    • Parallel Visibility Test and Occlusion Culling in Avango Virtual Environment Framework 

      Klimenko, Stanislav; Nikitina, Lialia; Nikitin, Igor (Eurographics Association, 2003)
      Real-time visibility test is an attractive feature for Virtual Environment (VE) applications where large datasets should be interactively explored. In such scenes most of the objects are usually occluded by other ones, and ...

    • Parameter-driven freeform deformations 

      Song, Y.; Vergeest, J.S.M.; Saakes, D.P. (Eurographics Association, 2003)
      High-level parameters offer user an easy and intuitive tool to modify an existing model. In this paper, an approach of deforming freeform shapes using intrinsic parameters is proposed, where those parameters were not part ...

    • Particle-based Collision Detection 

      Senin, Mikhail; Nikita, Kojekine; Savchenko, Vladimir; Hagiwara, Ichiro (Eurographics Association, 2003)
      In the paper we present a novel algorithm for collision detection between complex geometric objects represented by polygonal models and undergoing rigid motions and deformations. Most algorithms described in the literature ...

    • A Precise Approach Calibrated by Experimental Data to Make an Artificial Impulse 

      Iguchi, Toshiko; Kodama, Tetsuya; Noborio, Hiroshi (Eurographics Association, 2003)
      Baraffs and Mirtichs approaches are well known so as to generate force and impulsive force artificially at collision between rigid bodies. However, both cannot be unfortunately applied for a practical use such as complex ...

    • Precise Deformation of Rheology MSD Model Calibrated by Randomized Algorithm 

      Noborio, Hiroshi; Nogami, Ryo; Enoki, Ryo (Eurographics Association, 2003)
      In this paper, we propose and compare three kinds of mass-spring-damper (MSD) models of rheology object, and experimentally select the best model concerning to shape deformation and volume accuracy. The MSD model requires ...

    • Real-Time Simulation of Flexible Materials in Avango Virtual Environment Framework 

      Klimenko, Stanislav; Nikitina, Lialia; Nikitin, Igor (Eurographics Association, 2003)
      his paper describes a system for real-time simulation of linear elastic deformations of volumetric objects in Virtual Environments, implemented in Avango VE Framework 1. The approach makes use of the methods of Finite and ...

    • Reconstruction of Animatable Personalized 3D Faces by Adaptation-based Modeling 

      Zhang, Yu; Sim, Terence; Tan, Chew Lim (Eurographics Association, 2003)
      We present an efficient method for the construction of an animatable 3D facial model of a specific person with minimal user interaction. The method is based on adapting an anatomy-based prototype facial model that is ...

    • Shadow Mapping Based on Dual Depth Layers 

      Weiskopf, Daniel; Ertl, Thomas (Eurographics Association, 2003)
      Shadow maps are a widely used means for the generation of shadows although they exhibit aliasing artifacts and problems of numerical precision. In this paper we extend the concept of a single shadow map by introducing dual ...

    • Skeleton Subspace Deformation with Displacement Map 

      Liu, Feng; Liang, Ronghua; Ye, Dahai (Eurographics Association, 2003)
      Skeleton Subspace Deformation (SSD) is a novel Free Form Deformation technology (FFD), and plays an important role in character animation, interactive game and other fields. In this paper, we present a new layered algorithm ...

    • Trans-Polygon Stroke Method for Frame Coherent Pastel Images 

      Murakami, Kyoko; Tsuruno, Reiji (Eurographics Association, 2003)
      We propose Trans-Polygon Stroke Method (TPSM) for creating pastel-like animation that keeps frame-to-frame coherence. There are several variable factors in hand-drawn pastel such as paper roughness and pigments. When these ...

    • Uncertainty Visualization Methods in Isosurface Rendering 

      Rhodes, Philip J.; Laramee, Robert S.; Bergeron, R. Daniel; Sparr, Ted M. (Eurographics Association, 2003)
      We describe two techniques for rendering isosurfaces in multiresolution volume data such that the uncertainty (error) in the data is shown in the resulting visualization. In general the visualization of uncertainty in data ...

    • VelvetPath - Layout Design System with Sketch and Paint Manipulations 

      Tobita, Hiroaki (Eurographics Association, 2003)
      We describe the VelvetPath system, a system that allows users to design layouts for visualized information by using sketch and paint manipulations. Many systems enable users to visually search and browse through information ...

    • The Virtual Painting Paintbox 

      Sobczyk, D.; Boyer, V.; Bourdin, J-J. (Eurographics Association, 2003)
      We present VPUP8 a new kind of paint boxes. It includes a model for the simulation of physic dynamics involved in the painting process and a human-machine interface to manage the position and the moves of the user. Usually ...
