Noise generation

In practice, a scene may contain multiple frames, each task of this scene contains some range of frames to be rendered, consequently each worker may render only a subset of these frames. For the simplification purpose, we assume in this section that a scene has only one frame, so the output image is determined uniquely by the scene.

Noise generation

Let RR denote the rendering process, for each input scene GG, the result of the rendering is an image:

I=R(G)I=R(G)

It is important to note that II is actually never computed, neither by the manager in the noise embedding nor by workers in the frame rendering. The equation above represents only equality.
