Spectral Rendering with the Bounded MESE and sRGB Data
(The Eurographics Association, 2019)
In a recent journal paper, we introduced a technique to represent reflectance spectra by an arbitrary number of Fourier coefficients. As a special case, we converted tristimulus data to three Fourier coefficients. After ...
A Simple Diffuse Fluorescent BBRRDF Model
(The Eurographics Association, 2018)
Fluorescence - the effect of a photon being absorbed at one wavelength and re-emitted at another - is present in many common materials such as clothes and paper. Yet there has been little research in rendering or modeling ...
Clustered Pre-convolved Radiance Caching
(The Eurographics Association, 2014)
We present a scalable method for rendering indirect illumination in diffuse and glossy scenes. Our method builds on pre-convolved radiance caching (RC), which enables reusing the incident radiance computed at a surface ...
Stochastic Soft Shadow Mapping
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
In this paper, we extend the concept of pre-filtered shadow mapping to stochastic rasterization, enabling real-time rendering of soft shadows from planar area lights. Most existing soft shadow mapping methods lose important ...
Physically Meaningful Rendering using Tristimulus Colours
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
In photorealistic image synthesis the radiative transfer equation is often not solved by simulating every wavelength of light, but instead by computing tristimulus transport, for instance using sRGB primaries as a basis. ...
Improving Spectral Upsampling with Fluorescence
(The Eurographics Association, 2020)
Modern photorealistic rendering simulates spectral behaviour of light. Since many assets are still created in different RGB color spaces, spectral upsampling of the RGB colors to a spectral representation is required to ...
