makVrv::DtIndirectGeometry Class Reference

 \ ::,

which allows us to hook into our indirect engine to render using indirect rendering. In the case of features, the

See Also
DtIndirectGeometry is parented to the feature tile nodes and manages the indirect rendering of all the feature points in that tile. For paging databases it manages the indirect rendering of a complete tile. For terrain patches it manages the indirect rendering of the full patch. For entities the
DtIndirectGeometry is managed by a
DtIndirectGeometryGrid which has a
DtIndirectGeometry per geo cell. Contains some managers for processing the state (
DtIndirectSwitchManager,
DtIndirectDofManager,
DtIndirectLodManager,
DtIndirectUvOffsetManager,
DtIndirectPerInstanceDataManager) Uses a
DtGpuCulling object for processing the state of the entities and culling them to setup the command buffer for drawing. Finally
DtIndirectDrawComponent objects are used to draw the geometry based on the state

total currently

static void makVrv::DtIndirectGeometry::initializeDtDeKeyedInstances ( DtDe &  de)
static

DtIndirectGeometry has a bunch of components that are references (creators, higher level managers, etc) These are keyed on DtDe and hence call ::instance of those. These implementations are not thread safe. They call findInstance and then registerInstance (if instance was not found) with no higher up locking guarding both functions. When a bunch of DtIndirectGeometries are made from multiple threads, the call to ::instance to any one of these can cause thread safety issues. So, call this function, once from outside (e.g. DtOsgRenderer::postInitialize), so all these are initialized properly and subsequent calls inside ::instance always hit only DtDe.findInstance and return the pointer in question. This was found recently in cdb for a particular database. It's only happenstance that we did not run into this before.
