overridevirtual

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).

Returns a new reference to the texture, which will represent the new mip count when the reallocation is complete. RHIGetAsyncReallocateTexture2DStatus() can be used to check the status of an ongoing or completed reallocation.

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).

Returns: - New reference to the texture, or an invalid reference upon failure

FGraphicsPipelineStateRHIRef FD3D12DynamicRHI::RHICreateGraphicsPipelineState ( const FGraphicsPipelineStateInitializer & Initializer )

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

finaloverridevirtual

Lock a staging buffer to read contents on the CPU that were written by the GPU, without having to stall. @discussion This function requires that you have issued an CopyToStagingBuffer invocation and verified that the FRHIGPUFence has been signaled before calling.

Parameters

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.

Returns: A pointer to the data starting at 'Offset' and of length 'SizeRHI' from 'StagingBuffer', or nullptr when there is an error.

finaloverridevirtual

Implemented by the platform to read directly from the texture. Useful for getting the last back buffer content after a crash. As the RHIReadSurfaceData implementation will copy the texture's content to a new temporary buffer, that won't work for an unknown crash state.
