We implement a novel pattern lighting, that takes arbitrary image as texture and illuminates only from non-white pixels with intensity proportional to pixel value.
Per-Pixel Parallelism
Compared with naive (sub-region) parallelism, our per-pixel parallelism keeps all cores engaged till the last pixel rendered to utilize full computational power.
