Function Documentation

GenerateLongLatUnwrap() [1/3]

bool CubemapHelpers::GenerateLongLatUnwrap	(	const FTextureResource *	TextureResource,
		const uint32	AxisDimenion,
		const EPixelFormat	SourcePixelFormat,
		TArray64< uint8 > &	BitsOUT,
		FIntPoint &	SizeOUT,
		EPixelFormat &	FormatOUT
	)

Helper function to create an unwrapped 2D image of the cube map ( longitude/latitude ) This version takes explicitly passed properties of the source object, as the sources have different APIs.

Parameters

TextureResource	Source FTextureResource object.
AxisDimenion	axis length of the cube.
SourcePixelFormat	pixel format of the source.
BitsOUT	Raw bits of the 2D image bitmap.
SizeXOUT	Filled with the X dimension of the output bitmap.
SizeYOUT	Filled with the Y dimension of the output bitmap.

Returns

true on success.

Parameters

FormatOUT

Filled with the pixel format of the output bitmap.

	)

Creates an unwrapped 2D image of the cube map ( longitude/latitude )

Parameters

SizeXOUT	Filled with the X dimension of the output bitmap.
SizeYOUT	Filled with the Y dimension of the output bitmap.
FormatOUT	Filled with the pixel format of the output bitmap.

Returns

true on success.

GenerateLongLatUnwrap() [3/3]

ENGINE_API bool CubemapHelpers::GenerateLongLatUnwrap	(	const UTextureRenderTargetCube *	CubeTarget,
		TArray64< uint8 > &	BitsOUT,
		FIntPoint &	SizeOUT,
		EPixelFormat &	FormatOUT
	)

Creates an unwrapped 2D image of the cube map ( longitude/latitude )

Parameters

CubeTarget	Source UTextureRenderTargetCube object.
BitsOUT	Raw bits of the 2D image bitmap.
SizeXOUT	Filled with the X dimension of the output bitmap.
SizeYOUT	Filled with the Y dimension of the output bitmap.
FormatOUT	Filled with the pixel format of the output bitmap.

Returns

true on success.
