Second-Order Approximation for Variance Reduction in Multiple Importance Sampling
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Monte Carlo Techniques are widely used in Computer Graphics to generate realistic images. Multiple Importance Sampling reduces the impact of choosing a dedicated strategy by balancing the number of samples between different ... -
Modeling by Drawing with Shadow Guidance
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Modeling 3D objects is difficult, especially for the user who lacks the knowledge on 3D geometry or even on 2D sketching. In this paper, we present a novel sketch-based modeling system which allows novice users to create ... -
Eye-Centered Color Adaptation in Global Illumination
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Color adaptation is a well known ability of the human visual system (HVS). Colors are perceived as constant even though the illuminant color changes. Indeed, the perceived color of a diffuse white sheet of paper is still ... -
Interactive Physics-based Ink Splattering Art Creation
(The Eurographics Association and Blackwell Publishing Ltd., 2013)This paper presents an interactive system for ink splattering, a form of abstract art that artists splat ink onto the canvas. The default input device of our system is a pressure-sensitive 2D stylus, the most common sketching ... -
Artistic QR Code Embellishment
(The Eurographics Association and Blackwell Publishing Ltd., 2013)A QR code is a two-dimensional barcode that encodes information. A standard QR code contains only regular black and white squares, and thus is unattractive. This paper proposes a novel framework for embellishing a standard ... -
Robust Denoising using Feature and Color Information
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We propose a method that robustly combines color and feature buffers to denoise Monte Carlo renderings. On one hand, feature buffers, such as per pixel normals, textures, or depth, are effective in determining denoising ... -
Guided Real-Time Scanning of Indoor Objects
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Advances in 3D acquisition devices provide unprecedented opportunities for quickly scanning indoor environments. Such raw scans, however, are often noisy, incomplete, and significantly corrupted, making semantic scene ... -
Soft Folding
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We introduce soft folding, a new interactive method for designing and exploring thin-plate forms. A user specifies sharp and soft folds as two-dimensional(2D) curves on a flat sheet, along with the fold magnitude and ... -
TrayGen: Arranging Objects for Exhibition and Packaging
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We present a framework, called TrayGen, to generate tray designs for the exhibition and packaging of a collection of objects. Based on principles from shape perception and visual merchandising, we abstract a number of ... -
A Semi-Lagrangian Closest Point Method for Deforming Surfaces
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We present an Eulerian method for the real-time simulation of intrinsic fluid dynamics effects on deforming surfaces. Our method is based on a novel semi-Lagrangian closest point method for the solution of partial differential ... -
The POP Buffer: Rapid Progressive Clustering by Geometry Quantization
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Within this paper, we present a novel, straightforward progressive encoding scheme for general triangle soups, which is particularly well-suited for mobile and Web-based environments due to its minimal requirements on the ... -
Fast Image-Based Modeling of Astronomical Nebulae
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Astronomical nebulae are among the most complex and visually appealing phenomena known outside the bounds of the Solar System. However, our fixed vantage point on Earth limits us to a single known view of these objects, ... -
Lighting Simulation of Augmented Outdoor Scene Based on a Legacy Photograph
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We propose a novel approach to simulate the illumination of augmented outdoor scene based on a legacy photograph. Unlike previous works which only take surface radiosity or lighting related prior information as the basis ... -
Still-Frame Simulation for Fire Effects of Images
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We propose various simulation strategies to generate single-frame fire effects for images, as opposed to multiframe fire effects for animations. To accelerate 3D simulation and to provide a user with early hints on the ... -
Efficient Smoke Simulation on Curvilinear Grids
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We present an efficient approach for performing smoke simulation on curvilinear grids. Our technique is based on a fast unconditionally-stable advection algorithm and on a new and efficient solution to enforce mass ... -
Boundary-Aware Extinction Mapping
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We introduce Boundary-Aware Extinction Maps for interactive rendering of massive heterogeneous volumetric datasets. Our approach is based on the projection of the extinction along light rays into a boundary-aware function ... -
Implicit Integration for Particle-based Simulation of Elasto-Plastic Solids
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We present a novel particle-based method for stable simulation of elasto-plastic materials. The main contribution of our method is an implicit numerical integrator, using a physically-based model, for computing particles ... -
Adaptive Ray-bundle Tracing with Memory Usage Prediction: Efficient Global Illumination in Large Scenes
(The Eurographics Association and Blackwell Publishing Ltd., 2013)This paper proposes an adaptive rendering technique for ray-bundle tracing. Ray-bundle tracing can be done by per-pixel linked-list construction on a GPU rasterization pipeline. This rasterization based approach offers ... -
A Progressive Tri-level Segmentation Approach for Topology-Change-Aware Video Matting
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Previous video matting approaches mostly adopt the ''binary segmentation + matting'' strategy, i.e., first segment each frame into foreground and background regions, then extract the fine details of the foreground boundary ... -
Multiplane Video Stabilization
(The Eurographics Association and Blackwell Publishing Ltd., 2013)This paper presents a novel video stabilization approach by leveraging the multiple planes structure of video scene to stabilize inter-frame motion. As opposed to previous stabilization procedure operating in a single ...
