A 'model' can have a number of lods.

An 'lod' has an id

virtual void makVrv::DtModelInfo::setNameAndId ( const std::string &  modelName, int  id  )

virtual

Set up the mapping.

virtual const std::string& makVrv::DtModelInfo::modelName ( void  ) const

virtual

Get the model name.

virtual int makVrv::DtModelInfo::id ( void  ) const

virtual

Get the model id.

virtual const DtLodId& makVrv::DtModelInfo::lodId ( int  lodId ) const

virtual

Get the lod with id equaling lodId.

virtual bool makVrv::DtModelInfo::insertLodEntryAndLod ( int  lodId )

virtual

Insert an lod (implicitly an id) This method is thread safe.

The calls to insertLodEntryAndLod can come from different threads and in any order. The atomic and the map together maintain the mapping of the lod id coming from the call to the actual internal DtLodId whose id is generated using the atomic below. The id of DtLodId and the keys for the map may or may not match. The DtLodIds always start from zero and are monotonically increasing The reason for this is this class is typically used by the Indirect rendering engine/GPU directly, and the bookkeeping needed makes this mandatory
