SizeY	- height of the texture to create
Format	- EPixelFormat texture format
NumMips	- number of mips to generate or 0 for full mip pyramid
Flags	- ETextureCreateFlags creation flags

inlinefinaloverridevirtual

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. RHIFinalizeAsyncReallocateTexture2D() must be called to complete the 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

	)

inlinefinaloverridevirtual

Updates a region of a 2D texture from system memory

Parameters

Texture	- the RHI texture resource to update
MipIndex	- mip level index to be modified
UpdateRegion	- The rectangle to copy source image data from
SourcePitch	- size in bytes of each row of the source image
SourceData	- source image data, starting at the upper left corner of the source rectangle (in same pixel format as texture)

Implements FDynamicRHI.

		uint32	SourceRowPitch,
		uint32	SourceDepthPitch,
		const uint8 *	SourceData
	)

inlinefinaloverridevirtual

Updates a region of a 3D texture from system memory

Parameters

Texture	- the RHI texture resource to update
MipIndex	- mip level index to be modified
UpdateRegion	- The rectangle to copy source image data from
SourceRowPitch	- size in bytes of each row of the source image, usually Bpp * SizeX
SourceDepthPitch	- size in bytes of each depth slice of the source image, usually Bpp * SizeX * SizeY
SourceData	- source image data, starting at the upper left corner of the source rectangle (in same pixel format as texture)

Implements FDynamicRHI.

		const void *	Contents
	)

inlinefinaloverridevirtual

Implements FDynamicRHI.

◆ Shutdown()

void FNullDynamicRHI::Shutdown ( )

virtual

Shutdown the RHI; handle shutdown and resource destruction before the RHI's actual destructor is called (so that all resources of the RHI are still available for shutdown).

Implements FDynamicRHI.
