Physics-based inverse rendering enables joint optimization of shape, material, and lighting
based on captured 2D images. To ensure accurate reconstruction, using a light model that …

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 …

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 …

Path tracing is now the standard method used to generate realistic imagery in many
domains, eg, film, special effects, architecture etc. Path guiding has recently emerged as a …

With the advent of real-time ray tracing, there is an increasing interest in GPU-friendly
importance sampling techniques. We present such methods to sample convex polygonal …

Path guiding is a promising tool to improve the performance of path tracing algorithms.
However, not much research has investigated what target densities a guiding method …

Focal points are fascinating effects that emerge from various constellations, for example
when light passes through narrow gaps or when objects are seen through lenses or mirrors …

In this paper, we propose a novel and generic family of multiple importance sampling
estimators. We first revisit the celebrated balance heuristic estimator, a widely used Monte …

Previous local guiding methods used 3D data structures to model spatial radiance variations
but struggled with additional dimensions in the path integral, such as temporal changes in …

We present a novel technique to efficiently render complex direct illumination in real‐time. It
is based on a spatio‐temporal randomized mixture model of von Mises‐Fisher (vMF) …
