Variables

Name Description

Public variable

float

 

AccumulationGamma

When accumulating apply pow(X,AccumulationGamma), and then apply pow(X,1/AccumulationGamma) on output.

Public variable

TArray64< FImag...

 

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
