Importance Sampling Microfacet-Based BSDFs using the Distribution of Visible Normals
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a new approach to microfacet-based BSDF importance sampling. Previously proposed sampling schemes for popular analytic BSDFs typically begin by choosing a microfacet normal at random in a way that is independent ... -
Interactive Parameter Retrieval for Two-Tone Procedural Textures
(The Eurographics Association and John Wiley and Sons Ltd., 2014)The choice of parameters for procedural textures to achieve a desired appearance poses a challenging problem even for experienced artists. We propose a method to automatically determine such parameters to reproduce the ... -
Layered Reconstruction for Defocus and Motion Blur
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Light field reconstruction algorithms can substantially decrease the noise in stochastically rendered images. Recent algorithms for defocus blur alone are both fast and accurate. However, motion blur is a considerably more ... -
A Physically-Based BSDF for Modeling the Appearance of Paper
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a novel appearance model for paper. Based on our appearance measurements for matte and glossy paper, we find that paper exhibits a combination of subsurface scattering, specular reflection, retroreflection, and ... -

Probabilistic Visibility Evaluation using Geometry Proxies
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Evaluating the visibility between two points is a fundamental problem for ray-tracing and path-tracing algorithms. Ideally, visibility computations are organized such that a minimum number of geometric primitives need to ... -
Semi-Automated Video Morphing
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We explore creating smooth transitions between videos of different scenes. As in traditional image morphing, good spatial correspondence is crucial to prevent ghosting, especially at silhouettes. Video morphing presents ... -
Spectral Ray Differentials
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Light refracted by a dispersive interface leads to beautifully colored patterns that can be rendered faithfully with spectral Monte-Carlo methods. Regrettably, results often suffer from chromatic noise or banding, requiring ... -
User-Assisted Video Stabilization
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a user-assisted video stabilization algorithm that is able to stabilize challenging videos when stateof- the-art automatic algorithms fail to generate a satisfactory result. Current methods do not give the user ... -
Vectorising Bitmaps into Semi-Transparent Gradient Layers
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present an interactive approach for decompositing bitmap drawings and studio photographs into opaque and semi-transparent vector layers. Semi-transparent layers are especially challenging to extract, since they require ...
