Analytic Tangent Irradiance Environment Maps for Anisotropic Surfaces
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
Environment-mapped rendering of Lambertian isotropic surfaces is common, and a popular technique is to use a quadratic spherical harmonic expansion. This compact irradiance map representation is widely adopted in interactive ...
Perlin Noise Pixel Shaders
(The Eurographics Association, 2001)
While working on a method for supporting real-time procedural solid texturing, we developed a general purpose multipass pixel shader to generate the Perlin noise function. We implemented this algorithm on SGI workstations ...
Image-based Remapping of Material Appearance
(The Eurographics Association, 2017)
Digital 3D content creation requires the ability to exchange assets across multiple software applications. For many 3D asset types, standard formats and interchange conventions are available. For material definitions, ...
Algorithms for Division Free Perspective Correct Rendering
(The Eurographics Association, 2000)
Well known implementations for perspective correct rendering of planar polygons require a division per rendered pixel. Such a division is better to be avoided as it is an expensive operation in terms of silicon gates and ...
A Quadrilateral Rendering Primitive
(The Eurographics Association, 2004)
The only surface primitives that are supported by common graphics hardware are triangles and more complex shapes have to be triangulated before being sent to the rasterizer. Even quadrilaterals, which are frequently used ...
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 ...
Extracting Microfacet-based BRDF Parameters from Arbitrary Materials with Power Iterations
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
We introduce a novel fitting procedure that takes as input an arbitrary material, possibly anisotropic, and automatically converts it to a microfacet BRDF. Our algorithm is based on the property that the distribution of ...
Unifying Color and Texture Transfer for Predictive Appearance Manipulation
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Recent color transfer methods use local information to learn the transformation from a source to an exemplar image, and then transfer this appearance change to a target image. These solutions achieve very successful results ...
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 ...
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 ...
