Variables

  Type Name Description
Public variable float AccumulationGamma When accumulating apply pow(X,AccumulationGamma), and then apply pow(X,1/AccumulationGamma) on output.
Public variable TArray64< FImageTilePlane > ImagePlanes Actual pixel data.
Public variable float KernelRadius Radius of the kernel, in units of the final image. A value of 1.0 means a radius of one pixel.
Public variable int32 NumChannels Number of channels in the tiles. Typical will be 3 (RGB).
Public variable int32 NumTilesX Horizontal tiles.
Public variable int32 NumTilesY Vertical tiles.
Public variable int32 TileSizeX Width of each tile in pixels
Public variable int32 TileSizeY Height of each tile in pixels
