IsEnabled()

bool FLensDistortionLUT::IsEnabled ( ) const

inline

Returns whether the displacement is enabled.

Member Data Documentation

DistortingDisplacementTexture

FRDGTextureRef FLensDistortionLUT::DistortingDisplacementTexture = nullptr

DistortedViewportUV = UndistortedViewportUV + DistortingDisplacementTexture.Sample(UndistortedViewportUV)

DistortionGridDimensions

FIntPoint FLensDistortionLUT::DistortionGridDimensions = FIntPoint(32, 20)

The distortion warp grid dimensions to use when distorting during the upscale pass

DistortionOverscan

float FLensDistortionLUT::DistortionOverscan = 1.0f

For distortion maps that don't fill the whole frustum, this is the amount of overscan they require but do not fill

kFormat

constexpr EPixelFormat FLensDistortionLUT::kFormat = PF_G32R32F

staticconstexpr

Expected pixel format of the LUT. 16bit floating point do not work when distorting in TSR.

ResolutionFraction

float FLensDistortionLUT::ResolutionFraction = 1.0f

Resolution fraction of the upscaling happening due to distortion.

UndistortingDisplacementTexture

FRDGTextureRef FLensDistortionLUT::UndistortingDisplacementTexture = nullptr

UndistortedViewportUV = DistortedViewportUV + UndistortingDisplacementTexture.BilinearSample(DistortedViewportUV)
