We propose a set of techniques to efficiently importance sample the derivatives of a wide
range of Bidirectional Reflectance Distribution Function (BRDF) models. In differentiable …

Importance sampling using a light tree (ie, a hierarchy of light clusters) has been widely
used for many-light rendering. This technique samples a light source by stochastically …

Sampling according to a visible normal distribution function (VNDF) is often used to sample
rays scattered by glossy surfaces, such as the Smith-GGX microfacet model. However, for …

A content management system may maintain a description that represents a 3D virtual
environment and a publish/subscribe model in which clients subscribe to con tent items that …

We propose a taxonomy and terminology for rendering engineers to use in describing the
main categories of mathematical lobes that are combined to implement bidirectional …

A content management system may maintain a scene description that represents a 3D
virtual environment and a publish/subscribe model in which clients subscribe to content …

In this paper we explore the intricate relationship between volumetric albedo and
attenuation. When rendering realistic skin and complex FX elements, the traditional …

In der Computergrafik stellt die realistische Darstellung von Vegetation eine besondere
Herausforderung dar. Die enorme Vielzahl an existierenden Pflanzen und Gewächsen …

For almost its entire existence my hobby renderer, Takua Renderer, has built and run on
Mac, Windows, and Linux on x86-64. I maintain Takua on all three major desktop operating …
