Rendering environment lighting using ray tracing is challenging because many rays within the hemisphere are required to be traced. In this work, we propose discrete visibility fields (DVFs), which store visibility information ...

Dusk and dawn scenes have been difficult for brute force path tracers to handle. We identify that a major source of the inefficiency in explicitly path tracing the atmosphere in such conditions stems from wasting samples ...

Multi-fragment rendering provides additional degrees of freedom in postprocessing. It allows us to edit images rendered with antialiasing, motion blur, depth of field, and transparency. To store multiple fragments, ...

Screen-space Ambient Occlusion (AO) is commonly used in games to calculate the exposure of each pixel to ambient lighting with the help of a depth buffer. Due to its screen-space nature, it suffers from several artifacts ...
