Cornell Box: direct illumination


In this scene rendered under direct illumination, the rendering integral is only 2-dimensional. At 1 spp, it provides the optimal conditions for Georgiev and Fajardo's BNDS [2016] that outperforms our method. However, as the sample count increases, the blue-noise distribution of BNDS vanish and our method achieves superior results.
