Perceptually Motivated BRDF Comparison using Single Image
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Surface reflectance of real-world materials is now widely represented by the bidirectional reflectance distribution function (BRDF) and also by spatially varying representations such as SVBRDF and the bidirectional texture ...
FlexyFont: Learning Transferring Rules for Flexible Typeface Synthesis
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Maintaining consistent styles across glyphs is an arduous task in typeface design. In this work we introduce Flexy- Font, a flexible tool for synthesizing a complete typeface that has a consistent style with a given small ...
Statistical Modeling of the 3D Geometry and Topology of Botanical Trees
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
We propose a framework for statistical modeling of the 3D geometry and topology of botanical trees. We treat botanical trees as points in a tree-shape space equipped with a proper metric that captures the geometric and the ...
Self Tuning Texture Optimization
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
The goal of example-based texture synthesis methods is to generate arbitrarily large textures from limited exemplars in order to fit the exact dimensions and resolution required for a specific modeling task. The challenge ...
By-example Synthesis of Curvilinear Structured Patterns
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Many algorithms in Computer Graphics require to synthesize a pattern along a curve. This is for instance the case with line stylization, to decorate objects with elaborate patterns (chains, laces, scratches), or to synthesize ...
CHC+RT: Coherent Hierarchical Culling for Ray Tracing
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
We propose a new technique for in-core and out-of-core GPU ray tracing using a generalization of hierarchical occlusion culling in the style of the CHC++ method. Our method exploits the rasterization pipeline and hardware ...
Mosaic Drawings and Cartograms
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Cartograms visualize quantitative data about a set of regions such as countries or states. There are several different types of cartograms and - for some - algorithms to automatically construct them exist. We focus on ...
Statics Aware Grid Shells
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
We introduce a framework for the generation of polygonal grid-shell architectural structures, whose topology is designed in order to excel in static performances. We start from the analysis of stress on the input surface ...
Generalized Diffusion Curves: An Improved Vector Representation for Smooth-Shaded Images
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
This paper generalizes the well-known Diffusion Curves Images (DCI), which are composed of a set of Bezier curves with colors specified on either side. These colors are diffused as Laplace functions over the image domain, ...
Selective Degree Elevation for Multi-Sided Bézier Patches
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
This paper presents a method to selectively elevate the degree of an S-Patch of arbitrary dimension. We consider not only S-Patches with 2D domains but 3D and higher-dimensional domains as well, of which volumetric cage ...
