Detailed Description

Manages a bunch of 'cells' for a given cell size (similar to a sparse octree) each cell has a.

See Also

DtIndirectGeometry associated with it if it has at least one entity in it.

DtIndirectGeometryGridNode is the osg::Node derrived object which manages traversal and sets up the indirect geometries for cull/draw Each cell is the same size in world space and is an axis aligned cube (or rectangular prizm if the cell size is not the same for all components) Contains a

DtIndirectModelsContainer object which contains the shared

DtIndirectRegistrar for keeping the unique model information. All

DtIndirectGeometry object held by this grid use the same registrar in order to avoid duplication of the unique model data (verts/colors/textures/etc).

virtual DtIndirectGeometry* makVrv::DtIndirectGeometryGrid::ts_getOrCreateForCell ( const Vector3_int &  cellId, bool &  created  )

virtual

get an indirect geometry for this cell, or create one created parameter indicates whether this was created anew Called by the background update tickables which run in parallel so this function has a mutex in order to be thread safe

virtual bool makVrv::DtIndirectGeometryGrid::ts_removeCell ( const Vector3_int &  cellId )

virtual

remove a cell and indirect geometry for the given cell

virtual Vector3_int makVrv::DtIndirectGeometryGrid::cellIdFor ( const Vector3_64 &  position ) const

virtual

get the cell id for a given position

virtual Vector3_64 makVrv::DtIndirectGeometryGrid::cellCenter ( const Vector3_int &  cellId ) const

virtual

get the cell center of a given cell

virtual

get AABB with padding

virtual DtIndirectModelsContainer* makVrv::DtIndirectGeometryGrid::modelsContainer ( )

virtual

get the internal models' container

virtual void makVrv::DtIndirectGeometryGrid::setCellSize ( const Vector3_64 &  cellSize )

virtual

set/get the cell size

virtual const Vector3_64& makVrv::DtIndirectGeometryGrid::cellSize ( void  ) const

virtual

virtual void makVrv::DtIndirectGeometryGrid::setCellPadding ( const Vector3_64 &  padding )

virtual

set/get the cell padding.

If an entity position is out of a cell (as determined by cellIdFor(), then we can further determine if its still in the old cell expanded with this padding. This is useful for retaining the entity within an old cell, if they flip/flop on the edges of 2 cells (e.g. buoys)

virtual osg::ref_ptr<osg::Node> makVrv::DtIndirectGeometryGrid::gridNode ( )

virtual const MapCellIdsToIndirectGeometry& makVrv::DtIndirectGeometryGrid::mapCellIdsToIndirectGeometry ( void  ) const

virtual

get the map of cell ids to indirect geometries

virtual const MapCellIdsToDebugCellDrawables& makVrv::DtIndirectGeometryGrid::mapCellIdsToDebugCellDrawables ( void  ) const

virtual
