Detailed Description

FTextureResource implementation for streamable 2D textures.

Constructor & Destructor Documentation

◆ FTexture2DResource()

FTexture2DResource::FTexture2DResource	(	UTexture2D *	InOwner,
		const FStreamableRenderResourceState &	InState
	)

Minimal initialization constructor.

Parameters

InOwner	UTexture2D which this FTexture2DResource represents.
InPostInitState	The renderthread coherent state the resource will have once InitRHI() will be called.

Minimal initialization constructor.

Parameters

InOwner	UTexture2D which this FTexture2DResource represents.
InState

◆ ~FTexture2DResource()

FTexture2DResource::~FTexture2DResource ( )

virtual

Destructor, freeing MipData in the case of resource being destroyed without ever having been initialized by the rendering thread via InitRHI.

Member Function Documentation

◆ CacheSamplerStateInitializer()

void FTexture2DResource::CacheSamplerStateInitializer ( const UTexture2D * InOwner )

Set the value of Filter, AddressU, AddressV, AddressW and MipBias from FStreamableTextureResource on the gamethread.

◆ CalculateTightPackedMipSize()

uint32 FTexture2DResource::CalculateTightPackedMipSize	(	int32	SizeX,
		int32	SizeY,
		EPixelFormat	PixelFormat,
		uint32 &	OutPitch
	)

static

◆ GetPlatformMipsSize()

uint64 FTexture2DResource::GetPlatformMipsSize ( uint32 NumMips ) const

overridevirtual

Returns the platform mip size for the given mip count.

Implements FStreamableTextureResource.

◆ GetTexture2DResource() [1/2]

virtual FTexture2DResource * FTexture2DResource::GetTexture2DResource ( )

inlinevirtual

Reimplemented from FTextureResource.

◆ GetTexture2DResource() [2/2]

virtual const FTexture2DResource * FTexture2DResource::GetTexture2DResource ( ) const

inlinevirtual

Reimplemented from FTextureResource.

◆ InitRHI()

void FTexture2DResource::InitRHI ( FRHICommandListBase & RHICmdList )

overridevirtual

Initializes the RHI resources used by this resource. Called when entering the state where both the resource and the RHI have been initialized. This is only called by the rendering thread.

Reimplemented from FStreamableTextureResource.

◆ IsProxy()

virtual bool FTexture2DResource::IsProxy ( ) const

inlineoverridevirtual

Returns true if the resource is proxying another one.

Reimplemented from FTextureResource.

◆ WarnRequiresTightPackedMip()

void FTexture2DResource::WarnRequiresTightPackedMip	(	int32	SizeX,
		int32	SizeY,
		EPixelFormat	PixelFormat,
		uint32	Pitch
	)

static
