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 ...
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 ...
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 ...
Line-Sweep Ambient Obscurance
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Screen-space ambient occlusion and obscurance have become established methods for rendering global illumi- nation effects in real-time applications. While they have seen a steady line of refinements, their computational ...
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 ...
Layered Reflective Shadow Maps for Voxel-based Indirect Illumination
(The Eurographics Association, 2014)
We introduce a novel voxel-based algorithm that interactively simulates both diffuse and glossy single-bounce indirect illumination. Our algorithm generates high quality images similar to the reference solution while using ...
Filtering Distributions of Normals for Shading Antialiasing
(The Eurographics Association, 2016)
High-frequency illumination effects, such as highly glossy highlights on curved surfaces, are challenging to render in a stable manner. Such features can be much smaller than the area of a pixel and carry a high amount of ...
Interactive Position-dependent Customization of Transfer Function Classification Parameters in Volume Rendering
(The Eurographics Association, 2015)
In direct volume rendering (DVR) and related techniques a basic operation is the classification of data values by mapping (mostly scalar) intensities to color values using a transfer function. However, in some cases this ...
