    • Global Illumination Compensation for Spatially Augmented Reality 

      Sheng, Yu; Yapo, Theodore C.; Cutler, Barbara (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      When projectors are used to display images on complex, non-planar surface geometry, indirect illumination between the surfaces will disrupt the final appearance of this imagery, generally increasing brightness, decreasing ...

      Hierarchical culling is a key acceleration technique used to efficiently handle massive models for ray tracing, collision detection, etc. To support such hierarchical culling, bounding volume hierarchies (BVHs) combined ...
    • Heat Transfer Simulation for Modeling Realistic Winter Sceneries 

      Marechal, N.; Guerin, E.; Galin, E.; Merillou, S.; Merillou, N. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      This paper presents a physically based method for simulating the heat transfers between the different environmental elements to synthesize realistic winter sceneries. We simulate the snow fall over the ground, as well as ...
    • Human Motion Synthesis with Optimization-based Graphs 

      Ren, Cheng; Zhao, Liming; Safonova, Alla (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Continuous constrained optimization is a powerful tool for synthesizing novel human motion segments that are short. Graph-based motion synthesis methods such as motion graphs and move trees are popular ways to synthesize ...
    • A Hybrid Approach to Multiple Fluid Simulation using Volume Fractions 

      Kang, Nahyup; Park, Jinho; Noh, Junyong; Shin, Sung Yong (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      This paper presents a hybrid approach to multiple fluid simulation that can handle miscible and immiscible fluids, simultaneously. We combine distance functions and volume fractions to capture not only the discontinuous ...
    • Hybrid Simulation of Miscible Mixing with Viscous Fingering 

      Shin, Seung-Ho; Kam, Hyeong Ryeol; Kim, Chang-Hun (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      By modeling mass transfer phenomena, we simulate solids and liquids dissolving or changing to other substances. We also deal with the very small-scale phenomena that occur when a fluid spreads out at the interface of another ...
    • Implicit Blending Revisited 

      Bernhardt, Adrien; Barthe, Loic; Cani, Marie-Paule; Wyvill, Brian (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Blending is both the strength and the weakness of functionally based implicit surfaces (such as F-reps or soft-objects). While it gives them the unique ability to smoothly merge into a single, arbitrary shape, it makes ...
    • Improved Variational Guiding of Smoke Animations 

      Nielsen, Michael B.; Christensen, Brian B. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Smoke animations are hard to art-direct because simple changes in parameters such as simulation resolution often lead to unpredictable changes in the final result. Previous work has addressed this problem with a guiding ...
    • Interactive High-Quality Visualization of Higher-Order Finite Elements 

      Ueffinger, Markus; Frey, Steffen; Ertl, Thomas (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Higher-order finite element methods have emerged as an important discretization scheme for simulation. They are increasingly used in contemporary numerical solvers, generating a new class of data that must be analyzed by ...
    • Inverse Procedural Modeling by Automatic Generation of L-systems 

      St ava, O.; Benes, B.; Mech, R.; Aliaga, D. G.; Kristof, P. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We present an important step towards the solution of the problem of inverse procedural modeling by generating parametric context-free L-systems that represent an input 2D model. The L-system rules efficiently code the ...
    • Isosurfaces Over Simplicial Partitions of Multiresolution Grids 

      Manson, Josiah; Schaefer, Scott (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We provide a simple method that extracts an isosurface that is manifold and intersection-free from a function over an arbitrary octree. Our method samples the function dual to minimal edges, faces, and cells, and we show ...
    • Mesh Decomposition with Cross-Boundary Brushes 

      Zheng, Youyi; Tai, Chiew-Lan (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We present a new intuitive UI, which we call cross-boundary brushes, for interactive mesh decomposition. The user roughly draws one or more strokes across a desired cut and our system automatically returns a best cut running ...
    • Mesh Snapping: Robust Interactive Mesh Cutting Using Fast Geodesic Curvature Flow 

      Zhang, Juyong; Wu, Chunlin; Cai, Jianfei; Zheng, Jianmin; Tai, Xue-cheng (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      This paper considers the problem of interactively finding the cutting contour to extract components from a given mesh. Some existing methods support cuts of arbitrary shape but require careful and tedious input from the ...
    • Motion Blur for EWA Surface Splatting 

      Heinzle, Simon; Wolf, Johanna; Kanamori, Yoshihiro; Weyrich, Tim; Nishita, Tomoyuki; Gross, Markus (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      This paper presents a novel framework for elliptical weighted average (EWA) surface splatting with time-varying scenes. We extend the theoretical basis of the original framework by replacing the 2D surface reconstruction ...
    • Multi-Scale Geometry Interpolation 

      Winkler, T.; Drieseberg, J.; Alexa, M.; Hormann, K. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Interpolating vertex positions among triangle meshes with identical vertex-edge graphs is a fundamental part of many geometric modelling systems. Linear vertex interpolation is robust but fails to preserve local shape. ...
    • Optimizing Photo Composition 

      Liu, Ligang; Chen, Renjie; Wolf, Lior; Cohen-Or, Daniel (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Aesthetic images evoke an emotional response that transcends mere visual appreciation. In this work we develop a novel computational means for evaluating the composition aesthetics of a given image based on measuring several ...
    • Perceptually-motivated Real-time Temporal Upsampling of 3D Content for High-refresh-rate Displays 

      Didyk, Piotr; Eisemann, Elmar; Ritschel, Tobias; Myszkowski, Karol; Seidel, Hans-Peter (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      High-refresh-rate displays (e. g., 120 Hz) have recently become available on the consumer market and quickly gain on popularity. One of their aims is to reduce the perceived blur created by moving objects that are tracked ...

    • Printed Patterns for Enhanced Shape Perception of Papercraft Models 

      Xue, Su; Chen, Xuejin; Dorsey, Julie; Rushmeier, Holly (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Papercraft models can serve as inexpensive prototypes in shape design applications. However, in making the models some geometric detail is necessarily lost, and artificial creases may be visible, thereby limiting the utility ...
