    • Knowledge-Based Representation of Cinematic Expression and its Application to Animation 

      Friedman, Doron; Feldman, Yishai (Eurographics Association, 2002)
      Camera control in virtual environments received growing attention recently, and some of the research turned to cinematography as a source for inspiration. Cinematic knowledge is a highly challenging domain for formalization. ...

    • Interpolating 2D Shape Hierarchically 

      Johan, Henry; Nishita, Tomoyuki (Eurographics Association, 2002)
      Shape interpolation has been widely used in the field of computer graphics for modeling and for creating visual effects. This paper presents a novel hierarchical method to interpolate between two 2D shapes. A hierarchical ...

    • Automatic Data Acquisition and Visualization for Usability Evaluation of Virtual Reality Systems 

      Holm, Roland; Priglinger, Markus; Stauder, Erwin; Volkert, J.; Wagner, R. (Eurographics Association, 2002)
      Evaluating the usability of a Virtual Reality system is a common practice nowadays. However, gathering and analyzing the necessary data are time-consuming tasks and sometimes involve inconvenient changes to the system. The ...

    • Interactive Polygonisation for Function-based Modelling 

      Sourin, Alexei; Levinski, Konstantin (Eurographics Association, 2002)
      This paper addresses interactive function-based shape modelling. Interactive modification of the function model with concurrent visualization of the respective polygonal mesh lets us provide both the interactivity and any ...

    • Feature interference in free form template matching 

      Song, Y.; Vergeest, J. S. M.; Horvath, I. (Eurographics Association, 2002)
      Template matching is a useful method in the reconstruction of free form surfaces. In this paper, matching of free form surfaces with parameterized templates is studied with the emphasis on feature interference. By their ...

    • Improved Bump Mapping by using Quadratic Vector Interpolation 

      Hast, Hans Anders; Barrera, Tony; Bengtsson, Ewert (Eurographics Association, 2002)
      Bump mapping is a technique that perturbs normals used in the illumination computation in order to make the surface appear rough or wrinkled. Standard graphics hardware linearly interpolates rotated vectors in the direction ...

    • Rendering of Japanese Artcraft 

      Durikovic, Roman; Kolchin, Kostantin; Ershov, Sergey (Eurographics Association, 2002)
      We present several methods for simulation of Japanese lacquer ware, a prominent Far East Asian handicraft art. We consider two most popular kinds of Japanese lacquer ware made by the makie and nashiji techniques. For ...

    • Rendering Artistic Line Drawings Using Off-the-Shelf 3-D Software 

      Loviscach, Jörn (Eurographics Association, 2002)
      Most commercial 3-D software packages used for animated films and still picture production offer merely rudimentary support for non-photorealistic rendering. However, nearly all of these packages possess interfaces which ...

    • Texture Minification using Quad-trees and Fipmaps 

      Bornik, Alexander; Ferko, Andrej (Eurographics Association, 2002)
      The paper extends the recently published methods for image reconstruction and texture minification using the generalized ripmap method, named fipmap, and quad-trees. Fipmap is based on the technique of partitioned iterated ...

    • Texture Mapping on Doo-Sabin Subdivision Surfaces Using Multiple Images 

      Huang, Zhiyong; Neo, Chee Seng (Eurographics Association, 2002)
      We propose a texture mapping method on subdivision surfaces using multiple images and have implemented it on Doo- Sabin scheme. At the beginning, one texture map is specified for each control mesh face respectively. In a ...

    • Tree balancing for mesh simplification 

      Grabner, Markus (Eurographics Association, 2002)
      In this paper, a tree balancing technique is presented that reduces the number of hierarchy levels in typical paircontraction based mesh simplification methods. A well-balanced hierarchy is essential for data structures ...

    • SAVANT: A new efficient approach to generating the visual hull 

      Lyons, Alex; Kotcheff, Aaron (Eurographics Association, 2002)
      We present a new approach to generating a boundary representation (a polygonal mesh) of the visual hull from a set of silhouettes of an object taken from known camera positions. The approach uses spatial subdivision to ...

    • Real-time 3D Deformations by Means of Compactly Supported Radial Basis Functions 

      Kojekine, Nikita; Savchenko, Vladimir; Senin, Mikhail; Hagiwara, Ichiro (Eurographics Association, 2002)
      We present an approach to real-time animation of deformable objects. Optimization of algorithms using compactly supported radial basis functions (CSRBF) allows us to generate deformations performed fast enough for such ...

    • Automated Enhancement of 3D Models 

      Torres-Mendez, L.A.; Dudek, G. (Eurographics Association, 2002)
      The acquisition of a 3D model of a real environment can be accomplished using range sensors. In practice, suitable sensors to densely cover a large environment are often impractical. This paper presents ongoing work on the ...

    • Flexible bump map capture from video 

      Paterson, James Alexander; Fitzgibbon, Andrew W. (Eurographics Association, 2002)
      We extend recent techniques for the automated capture of surface normal maps or bump maps from real-world material samples. In contrast to recent systems, which have required cumbersome laboratory setups with careful ...

    • Texturing Calibrated Head Model from Images 

      Lempitsky, Victor; Ivanov, Denis; Kuzmin, Yevgeniy (Eurographics Association, 2002)
