Free-space diffractions are an optical phenomenon where light appears to "bend" around the geometric edges and corners of scene objects. In this paper we present an efficient method to simulate such effects. We derive an edge-based formulation of …
We propose new methods for combining NDFs in microfacet theory, enabling a wider range of surface statistics. The new BSDFs that follow allow for independent adjustment of appearance at grazing angles, and can't be represented by linear blends of …
The continuous advancement of photorealism in rendering is accompanied by a growth in texture data and, consequently, increasing storage and memory demands. To address this issue, we propose a novel neural compression technique specifically designed …
We consider the problem of multiple scattering on Smith microfacets. This problem is equivalent to computing volumetric light transport in a homogeneous slab. Although the symmetry of the slab allows for significant simplification, fully analytic …
Real-time graphics is on the cusp of a historic transition to path tracing. With recent advances in hardware ray tracing, systems research, stochastic light sampling, and denoising, we show that complex light transport effects can be path traced in …
We introduce a general framework for transforming biased estimators into unbiased and consistent estimators for the same quantity. We show how several existing unbiased and consistent estimation strategies in rendering are special cases of this …
Real-time graphics is on the cusp of a historic transition to path tracing, one of the largest breakthroughs for real-time graphics in many years. Path tracing is the most accurate way of rendering but is also computationally intensive due to the …
