_placeBarriersAndEmulateUavExecution()

virtual void Ogre::CompositorPassClear::_placeBarriersAndEmulateUavExecution ( BoundUav  boundUavs[64], ResourceAccessMap &  uavsAccess, ResourceLayoutMap &  resourcesLayout  )

virtual

Emulates the execution of a UAV to understand memory dependencies, and adds a memory barrier / resource transition if we need to.

Remarks

Note that an UAV->UAV resource transition is just a memory barrier.

Parameters

boundUavs	[in/out] An array of the currently bound UAVs by slot. The derived class CompositorPassUav will write to them as part of the emulation. The base implementation reads from this value.
uavsAccess	[in/out] A map with the last access flag used for each RenderTarget. We need it to identify RaR situations, which are the only ones that don't need a barrier (and also WaW hazards, when explicitly allowed by the pass). Note: We will set the access to ResourceAccess::Undefined to signal other passes that the UAV hazard already has a barrier (just in case there was one already created).
resourcesLayout	[in/out] A map with the current layout of every RenderTarget used so far. Needed to identify if we need to change the resource layout to an UAV.

Reimplemented from Ogre::CompositorPass.
