This paper is focused on the Bidirectional Reflectance Distribution Function (BRDF) in the
context of algorithms for computational production of realistic synthetic images. We provide a …

Photorealistic rendering of real world environments is important in a range of different areas;
including Visual Special effects, Interior/Exterior Modelling, Architectural Modelling, Cultural …

Computer graphics systems are capable of generating stunningly realistic images of objects
that have never physically existed. In order for computers to create these accurately detailed …

We present a new technique for importance sampling products of complex functions using
wavelets. First, we generalize previous work on wavelet products to higher dimensional …

In this paper we present the first practical method for importance sampling functions
represented as spherical harmonics (SH). Given a spherical probability density function …

We propose an analysis of numerical integration based on sampling theory, whereby the
integration error caused by aliasing is suppressed by pre‐filtering. We derive a pre‐filter for …

Specular microfacet distributions have been successfully employed by many authors for
representing glossiness of materials. They are generally combined with a Lambertian term …

As image-based surface reflectance and illumination gain wider use in physically-based
rendering systems, it is becoming more critical to provide representations that allow …

Hand in hand with the rapid development of machine learning, deep learning and
generative AI algorithms and architectures, the graphics community has seen a remarkable …

Acquired data often provides the best knowledge of a material's bidirectional reflectance
distribution function (BRDF). Its integration into most real-time rendering systems requires …
