    • Langevin Particle: A Self-Adaptive Lagrangian Primitive for Flow Simulation Enhancement 

      Chen, Fan; Zhao, Ye; Yuan, Zhi (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      We develop a new Lagrangian primitive, named Langevin particle, to incorporate turbulent flow details in fluid simulation. A group of the particles are distributed inside the simulation domain based on a turbulence energy ...
    • Learning Line Features in 3D Geometry 

      Sunkel, Martin; Jansen, Silke; Wand, Michael; Eisemann, Elmar; Seidel, Hans-Peter (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Feature detection in geometric datasets is a fundamental tool for solving shape matching problems such as partial symmetry detection. Traditional techniques usually employ a priori models such as crease lines that are ...
    • The Natural 3D Spiral 

      Harary, Gur; Tal, Ayellet (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Logarithmic spirals are ubiquitous in nature. This paper presents a novel mathematical definition of a 3D logarithmic spiral, which provides a proper description of objects found in nature. To motivate our work, we scanned ...
    • Paint Mesh Cutting 

      Fan, Lubin; Liu, Ligang; Liu, Kun (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      We present a novel progressive painting-based mesh cut out tool, called Paint Mesh Cutting, for interactive mesh segmentation. Different from the previous user interfaces, the user only needs to draw a single stroke on the ...
    • Predicted Virtual Soft Shadow Maps with High Quality Filtering 

      Shen, Li; Guennebaud, Gaël; Yang, Baoguang; Feng, Jieqing (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      In this paper we present a novel image based algorithm to render visually plausible anti-aliased soft shadows in a robust and efficient manner. To achieve both high visual quality and high performance, it employs an accurate ...
    • Preface and Table of Contents 

      Min Chen and Oliver Deussen (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    • Prior Knowledge for Part Correspondence 

      Kaick, Oliver van; Tagliasacchi, Andrea; Sidi, Oana; Zhang, Hao; Cohen-Or, Daniel; Wolf, Lior; Hamarneh, Ghassan (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Classical approaches to shape correspondence base their computation purely on the properties, in particular geometric similarity, of the shapes in question. Their performance still falls far short of that of humans in ...
    • Procedural Modeling of Interconnected Structures 

      Krecklau, Lars; Kobbelt, Leif (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      The complexity and detail of geometric scenes that are used in today's computer animated films and interactive games have reached a level where the manual creation by traditional 3D modeling tools has become infeasible. ...
    • RTSAH Traversal Order for Occlusion Rays 

      Ize, Thiago; Hansen, Charles (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      We accelerate the finding of occluders in tree based acceleration structures, such as a packetized BVH and a single ray kd-tree, by deriving the ray termination surface area heuristic (RTSAH) cost model for traversing an ...
    • Scalable Remote Rendering with Depth and Motion-flow Augmented Streaming 

      Paja, Dawid; Herzog, Robert; Eisemann, Elmar; Myszkowski, Karol; Seidel, Hans-Peter (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      In this paper, we focus on efficient compression and streaming of frames rendered from a dynamic 3D model. Remote rendering and on-the-fly streaming become increasingly attractive for interactive applications. Data is kept ...
    • Shape Analysis with Subspace Symmetries 

      Berner, Alexander; Wand, Michael; Mitra, Niloy J.; Mewes, Daniel; Seidel, Hans-Peter (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      We address the problem of partial symmetry detection, i.e., the identification of building blocks a complex shape is composed of. Previous techniques identify parts that relate to each other by simple rigid mappings, ...
    • A Sparse Parametric Mixture Model for BTF Compression, Editing and Rendering 

      Wu, Hongzhi; Dorsey, Julie; Rushmeier, Holly (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Bidirectional texture functions (BTFs) represent the appearance of complex materials. Three major shortcomings with BTFs are the bulky storage, the difficulty in editing and the lack of efficient rendering methods. To ...
    • SQuad: Compact Representation for Triangle Meshes 

      Gurung, Topraj; Laney, Daniel; Lindstrom, Peter; Rossignac, Jarek (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      The SQuad data structure represents the connectivity of a triangle mesh by its "S table" of about 2 rpt (integer references per triangle). Yet it allows for a simple implementation of expected constant-time, random-access ...
    • Symmetry Hierarchy of Man-Made Objects 

      Wang, Yanzhen; Xu, Kai; Li, Jun; Zhang, Hao; Shamir, Ariel; Liu, Ligang; Cheng, Zhi-Quan; Xiong, Y. (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      We introduce symmetry hierarchy of man-made objects, a high-level structural representation of a 3D model providing a symmetry-induced, hierarchical organization of the model's constituent parts. Given an input mesh, we ...
    • Two-Level Grids for Ray Tracing on GPUs 

      Kalojanov, Javor; Billeter, Markus; Slusallek, Philipp (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      We investigate the use of two-level nested grids as acceleration structure for ray tracing of dynamic scenes. We propose a massively parallel, sort-based construction algorithm and show that the two-level grid is one of ...
    • Walking On Broken Mesh: Defect-Tolerant Geodesic Distances and Parameterizations 

      Campen, Marcel; Kobbelt, Leif (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Efficient methods to compute intrinsic distances and geodesic paths have been presented for various types of surface representations, most importantly polygon meshes. These meshes are usually assumed to be well-structured ...
    • Wavelet Rasterization 

      Manson, Josiah; Schaefer, Scott (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      We present a method for analytically calculating an anti-aliased rasterization of arbitrary polygons or fonts bounded by Bezier curves in 2D as well as oriented triangle meshes in 3D. Our algorithm rasterizes multiple ...
