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 ... -
Flower Reconstruction from a Single Photo
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a semi-automatic method for reconstructing flower models from a single photograph. Such reconstruction is challenging since the 3D structure of a flower can appear ambiguous in projection. However, the flower ... -
Game Level Layout from Design Specification
(The Eurographics Association and John Wiley and Sons Ltd., 2014)The design of video game environments, or levels, aims to control gameplay by steering the player through a sequence of designer-controlled steps, while simultaneously providing a visually engaging experience. Traditionally ... -
Hierarchical Opacity Optimization for Sets of 3D Line Fields
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Abstract The selection of meaningful lines for 3D line data visualization has been intensively researched in recent years. Most approaches focus on single line fields where one line passes through each domain point. This ... -
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 ... -
Interactive Cloth Rendering of Microcylinder Appearance Model under Environment Lighting
(The Eurographics Association and John Wiley and Sons Ltd., 2014)This paper proposes an interactive rendering method of cloth fabrics under environment lighting. The outgoing radiance from cloth fabrics in the microcylinder model is calculated by integrating the product of the distant ... -
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 ... -
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 ... -
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 ... -
Manipulating Refractive and Reflective Binocular Disparity
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Presenting stereoscopic content on 3D displays is a challenging task, usually requiring manual adjustments. A number of techniques have been developed to aid this process, but they account for binocular disparity of surfaces ... -
Multi-style Paper Pop-up Designs from 3D Models
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Paper pop-ups are interesting three-dimensional books that fascinate people of all ages. The design and construction of these pop-up books however are done manually and require a lot of time and effort. This has led to ... -
Object Detection and Classification from Large-Scale Cluttered Indoor Scans
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a method to automatically segment indoor scenes by detecting repeated objects. Our algorithm scales to datasets with 198 million points and does not require any training data. We propose a trivially parallelizable ... -
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 ... -
On-the-fly Generation and Rendering of Infinite Cities on the GPU
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In this paper, we present a new approach for shape-grammar-based generation and rendering of huge cities in real-time on the graphics processing unit (GPU). Traditional approaches rely on evaluating a shape grammar and ... -
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 ... -
Optimizing Stereo-to-Multiview Conversion for Autostereoscopic Displays
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a novel stereo-to-multiview video conversion method for glasses-free multiview displays. Different from previous stereo-to-multiview approaches, our mapping algorithm utilizes the limited depth range of ... -
Panorama Light-Field Imaging
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a novel approach to recording and computing panorama light fields. In contrast to previous methods that estimate panorama light fields from focal stacks or naive multi-perspective image stitching, our approach ... -
Parallel Generation of Architecture on the GPU
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In this paper, we present a novel approach for the parallel evaluation of procedural shape grammars on the graphics processing unit (GPU). Unlike previous approaches that are either limited in the kind of shapes they allow, ... -
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 ... -
Pathline Glyphs
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Visualization of pathlines is common and highly relevant for the analysis of unsteady flow. However, pathlines can intersect, leading to visual clutter and perceptual issues. This makes it intrinsically difficult to provide ...
