    • Morphing Rational B-spline Curves and Surfaces Using Mass Distributions 

      Ju, Tao; Goldman, Ron (Eurographics Association, 2003)
      A rational B-spline curve or surface is a collection of points associated with a mass (weight) distribution. These mass distributions can be used to exert local control over the morph between two rational B-spline curves ...

    • Occlusion Culling for Image-Based Rendering withWarping 

      Soner, I. Sen; Atalay, Volkan (Eurographics Association, 2003)
      The basic idea of the proposed algorithm is to reduce the number of depth pixels in Layer Depth Images (LDI) by culling the occluded ones before warping. The method combines the octree spatial subdivision concept with LDI ...

    • On the characterization of avatars in Distributed Virtual Worlds 

      Morillo, Pedro; Fernandez, Marcos; Orduna, Juan Manuel (Eurographics Association, 2003)
      Current Distributed Virtual Environment (DVE) systems run simulations based on a server-network architecture, where the population of avatars should be properly assigned to the servers in the DVE. This goal, called ...

    • 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 ...
