Efficiently rendering direct lighting from millions of dynamic light sources using Monte Carlo
integration remains a challenging problem, even for off-line rendering systems. We …

Even with the advent of hardware‐accelerated ray tracing in modern GPUs, only a small
number of rays can be traced at each pixel in real‐time applications. This presents a …

As scenes become ever more complex and real-time applications embrace ray tracing, path
sampling algorithms that maximize quality at low sample counts become vital. Recent …

Multiple importance sampling (MIS) is a provably good way to combine a finite set of
sampling techniques to reduce variance in Monte Carlo integral estimation. However, there …

It has been shown that rendering in the gradient domain, ie, estimating finite difference
gradients of image intensity using correlated samples, and combining them with direct …

To render higher quality images from the samples generated by path tracing with a low
sample count, we propose a novel path reuse approach that processes a fixed collection of …

Recent advancements in spatiotemporal reservoir resampling (ReSTIR) leverage sample
reuse from neighbors to efficiently evaluate the path integral. Like rasterization, ReSTIR …

Caustics are complex optical effects caused by the light being concentrated in a small area
due to reflection or refraction on surfaces with low roughness, typically under a sharp light …

Image-space denoising techniques have been widely employed in Monte Carlo rendering,
