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

See Also: DtIndirectEntityGeometry 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 prism 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; DtIndirectEntityGeometry object held by this grid use the same registrar in order to avoid duplication of the unique model data (verts/colors/textures/etc).

using makVrv::DtIndirectGeometryGrid::MapCellIdsToIndirectGeometry = tbb::concurrent_hash_map<Vector3_int, osg::ref_ptr<DtIndirectEntityGeometry>, DtIndirectCellHasher>

The map of a cell 'id' to its corresponding indirect geometry.

using makVrv::DtIndirectGeometryGrid::MapCellIdsToDebugCellDrawables = std::unordered_map<Vector3_int, osg::ref_ptr<osg::Drawable>, DtIndirectCellHasher >

The map of a cell 'id' to its corresponding debug drawable.

using makVrv::DtIndirectGeometryGrid::InstanceTrackingRequestsVector = tbb::concurrent_vector<InstanceTrackingStruct>

Concurrent vector for storing indirect tracking info. As indirect geomtries can be created in multiple threads so can the tracking info Tracking requests are ticked in processInstanceTrackingRequests.
