    • Robust Denoising using Feature and Color Information 

      Rousselle, Fabrice; Manzi, Marco; Zwicker, Matthias (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 

      Lu, Heqi; Pacanowski, Romain; Granier, Xavier (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 

      Auer, Stefan; Westermann, Rüdiger (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 

      Zhu, Lifeng; Igarashi, Takeo; Mitani, Jun (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 ...

    • Still-Frame Simulation for Fire Effects of Images 

      Son, Minjung; Kim, Byungmoon; Wilensky, Gregg; Lee, Seungyong (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 ...

    • Stroke-guided Image Synthesis for Skeletal Structure Editing 

      Luo, Sheng-Jie; Lin, Chin-Yu; Shen, I-Chao; Chen, Bing-Yu (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Creating variations of an image object is an important task, which usually requires manipulating the skeletal structure of the object. However, most existing methods (such as image deformation) only allow for stretching ...

    • Symmetry Robust Descriptor for Non-Rigid Surface Matching 

      Zhang, Zhiyuan; Yin, KangKang; Foong, Kelvin W. C. (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      In this paper, we propose a novel shape descriptor that is robust in differentiating intrinsic symmetric points on geometric surfaces. Our motivation is that even the state-of-the-art shape descriptors and non-rigid surface ...

    • Synthesizing Two-character Interactions by Merging Captured Interaction Samples with their Spacetime Relationships 

      Chan, Jacky C. P.; Tang, Jeff K. T.; Leung, Howard (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Existing synthesis methods for closely interacting virtual characters relied on user-specified constraints such as the reaching positions and the distance between body parts. In this paper, we present a novel method for ...

    • Topology Aware Data-Driven Inverse Kinematics 

      Ho, Edmond S. L.; Shum, Hubert P. H.; Cheung, Yiu-ming; Yuen, P. C. (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Creating realistic human movement is a time consuming and labour intensive task. The major difficulty is that the user has to edit individual joints while maintaining an overall realistic and collision free posture. Previous ...

    • TrayGen: Arranging Objects for Exhibition and Packaging 

      Yang, Yong-Liang; Huang, Qi-Xing (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 ...
