StagingBuffer	The buffer to lock.
Fence	An optional fence synchronized with the last buffer update.
Offset	The offset in the buffer to return.
SizeRHI	The length of the region in the buffer to lock.

finaloverridevirtual

Starts an asynchronous texture reallocation. It may complete immediately if the reallocation could be performed without any reshuffling of texture memory, or if there isn't enough memory. The specified status counter will be decremented by 1 when the reallocation is complete (success or failure).

Parameters

Texture2D	- Texture to reallocate
NewMipCount	- New number of mip-levels
NewSizeX	- New width, in pixels
NewSizeY	- New height, in pixels
RequestStatus	- Will be decremented by 1 when the reallocation is complete (success or failure).

(Y,Z,W) of Values is ignored. Typed floating point buffers undergo standard format conversion during the write operation. The conversion is determined by the format of the UAV.

Parameters

Values	The values to clear the UAV to, one component per channel (XYZW = RGBA). Channels not supported by the UAV are ignored.

Implements IRHIComputeContext.

(Y,Z,W) of Values is ignored. Typed integer buffers undergo standard format conversion during the write operation. The conversion is determined by the format of the UAV.

Parameters

UnorderedAccessViewRHI	The UAV to clear.

virtual FGraphicsPipelineStateRHIRef FOpenGLDynamicRHI::RHICreateGraphicsPipelineState ( const FGraphicsPipelineStateInitializer & Initializer )

inlineoverridevirtual

Creates a graphics pipeline state object (PSO) that represents a complete gpu pipeline for rendering. This function should be considered expensive to call at runtime and may cause hitches as pipelines are compiled.

Parameters

Initializer - Descriptor object defining all the information needed to create the PSO, as well as behavior hints to the RHI.

Returns: FGraphicsPipelineStateRHIRef that can be bound for rendering; nullptr if the compilation fails. CAUTION: On certain RHI implementations (eg, ones that do not support runtime compilation) a compilation failure is a Fatal error and this function will not return. CAUTION: Even though this is marked as threadsafe, it is only valid to call from the render thread or the RHI thread. It need not be threadsafe unless the RHI support parallel translation. CAUTION: Platforms that support RHIThread but don't actually have a threadsafe implementation must flush internally with FScopedRHIThreadStaller StallRHIThread(FRHICommandListExecutor::GetImmediateCommandList()); when the call is from the render thread
