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 ... -
Improving Memory Space Efficiency of Kd-tree for Real-time Ray Tracing
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Compared with its competitors such as the bounding volume hierarchy, a drawback of the kd-tree structure is that a large number of triangles are repeatedly duplicated during its construction, which often leads to inefficient, ... -
Interactive Learning for Point-Cloud Motion Segmentation
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Segmenting a moving foreground (fg) from its background (bg) is a fundamental step in many Machine Vision and Computer Graphics applications. Nevertheless, hardly any attempts have been made to tackle this problem in dynamic ... -
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 ... -
Learning and Applying Color Styles From Feature Films
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Directors employ a process called ''color grading'' to add color styles to feature films. Color grading is used for a number of reasons, such as accentuating a certain emotion or expressing the signature look of a director. ... -
Learning to Predict Localized Distortions in Rendered Images
(The Eurographics Association and Blackwell Publishing Ltd., 2013)In this work, we present an analysis of feature descriptors for objective image quality assessment. We explore a large space of possible features including components of existing image quality metrics as well as many ... -
Level-of-Detail Streaming and Rendering using Bidirectional Sparse Virtual Texture Functions
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Bidirectional Texture Functions (BTFs) are among the highest quality material representations available today and thus well suited whenever an exact reproduction of the appearance of a material or complete object is required. ... -
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 ... -
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 ... -
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 ... -
Ontology-based Model for Chinese Calligraphy Synthesis
(The Eurographics Association and Blackwell Publishing Ltd., 2013)There are lots of digitized Chinese calligraphic works written by ancient calligraphists in CADAL. Sometimes users want to generate a tablet or a piece of calligraphic work written by these calligraphists. However, some ... -
Polar NURBS Surface with Curvature Continuity
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Polar NURBS surface is a kind of periodic NURBS surface, one boundary of which shrinks to a degenerate polar point. The specific topology of its control-point mesh offers the ability to represent a cap-like surface, which ... -
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 ... -

A Programmable Graphics Processor based on Partial Stream Rewriting
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Current graphics processing units (GPU) typically offer only a limited number of programmable pipeline stages, whose usage, data flow and topology are mostly fixed. Although a more flexible, custom rendering pipeline can ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ...
