Optimizing BRDF Orientations for the Manipulation of Anisotropic Highlights
(The Eurographics Association and John Wiley and Sons Ltd., 2014)This paper introduces a system for the direct editing of highlights produced by anisotropic BRDFs, which we call anisotropic highlights. We first provide a comprehensive analysis of the link between the direction of ... -
Parameter Estimation and Comparative Evaluation of Crowd Simulations
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a novel framework to evaluate multi-agent crowd simulation algorithms based on real-world observations of crowd movements. A key aspect of our approach is to enable fair comparisons by automatically estimating ... -
Pose Partitioning for Multi-resolution Segmentation of Arbitrary Mesh Animations
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a complete approach to efficiently deriving a varying level-of-detail segmentation of arbitrary animated objects. An over-segmentation is built by combining sets of initial segments computed for each input pose, ... -
Rate-distortion Optimized Compression of Motion Capture Data
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Lossy compression of motion capture data can alleviate the problems of efficient storage and transmission by exploiting the redundancy and the superfluous precision of the data. When considering the acceptable amount of ... -
Interactive Motion Mapping for Real-time Character Control
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Abstract It is now possible to capture the 3D motion of the human body on consumer hardware and to puppet in real time skeleton-based virtual characters. However, many characters do not have humanoid skeletons. Characters ... -
Crack-free Rendering of Dynamically Tesselated B-Rep Models
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We propose a versatile pipeline to render B-Rep models interactively, precisely and without rendering-related artifacts such as cracks. Our rendering method is based on dynamic surface evaluation using both tesselation and ... -
IISPH-FLIP for Incompressible Fluids
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We propose to use Implicit Incompressible Smoothed Particle Hydrodynamics (IISPH) for pressure projection and boundary handling in Fluid-Implicit-Particle (FLIP) solvers for the simulation of incompressible fluids. This ... -
On-line Real-time Physics-based Predictive Motion Control with Balance Recovery
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In this paper, we present an on-line real-time physics-based approach to motion control with contact repositioning based on a low-dimensional dynamics model using example motion data. Our approach first generates a reference ... -
Feedback Control for Rotational Movements in Feature Space
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Synthesizing controllers for rotational movements in feature space is an open research problem and is particularly challenging because of the need to precisely regulate the character s global orientation, angular momentum ... -
Efficient Enforcement of Hard Articulation Constraints in the Presence of Closed Loops and Contacts
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In rigid body simulation, one must distinguish between contacts (so-called unilateral constraints) and articulations (bilateral constraints). For contacts and friction, iterative solution methods have proven most useful ... -
Laplacian Colormaps: a Framework for Structure-preserving Color Transformations
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Mappings between color spaces are ubiquitous in image processing problems such as gamut mapping, decolorization, and image optimization for color-blind people. Simple color transformations often result in information loss ... -
A Randomized Algorithm for Natural Object Colorization
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Natural objects often contain vivid color distribution with wide variety of colors. Conventional colorization techniques, on the other hand, produce colors that are relatively flat with little color variation. In this ... -
Perceptual Depth Compression for Stereo Applications
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Conventional depth video compression uses video codecs designed for color images. Given the performance of current encoding standards, this solution seems efficient. However, such an approach suffers from many issues ... -
Analogy-Driven 3D Style Transfer
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Style transfer aims to apply the style of an exemplar model to a target one, while retaining the target s structure. The main challenge in this process is to algorithmically distinguish style from structure, a high-level, ... -
Light Montage for Perceptual Image Enhancement
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Recent photography techniques such as sculpting with light show great potential in compositing beautiful images from fixed-viewpoint photos under multiple illuminations. The process relies heavily on the artists experience ... -
SimSelect: Similarity-based Selection for 3D Surfaces
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Surface selection is one of the fundamental interactions in shape modeling. In the case of complex models, this task is often tedious for at least two reasons: firstly the local geometry of a given region may be hard to ... -
Self-similarity for Accurate Compression of Point Sampled Surfaces
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Most surfaces, be it from a fine-art artifact or a mechanical object, are characterized by a strong self-similarity. This property finds its source in the natural structures of objects but also in the fabrication processes: ... -
Compressing Dynamic Meshes with Geometric Laplacians
(The Eurographics Association and John Wiley and Sons Ltd., 2014)This paper addresses the problem of representing dynamic 3D meshes in a compact way, so that they can be stored and transmitted efficiently. We focus on sequences of triangle meshes with shared connectivity, avoiding the ... -
3D Timeline: Reverse Engineering of a Part-based Provenance from Consecutive 3D Models
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a novel tool for reverse engineering of modeling histories from consecutive 3D files based on a timeline abstraction. Although a timeline interface is commonly used in 3D modeling packages for animations, it has ... -
ShapeSynth: Parameterizing Model Collections for Coupled Shape Exploration and Synthesis
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Recent advances in modeling tools enable non-expert users to synthesize novel shapes by assembling parts extracted from model databases. A major challenge for these tools is to provide users with relevant parts, which is ...
