Gamut Mapping Spatially Varying Reflectance with an Improved BRDF Similarity Metric
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
Recent spatially varying reflectance (svBRDF) printing systems can reproduce an input document as a combination of matte, glossy and metallic inks. Due to the limited number of inks, this reproduction process incurs some ...

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 ...
Matting and Compositing for Fresnel Reflection on Wavy Surfaces
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
This paper introduces a framework that can extract an alpha matte from a single image with Fresnel reflection, and that can composite other objects with the image such that plausible reflections are included. Our method ...
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 ...
Geometry Presorting for Implicit Object Space Partitioning
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
We present a new data structure for object space partitioning that can be represented completely implicitly. The bounds of each node in the tree structure are recreated at run-time from the scene objects contained therein. ...
Artistic Illumination Transfer for Portraits
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
Relighting a portrait in a single image is still a challenging problem, particularly when only a single artistic reference photograph or painting is provided. In this paper, we propose an artistic illumination transfer ...
Intrinsic Images by Clustering
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
Decomposing an input image into its intrinsic shading and reflectance components is a long-standing ill-posed problem. We present a novel algorithm that requires no user strokes and works on a single image. Based on simple ...
Progressive Virtual Beam Lights
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
A recent technique that forms virtual ray lights (VRLs) from path segments in media, reduces the artifacts common to VPL approaches in participating media, however, distracting singularities still remain. We present Virtual ...
