Variables

  Type Name Description
Public variable float AccumulationGamma Gamma for accumulation. Typical values are 1.0 and 2.2.
Public variable TArray64< FImageOverlappedPlane > ChannelPlanes  
Public variable int32 NumChannels Number of channels in the tiles. Typical will be 3 (RGB).
Public variable FIntPoint PlaneSize Width and height of each tile in pixels
Public variable TArray64< float >[4] UnpackedDataStorage A temporary buffer that is only initialized to the size of a single sample used during RGBA unpacking.
Public variable TArray64< float > WeightChannelStorage A temporary buffer that is only initialized to the size of a single sample used during weight plane accumulation.
Public variable FImageOverlappedPlane WeightPlane  

Constructors

Functions

  Type Name Description
Public function void

AccumulatePixelData ( const FImagePixelData& InPixelData,
FIntPoint InTileOffset,
FVector2D InSubpixelOffset,
const MoviePipeline::FTileWeight1D& WeightX,
const MoviePipeline::FTileWeight1D& WeightY
)

 Given a rendered tile, accumulate the data to the full size image.
Public function Const void

FetchFinalPixelDataByte ( TArray64< FColor >& OutPixelData
)

 After accumulation is finished, fetch the final image as bytes.
Public function Const void

FetchFinalPixelDataHalfFloat ( TArray64< FFloat16Color >& OutPixelData
)

 After accumulation is finished, fetch the final image as linear colors
Public function Const void

FetchFinalPixelDataLinearColor ( TArray64< FLinearColor >& OutPixelData
)

 After accumulation is finished, fetch the final image as linear colors
Public function Const void

FetchFullImageValue ( float Rgba,
int32 FullX,
int32 FullY
)

 Grab a single pixel from the full res tile and scale it by the appropriate Scale value.
Public function Static FName

GetName ()

  
Public function void

InitMemory ( FIntPoint InPlaneSize,
int32 InNumChannels
)

 Allocates memory.
Public function void

Reset ()

 Resets the PlaneSize and NumChannels but does NOT free the memory because most of the time we're going to just need the same resolution next frame anyways when InitMemory is called again.
Public function void Initializes memory.Resets the memory to 0s so that we can start a new frame.
