Rendering Artistic Light Patterns
(The Eurographics Association, 2015)
By combining knowledge from computer graphics and visual arts, we have built a projection installation based on a novel sketch-based shape pattern rendering method. Our novel rendering method is guided by an artist's ...
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. ...
Statistical Characterization of Surface Reflectance
(The Eurographics Association, 2014)
The classification of surface reflectance functions as diffuse, specular, and glossy has been introduced by Heckbert more than two decades ago. Many rendering algorithms are dependent on such a classification, as different ...
Linear Transport Theory and Applications to Rendering
(The Eurographics Association, 2014)
In this talk, I will give an overview of one-dimensional Linear Transport Theory, which concerns itself with the study of random scattering and absorption processes and the inference of large-scale behavior from simple ...
ISHair: Importance Sampling for Hair Scattering
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
We present an importance sampling method for the bidirectional scattering distribution function (bsdf) of hair. Our method is based on the multi-lobe hair scattering model presented by Sadeghi et al. [SPJT10]. We reduce ...
Example-Based Fractured Appearance
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
A common weathering effect is the appearance of cracks due to material fractures. Previous exemplar-based aging and weathering methods have either reused images or sought to replicate observed patterns exactly. We introduce ...
Approximating Functions on a Mesh with Restricted Voronoï Diagrams
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
We propose a method that computes a piecewise constant approximation of a function defined on a mesh. The approximation is associated with the cells of a restricted Voronoï diagram. Our method optimizes an objective function ...
The Material Definition Language
(The Eurographics Association, 2015)
We introduce the physically-based Material Definition Language (MDL). Based on the principle of strictly separating material definition and rendering algorithms, each MDL material is applicable across different rendering ...
Photon Splatting Using a View-Sample Cluster Hierarchy
(The Eurographics Association, 2016)
Splatting photons onto primary view samples, rather than gathering from a photon acceleration structure, can be a more efficient approach to evaluating the photon-density estimate in interactive applications, where the ...
High-Performance Rendering of Realistic Cumulus Clouds Using Pre-computed Lighting
(The Eurographics Association, 2014)
We present a new method for rendering realistic cumulus clouds in real time. The clouds in our approach consist of randomly rotated and scaled copies of a single reference particle. During the pre-processing, we pre-compute ...
