    • Real-time Rigid Body Simulation for Haptic Interactions Based on Contact Volume of Polygonal Objects 

      Hasegawa, S.; Sato, M. (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      This paper proposes a new method for real-time rigid body simulations for haptic interactions based on a penalty method regarding contact volume. Analytical methods for calculation of contact forces require too much time ...

    • Scalable behaviors for crowd simulation 

      Sung, Mankyu; Gleicher, Michael; Chenney, Stephen (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      Crowd simulation for virtual environments offers many challenges centered on the trade-offs between rich behavior, control and computational cost. In this paper we present a new approach to controlling the behavior of ...

    • Crowd of Virtual Humans: a New Approach for Real Time Navigation in Complex and Structured Environments 

      Lamarche, Fabrice; Donikian, Stephane (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      The navigation activity is an every day practice for any human being capable of locomotion. Our objective in this work is to reproduce this crucial human activity inside virtual environments. Putting together the high ...

    • Way-Finder: guided tours through complex walkthrough models 

      Andujar, C.; Vazquez, P.; Fairen, M. (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      The exploration of complex walkthrough models is often a difficult task due to the presence of densely occluded regions which pose a serious challenge to online navigation. In this paper we address the problem of algorithmic ...

    • Instant Volumetric Understanding with Order-Independent Volume Rendering 

      Mora, Benjamin; Evert, David S. (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      Rapid, visual understanding of volumetric datasets is a crucial outcome of a good volume rendering application, but few current volume rendering systems deliver this result. Our goal is to reduce the volumetric surfing ...

    • Topological Construction and Visualization of Higher Order 3D Vector Fields 

      Weinkauf, Tino; Theisel, Holger; Hege, Hans-Christian; Seidel, Hans-Peter (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      We present the first algorithm for constructing 3D vector fields based on their topological skeleton. The skeleton itself is modeled by interactively moving a number of control polygons. Then a piecewise linear vector field ...

    • Dye Advection Without the Blur: A Level-Set Approach for Texture-Based Visualization of Unsteady Flow 

      Weiskopf, D. (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      Dye advection is an intuitive and versatile technique to visualize both steady and unsteady flow. Dye can be easily combined with noise-based dense vector field representations and is an important element in user-centric ...

    • Quadric Transfer for Immersive Curved Screen Displays 

      Raskar, Ramesh; van Baar, Jeroen; Willwacher, Thomas; Rao, Srinivas (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      Curved screens are increasingly being used for high-resolution immersive visualization environments. We describe a new technique to display seamless images using overlapping projectors on curved quadric surfaces such as ...

    • Procedural Texture Matching and Transformation 

      Bourque, Eric; Dudek, Gregory (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      We present a technique for creating a smoothly varying sequence of procedural textures that interpolates between arbitrary input samples of texture. This texture transformation uses a library of procedural shaders and ...

    • High Quality Hatching 

      Zander, Johannes; Isenberg, Tobias; Schlechtweg, Stefan; Strothotte, Thomas (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      Hatching lines are often used in line illustrations to convey tone and texture of a surface. In this paper we present methods to generate hatching lines from polygonal meshes and render them in high quality either at ...

    • The Design of an Inexpensive Very High Resolution Scan Camera System 

      Wang, Shuzhen; Heidrich, Wolfgang (The Eurographics Association and Blackwell Publishing, Inc, 2004)

    • Virtual Drypoint by a Model-driven Strategy 

      Tasaki, Daisuke; Mizuno, Shinji; Okada, Minoru (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      In this paper we propose a method to synthesize a virtual copperplate print image based on physical model as a non-photorealistic rendering in Computer Graphics. In particular we pick out the drypoint from many existing ...

    • Computing Maximal Tiles and Application to Impostor-Based Simplification 

      Andujar, C.; Brunet, P.; Chica, A.; Navazo, I.; Rossignac, J.; Vinacua, A. (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      The computation of the largest planar region approximating a 3D object is an important problem with wide applications in modeling and rendering. Given a voxelization of the 3D object, we propose an efficient algorithm to ...

    • A System for View-Dependent Animation 

      Chaudhuri, Parag; Kalra, Prem; Banerjee, Subhashis (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      In this paper, we present a novel system for facilitating the creation of stylized view-dependent 3D animation. Our system harnesses the skill and intuition of a traditionally trained animator by providing a convivial ...

    • Anisotropic Filtering of Non-Linear Surface Features 

      Hildebrandt, Klaus; Polthier, Konrad (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      A new method for noise removal of arbitrary surfaces meshes is presented which focuses on the preservation and sharpening of non-linear geometric features such as curved surface regions and feature lines. Our method uses ...

    • Single-Strip Triangulation of Manifolds with Arbitrary Topology
