Cycles: light spread importance sampling for rectangular area lights Compute a subset of the area light that actually affects the shading point and only samples points within that. It's not perfect as the real subset is a circle instead of a rectangle, and the attenuation is not accounted for. However it massively reduces noise for shading points near the area light anyway. Ellipse shaped area lights do not have this importance sampling, but do not have solid angle importance sampling either. Ref D10594 |
